Introduction
Ethernet RJ-45 Ports
The wireless AP/Router has the following RJ-45 ports:
• The four RJ-45 LAN ports are for connections to PCs or to a 10/100 Mbps network
switch.
• The RJ-45 WAN port is for connection to a DSL or cable modem, or to a LAN or
other device that provides your Internet access.
All RJ-45 ports auto-negotiate the operating speed to 10/100 Mbps, the mode to
half/full duplex, and the pin signals to MDI/MDI-X. Automatic MDI/MDI-X support
enables you to use straight-through cables for all network connections to PCs,
switches, or hubs.
Power Socket
The wireless AP/Router does not have a power switch. It is powered on when
connected to the AC power adapter, and the power adapter is connected to a power
source. The power adapter automatically adjusts to any voltage between 100-240
volts at 50 or 60 Hz. No voltage range settings are required.
Reset Button
The Reset button can be used to restart the wireless AP/Router or restore the
factory default configuration. If you press the button for less than 5 seconds, the
wireless AP/Router will restart. If you press and hold down the button for 5 seconds
or more, any configuration changes you may have made are removed and the
wireless AP/Router is restored to its factory default configuration.
WPS Button
Use the WPS button on the wireless AP/Router to automatically connect devices to
the network. Within two minutes, press the physical or virtual button on a single
wireless client device to enable it to join the WLAN.
The WPS configuration process may be initiated on any device. Only one client
device can connect with the wireless AP/Router after the WPS button is pressed.
There is no restriction to the order in which buttons are pressed.
Note: Any WPS-compatible devices could unintentionally join the WLAN if they are
within range during the two-minute set up period after the WPS button is pressed.
Note that only one device at a time can join the network when using the WPS
button.

Introduction
Chapter 2: Installation
The wireless AP/Router has two basic operating modes that can be set through the
web-based management interface. For information on setting the mode suitable for
your network environment, see “Operation Mode configuration” on page 5-4.
• Gateway Mode — A gateway mode that connects a wired LAN and wireless clients
to an Internet access device, such as a cable or DSL modem. This is the factory
set default mode.
• Bridge Mode — An access point mode that extends a wired LAN to wireless
clients.
In addition to these basic operating modes, the wireless interface supports a
Wireless Distribution System (WDS) link to another wireless AP/Router. These
advanced configurations are not described in this section. See “Network Planning”
on page 3-1 for more information.
In a basic configuration, how the wireless AP/Router is connected depends on the
operating mode. The following sections describe connections for basic Gateway
Mode and Bridge Mode operation.
Gateway Mode
In its default Gateway Mode, the wireless AP/Router forwards traffic between an
Internet connected cable or ADSL modem, and wired or wireless PCs or notebooks.

Chapter 3: Network Planning
The wireless AP/Router is designed to be very flexible in its deployment options. It
can be used as an Internet gateway for a small network, or as an access point to
extend an existing wired network to support wireless users. It also supports use as a
wireless bridge to connect two wired LANs.
This chapter explains some of the basic features of the wireless AP/Router and
shows some network topology examples in which the device is implemented.
Internet Gateway Router
The wireless AP/Router can connect directly to a cable or DSL modem to provide an
Internet connection for multiple users through a single service provider account.
Users connect to the wireless AP/Router either through a wired connection to a LAN
port, or though the device’s own wireless network. The wireless AP/Router functions
as an Internet gateway when set to Gateway Mode.
An Internet gateway employs several functions that essentially create two separate
Internet Protocol (IP) subnetworks; a private internal network with wired and
wireless users, and a public external network that connects to the Internet. Network
traffic is forwarded, or routed, between the two subnetworks.

Network Planning
The private local network, connected to the LAN port or wireless interface, provides
a Dynamic Host Configuration Protocol (DHCP) server for allocating IP addresses to
local PCs and wireless clients, and Network Address Translation (NAT) for mapping
the multiple &quot;internal&quot; IP addresses to one &quot;external&quot; IP address.
The public external network, connected to the WAN port, supports DHCP client,
Point-to-Point Protocol over Ethernet (PPPoE), static IP for connection, L2TP and
PPTP to an Internet service provider (ISP) through a cable or DSL modem.
LAN Access Point
The wireless AP/Router can provide an access point service for an existing wired
LAN, creating a wireless extension to the local network. The wireless AP/Router
functions as purely an access point when set to Bridge Mode. When used in this
mode, there are no gateway functions between the WAN port and the LAN and
wireless interface.
A Wi-Fi wireless network is defined by its Service Set Identifier (SSID) or network
name. Wireless clients that want to connect to a network must set their SSID to the
same SSID of the network service. The wireless AP/Router supports two separate
wireless interfaces, that is two SSIDs or Virtual Access Points (VAPs). The two VAP
interfaces can be configured separately to support different security settings or other
wireless functions.

Wireless Bridge
The IEEE 802.11 standard defines a Wireless Distribution System (WDS) for bridge
connections between access points. The wireless AP/Router can use WDS to
forward traffic on links between units.
A single WDS bridge link can be specified for the WLAN1 interface. One end of a
link must be configured as the “WDS Parent” and the other as the “WDS Child.”
Note: The network domain of WDS child has to be the same as WDS parent.

Chapter 4: Initial Configuration
The wireless AP/Router offers a user-friendly web-based management interface for
the configuration of all the unit’s features. Any PC directly attached to the unit can
access the management interface using a web browser, such as Internet Explorer
(version 6.0 or above).
This chapter describes the wireless AP/Router’s configurable features, all of which
may be accessed through the web interface.
It is recommended to make initial configuration changes by connecting a PC directly
to one of the wireless AP/Router's LAN ports. The wireless AP/Router has a default
IP address of 192.168.2.1 and a subnet mask of 255.255.255.0. If your PC is set to
“Obtain an IP address automatically” (that is, set as a DHCP client), you can connect
immediately to the web interface. Otherwise, you must set your PC IP address to be
on the same subnet as the wireless AP/Router (that is, the PC and wireless AP/
Router addresses must both start 192.168.2.x).
To access the configuration menu, follow these steps:
1.
Use your web browser to connect to the management interface using the
default IP address of 192.168.2.1.
2.
Log into the wireless AP/Router management interface by entering the default
username “admin” and password “smcadmin”, then click OK.
Note: It is strongly recommended to change the default user name and password the
first time you access the web interface. For information on changing user names
and passwords, See “Administrator Settings” on page 5-45.

Chapter 5: System Configuration
The wireless AP/Router offers a user-friendly web-based management interface for
the configuration of all the unit’s features. Any PC directly attached to the unit can
access the management interface using a web browser, such as Internet Explorer
(version 6.0 or above).
This chapter describes the wireless AP/Router’s configurable features, all of which
may be accessed through the web interface.
It is recommended to make initial configuration changes by connecting a PC directly
to one of the wireless AP/Router's LAN ports. The wireless AP/Router has a default
IP address of 192.168.2.1 and a subnet mask of 255.255.255.0. If your PC is set to
“Obtain an IP address automatically” (that is, set as a DHCP client), you can connect
immediately to the web interface. Otherwise, you must set your PC IP address to be
on the same subnet as the wireless AP/Router (that is, the PC and wireless AP/
Router addresses must both start 192.168.2.x).
To access the configuration menu, follow these steps:
1.
Use your web browser to connect to the management interface using the
default IP address of 192.168.2.1.
2.
Log into the wireless AP/Router management interface by entering the default
username “admin” and password “smcadmin,” then click OK.
Note: It is strongly recommended to change the default user name and password the
first time you access the web interface. For information on changing user names
and passwords, See “Administrator Settings” on page 5-45

Routing Table
This page displays the information necessary to forward a packet along the best
path toward its destination. Each packet contains information about its origin and
destination. When a packet is received, a network device examines the packet and
matches it to the routing table entry providing the best match for its destination. The
table then provides the device with instructions for sending the packet to the next
hop on its route across the network.
Note: The Routing Table is only available when the wireless AP/Router is set to
Gateway Mode.

• Destination – Displays all destination networks or specific hosts to which packets
can be routed.
• Netmask – Displays the subnetwork associated with the destination.
• Gateway – Displays the IP address of the router at the next hop to which matching
frames are forwarded.
• Flags – Possible flags identify as below
- 0: reject route
- 1: route is up

Dynamic Route
The wireless AP/Router supports RIP 1 and RIP 2 dynamic routing protocol. Routing
Information Protocol (RIP) is the most widely used method for dynamically
maintaining routing tables. RIP uses a distance vector-based approach to routing.
Routes are chosen to minimize the distance vector, or hop count, which serves as a
rough estimate of transmission cost. Each router broadcasts its advertisement every
30 seconds, together with any updates to its routing table. This allows all routers on
the network to build consistent tables of next hop links which lead to relevant
subnets.
Figure 5-12. Dynamic Route (Gateway Mode)
• RIP – Enables or disable the RIP protocol for the WAN or LAN interface. (Options:
Disable/v1/v2, Default: Disable)
QoS Setting
The QoS setting page is used to configure Quality of Service (QoS) for Traffic
Prioritization and Bandwidth Management. Quality of Service (QoS) provides users
the control over which type of outgoing data traffic is given priority by the router. The
throughput rate of the upload data passed through the wireless AP/Router can be
throttled. Click on “Network Settings” followed by “QoS”.

• SIP Support – Allows SIP packets to pass through the wireless AP/Router.
Wireless Settings
The IEEE 802.11n interfaces include configuration options for radio signal
characteristics and wireless security features.
The wireless AP/Router can operate in five modes, mixed 802.11b/g/n, mixed
802.11b/g, 802.11b only and 802.11g only. Also note that 802.11g is backward
compatible with 802.11b, and 802.11n is backward compatible with both 802.11b/g
at slower data transmit rates.
Each radio supports two virtual access point (VAP) interfaces, referred to as WLAN1
and WLAN2. Each VAP functions as a separate access point, and can be configured
with its own Service Set Identification (SSID) and security settings. However, most
radio signal parameters apply to both VAP interfaces. The configuration options are
nearly identical, and are therefore both covered in this section of the manual.
5-16
5
Wireless Settings
Traffic to specific VAPs can be segregated based on user groups or application
traffic. Both VAPs can have up to 64 wireless clients, whereby the clients associate
with these VAPs the same as they would with a physical access point.
Note: The radio channel settings for the access point are limited by local regulations,
which determine the number of channels that are available. See “Specifications”
on page B-1 for additional information on the maximum number channels
available.
Basic Settings
The Basic Setting page allows you to enable the wireless interface, select which
radio mode to use, choose the transmit frequency and configure SSIDs.
Click on “Wireless Settings,” followed by “Basic”.
Note: There are several variables to consider when selecting a radio mode that make it
fully functional. Simply selecting the mode you want is not enough to ensure full
compatibility for that mode. Information on these variables may be found in the
Advanced Setting section.
Figure 5-15. Basic Wireless Settings
• Radio On/Off – Enables or Disable the radio. (Default: Enable)
• Network Mode – Defines the radio mode for the VAP interface.
(Default: 802.11b/g/n Mixed)
Note: Enabling the wireless AP/Router to communicate with 802.11b/g clients in both
802.11b/g/n Mixed and 802.11n modes also requires that HT Operation in the

System Configuration
Advanced Settings menu be set to Mixed. Setting HT Operation to Green Field is
exclusive for 802.11n client communication only and prevents 802.11 b/g
communication.
- 802.11b/g Mixed: Both 802.11b and
802.11g clients can communicate with
the wireless AP/Router (up to 108
Mbps), but data transmission rates may
be slowed to compensate for 802.11b
clients. Any 802.11n clients will also be
able to communicate with the wireless AP/Router, but they will be limited to
802.11g protocols and data transmission rates.
- 802.11b only: All 802.11b, 802.11g, and 802.11n clients will be able to
communicate with the wireless AP/Router, but the 802.11g and 802.11n clients
will be limited to 802.11b protocols and data transmission rates (up to 11 Mbps).
- 802.11g only: Both 802.11g and 802.11n clients will be able to communicate
with the wireless AP/Router, but the 802.11n clients will be limited to 802.11g
protocols and data transmission rates (up to 54 Mbps). Any 802.11b clients will
not be able to communicate with the wireless AP/Router.
- 802.11b/g/n Mixed: All 802.11b/g/n clients can communicate with the wireless
AP/Router (up to 300 Mbps), but data transmission rates may be slowed to
compensate for 802.11b/g clients.
• Network Name (SSID) – The name of the wireless network service provided by
the VAP. Clients that want to connect to the network must set their SSID to the
same as that of the VAP interface. (Default: “SMC”; Range: 1-32 characters)
- Multiple SSID – The number of wireless network interfaces (SSIDs) supported
on the device.
• Broadcast Network Name (SSID) – The wireless AP/Router will broadcast its
SSID.
• AP Isolation – The wireless AP/Router will isolate wireless clients in order to
protect them. Normally for users who are at hotspots.
• MBSSID AP Isolation – The wireless AP/Router will isolate wireless clients from
different SSID.
• BSSID – The identifier (MAC address) of a wireless AP/Router in a Basic Service
Set (BSS) network.
• WLAN Frequency – The radio channel
that the wireless AP/Router uses to
communicate with wireless clients. When
multiple access points are deployed in the
same area, set the channel on
neighboring access points at least five
channels apart to avoid interference with
each other. For example, you can deploy
up to three access points in the same area
using channels 1, 6, 11. Note that wireless clients automatically set the channel to
5-18

Wireless Settings
the same as that used by the wireless AP/Router to which it is linked. Selecting
Auto Select enables the wireless AP/Router to automatically select an unoccupied
radio channel.
Wireless Distribution System (WDS)
The WLAN1 radio interface can be configured to operate in a mode that allows it to
forward traffic directly to other access point units. To set up links between access
point units, you must configure the Wireless Distribution System (WDS) forwarding
table by specifying the wireless MAC address of all units to which you want to
forward traffic.
Traffic forwarded to WDS links is automatically converted to 802.11 four-address
format frame. This uses the MAC addresses of the station and that of the AP
connected to it on the transmitting LAN, and the MAC addresses of the AP
functioning as a wireless repeater/bridge and that of the station connected to it on a
neighboring LAN in the 802.11 frame header. Ethernet traffic follows a three-address
format that is reconstructed for WDS transmission. The wireless AP/Router will
reconstruct the frame format upon receival and transmission using the criteria of the
receiving and forwarding port location and whether it is Ethernet or wireless in type.
Note: The wireless AP/Router does not support the spanning tree algorithm. WDS links
should be configured appropriately to avoid causing loops on the network.
Up to four WDS links can be specified for each unit in the WDS network.
The WDS link can be configured in the following combinations:
1.
All units are configured as Gateway Mode
2.
Units can be configured as Gateway Mode and Bridge Mode combinations.
(ex: 2 units for Gateway Mode and 2 units for Bridge Mode)
3.
All units are configured as Bridge Mode
When both units are set to Gateway Mode, be sure to check these settings:
• Be sure each unit is configured with a different LAN IP address.
• Be sure that only one unit has Internet access on its WAN port.
• Be sure the DHCP server is enabled only on one unit. If one unit is providing
Internet access, enable the DHCP server on that unit.
Note: WDS Settings only apply to WLAN1. WLAN2 is pre-configured to Bridge mode
unless WLAN1 is configured to act as a bridge, in which case WLAN2 is disabled.

System Configuration
Figure 5-16. WDS Settings
WDS Setting — Configures WDS related parameters. Up to four MAC addresses
can be specified for each unit in the WDS network. WDS links may either be
manually configured (Bridge and Repeater modes) or auto-discovered (Lazy mode).
• WDS Mode – Selects the WDS mode of WLAN1. (Options: Disable/Lazy/Bridge/
Repeater. Default: Disable)
- Disable: WDS is disabled.
- Lazy: Operates in an automatic mode that detects and learns WDS peer
addresses from received WDS four-address format frame packets, without the
need to configure a WDS MAC list entry. This feature allows the wireless AP/
Router to associate with other wireless AP/Routers in the network and use their
WDS MAC list. In Lazy mode the wireless AP/Router sends a beacon.
- Bridge: Operates as a standard bridge that forwards traffic between WDS links
(links that connect to other AP/wireless bridges, or units in Repeater or Lazy
mode) and an Ethernet port. Only data destined for stations which are known to
be on the peer Ethernet link, multicast data or data with unknown destinations,
need to be forwarded through the WDS link. The Bridge mode does not transmit
a beacon, unlike the other three modes. In this mode the wireless AP/Router
may also function as a repeater.
Note: Enabling “Bridge” mode disables WLAN2.
- Repeater: Operates as a wireless repeater, extending the range for remote
wireless clients and connecting them to an AP connected to the wired network.
WDS peers must be registered with the wireless AP/Router. Repeater mode
also supports the dual capability of the VAP functioning as an AP. In this mode,
traffic is not forwarded to the Ethernet port from the radio interface. In Repeater
mode the wireless AP/Router transmits a beacon.
Note: WDS settings may only be configured for WLAN1, See “Wi-Fi Protected Setup
(WPS)” on page 5-35. WLAN2 only operates as an access point service.
Note: Configuring WLAN1 to operate in WDS “Bridge” mode automatically disables
WLAN2.

HT Physical Mode Settings
Figure 5-17. HT Physical Mode Settings
• HT Operation Mode – Packets from 802.11n clients are referred to as High
Throughput (HT) Greenfield packets, in other words packets that can be
transmitted at rates of up to 300 Mbps assuming that HT Channel Bandwidth is set
to 20/40Mhz, see HT Channel Bandwidth next page.
Note: Some 802.11n wireless clients may be capable of transmission rates of up to
600 Mbps, however the wireless AP/Router will only be able to connect to them at
a maximum transmission rate of 300 Mbps.
802.11b/g packets are referred to as non-HT packets, being transmitted at lower
throughput rates. HT mixed format frames contain a preamble compatible with the
non-HT receivers. HT Greenfield frames do not contain a non-HT compatible part.
Support for HT Greenfield format is optional. An HT station that does not support
the reception of an HT Greenfield format frame must be able to detect that an HT
Greenfield format frame is an HT transmission (as opposed to a non-HT
transmission). In this case the receiver must decode the high throughput signal
(HT-SIG) in the packet header and determine if the HT-SIG cyclic redundancy
check (CRC) passes. (Default: Mixed)
• HT Channel Bandwidth – The wireless AP/Router provides a channel bandwidth
of 40 MHz by default giving an 802.11g connection speed of 108 Mbps (sometimes
referred to as Turbo Mode) and a 802.11n connection speed of up to 300 Mbps.
Setting the HT Channel Bandwidth to 20 MHz slows connection speed for 802.11g
and 802.11n to 54 Mbps and 74 Mbps respectively and ensures backward
compliance for slower 802.11b devices. (Default: 20/40MHz)
• Guard Interval – The guard interval between symbols helps receivers overcome
the effects of multipath delays. When you add a guard time, the back portion of
useful signal time is copied and appended to the front. (Default: Auto)
5-21

System Configuration
• MCS – The Modulation and Coding Scheme (MCS) is a value that determines the
modulation, coding and number of spatial channels. (Options: value [range] = 0~7
(1 Tx Stream), 8~15 (2 TxStream), 32 and auto (33). Default: auto)
• Reverse Direction Grant (RDG) – When enables Reverse Direction Grant, the
wireless AP/Router can reduce the transmitted data packet collision by using the
reverse direction protocol. During TXOP (Transmission Opportunity) period, the
receiver could use remaining transmission time to transmit data to a sender. The
RDG improves transmission performance and scalability in a wireless
environment.
• Extension Channel – When 20/40MHz channel bandwidth has been set, the
extension channel option will be enabled. The extension channel will allow you to
get extra bandwidth. (Options: 2417MHz/Channel 2, 2457MHz/Channel 10.
Default: 2457MHz/Channel 10.)
• Aggregate MSDU (A-MSDU) – This option enables Mac Service Data Unit
(MSDU) aggregation. (Default: Disable)
• Auto Block ACK – Select to block ACK (Acknowledge Number) or not during data
transferring.
• Decline BA Request – Select to reject peer BA-Request or not.

• BG Protection – Enables a backward
compatible protection system for
802.11b clients. There are three modes.
(Default: Auto):
- Auto: The wireless AP/Router enables
its protection mechanism for 802.11b
clients when they are detected in the network. When 802.11b clients are not
detected, the protection mechanism is disabled.
- On: Forces the unit to always use protection for 802.11b clients, whether they
are detected in the network or not.
- Off: Forces the unit to never use protection for 802.11b clients. This prevents
802.11b clients from connecting to the network.
Note: Enabling “On” b/g Protection can slow throughput for 802.11g/n clients by as
much as 50%.

System Configuration
• Beacon Interval – The rate at which beacon signals are transmitted from the
access point. The beacon signals allow wireless clients to maintain contact with the
access point. They may also carry power-management information. (Range:
20-999 TUs; Default: 100 TUs)
• Data Beacon Rate (DTIM) – The rate at which stations in sleep mode must wake
up to receive broadcast/multicast transmissions. Known also as the Delivery Traffic
Indication Map (DTIM) interval, it indicates how often the MAC layer forwards
broadcast/multicast traffic, which is necessary to wake up stations that are using
Power Save mode. The default value of 2 indicates that the access point will save
all broadcast/multicast frames for the Basic Service Set (BSS) and forward them
after every second beacon. Using smaller DTIM intervals delivers broadcast/
multicast frames in a more timely manner, causing stations in Power Save mode
to wake up more often and drain power faster. Using higher DTIM values reduces
the power used by stations in Power Save mode, but delays the transmission of
broadcast/multicast frames. (Range: 1-255 beacons; Default: 1 beacon)
• Fragment Threshold – Configures the minimum packet size that can be
fragmented when passing through the access point. Fragmentation of the PDUs
(Package Data Unit) can increase the reliability of transmissions because it
increases the probability of a successful transmission due to smaller frame size. If
there is significant interference present, or collisions due to high network utilization,
try setting the fragment size to send smaller fragments. This will speed up the
retransmission of smaller frames. However, it is more efficient to set the fragment
size larger if very little or no interference is present because it requires overhead
to send multiple frames. (Range: 256-2346 bytes; Default: 2346 bytes)
• RTS Threshold – Sets the packet size threshold at which a Request to Send
(RTS) signal must be sent to a receiving station prior to the sending station starting
communications. The access point sends RTS frames to a receiving station to
negotiate the sending of a data frame. After receiving an RTS frame, the station
sends a CTS (clear to send) frame to notify the sending station that it can start
sending data. If the RTS threshold is set to 0, the access point always sends RTS
signals. If set to 2347, the access point never sends RTS signals. If set to any other
value, and the packet size equals or exceeds the RTS threshold, the RTS/CTS
(Request to Send / Clear to Send) mechanism will be enabled. The access points
contending for the medium may not be aware of each other. The RTS/CTS
mechanism can solve this “Hidden Node Problem.” (Range: 0-2347 bytes)
• TX Power – Adjusts the power of the radio signals transmitted from the access
point. The higher the transmission power, the farther the transmission range.
Power selection is not just a trade off between coverage area and maximum
supported clients. You also have to ensure that high-power signals do not interfere
with the operation of other radio devices in the service area.
• Short Preamble – Enables the length of the signal preamble that is used at the
start of a data transmission. (Default: Disable)
5-24
5
Wireless Settings
• Short Slot – Sets the basic unit of time the wireless AP/Router’s uses for
calculating waiting times before data is transmitted. Enabling a short slot time can
increase data throughput on the wireless AP/Router, but requires that all clients
can support a short slot time (that is, 802.11g-compliant clients must support a
short slot time). (Default: Enable)
• Tx Burst – Enables data transmission bursting to boost throughput for high data
transmissions. (Default: Enable)
• Pkt_aggregation – Enables grouping together of some packets and sending them
together to boost bandwidth. (Default: Enable)
Configuring Wi-Fi Multimedia
Wireless networks offer an equal opportunity for all devices to transmit data from
any type of application. Although this is acceptable for most applications, multimedia
applications (with audio and video) are particularly sensitive to the delay and
throughput variations that result from this equal opportunity wireless access method.
For multimedia applications to run well over a wireless network, a Quality of Service
(QoS) mechanism is required to prioritize traffic types and provide an enhanced
opportunity wireless access method. The access point implements QoS using the
Wi-Fi Multimedia (WMM) standard. Using WMM, the access point is able to prioritize
traffic and optimize performance when multiple applications compete for wireless
network bandwidth at the same time. WMM employs techniques that are a subset of
the developing IEEE 802.11e QoS standard and it enables the access point to inter
operate with both WMM enabled clients and other devices that may lack any WMM
functionality.
Figure 5-20. Wi-Fi Multimedia Settings
• WMM Capable – Wi-Fi Multimedia (WMM), also known as Wireless Multimedia
Extensions (WME), is a Wi-Fi Alliance interoperability certification. It provides basic
Quality of Service (QoS) features for IEEE 802.11 wireless network. Enabling
WMM support provides prioritization of Wi-Fi data packets on four categories
voice, video, best effort, and background. (Default: Enabled)
5-25

System Configuration
• APSD Capable – Auto Power Save Delivery is used for saving power
consumption. APSD allows a longer beacon interval until the traffic arrives.
(Default: Disable., See “Beacon Interval” on page 5-24)
• DLS Capable – The Direct Link Setup (DLS) allows all clients transfer data more
effectively. When enables DLS, the wireless AP/Router will all clients on this unit to
establish directly connection and speed up the data transmission, especially for
multimedia data files. (Default: Disable)
• WMM Parameters – Display the WMM Parameters.
Access Categories – WMM defines four access categories (ACs): voice, video,
best effort, and background. These categories correspond to traffic priority levels
and are mapped to IEEE 802.1D priority tags (see Table 5-1). The direct mapping of
the four ACs to 802.1D priorities is specifically intended to facilitate inter operability
with other wired network QoS policies. While the four ACs are specified for specific
types of traffic, WMM allows the priority levels to be configured to match any
network-wide QoS policy. WMM also specifies a protocol that access points can use
to communicate the configured traffic priority levels to QoS-enabled wireless clients.
Table 5-2. WMM Access Categories
Access Category WMM Designation Description
802.1D Tags
AC_VO (AC3)

Highest priority, minimum delay. Time-sensitive
data such as VoIP (Voice over IP) calls.

AC_VI (AC2)
Video
High priority, minimum delay. Time-sensitive data 5, 4
such as streaming video.
AC_BE (AC0)

Data only affected by long delays. Data from
applications or devices that lack QoS capabilities.
AC_BK (AC1)
Background
Lowest priority. Data with no delay or throughput 2, 1
requirements, such as bulk data transfers.
WMM Operation — WMM uses traffic priority based on the four ACs; Voice, Video,
Best Effort, and Background. The higher the AC priority, the higher the probability
that data is transmitted. When the access point forwards traffic, WMM adds data
packets to four independent transmit queues, one for each AC, depending on the
802.1D priority tag of the packet. Data packets without a priority tag are always
added to the Best Effort AC queue. From the four queues, an internal “virtual”
collision resolution mechanism first selects data with the highest priority to be
granted a transmit opportunity. Then the same collision resolution mechanism is
used externally to determine which device has access to the wireless medium.

Figure 5-21. WMM Parameters
WMM Acknowledge Policy – By default, all wireless data transmissions require the
sender to wait for an acknowledgement from the receiver. WMM allows the
acknowledgement wait time to be turned off for each Access Category (AC).
Although this increases data throughput, it can also result in a high number of errors
when traffic levels are heavy. (Default: Acknowledge)
WMM BSS Parameters – These parameters apply to the wireless clients.
WMM AP Parameters – These parameters apply to the access point.
• logCWMin (Minimum Contention Window) – The initial upper limit of the random
backoff wait time before wireless medium access can be attempted. The initial wait
time is a random value between zero and the CWMin value. Specify the CWMin
value in the range 0-15 microseconds. Note that the CWMin value must be equal
or less than the CWMax value.
• logCWMax (Maximum Contention Window) – The maximum upper limit of the
random backoff wait time before wireless medium access can be attempted. The
contention window is doubled after each detected collision up to the CWMax value.
Specify the CWMax value in the range 0-15 microseconds. Note that the CWMax
value must be greater or equal to the CWMin value.
• AIFS (Arbitration Inter-Frame Space) – The minimum amount of wait time before
the next data transmission attempt. Specify the AIFS value in the range
0-15 microseconds.
5-27

System Configuration
• TXOP Limit (Transmit Opportunity Limit) – The maximum time an AC transmit
queue has access to the wireless medium. When an AC queue is granted a
transmit opportunity, it can transmit data for a time up to the TxOpLimit. This data
bursting greatly improves the efficiency for high data-rate traffic. Specify a value in
the range 0-65535 microseconds.
• Admission Control – The admission control mode for the access category. When
enabled, clients are blocked from using the access category. (Default: Disable)
WLAN Security
The wireless AP/Router’s wireless interface is configured by default as an “open
system,” which broadcasts a beacon signal including the configured SSID. Wireless
clients with a configured SSID of “ANY” can read the SSID from the beacon, and
automatically set their SSID to allow immediate connection to the wireless network.
To improve wireless network security, you have to implement two main functions:
• Authentication – It must be verified that clients attempting to connect to the
network are authorized users.
• Traffic Encryption – Data passing between the unit and clients must be protected
from interception and eavesdropping.
For a more secure network, the wireless AP/Router can implement one or a
combination of the following security mechanisms:
• Wired Equivalent Privacy (WEP)
• IEEE 802.1X
• Wi-Fi Protected Access (WPA) or WPA2
The security mechanisms that may be employed depend on the level of security
required, the network and management resources available, and the software
support provided on wireless clients. Click on “Wireless Settings,” followed by
“Security”.
Security
The wireless AP/Router supports two virtual access point (VAP) interfaces referred
to as WLAN1 and WLAN2. Each VAP functions as a separate access point, and can
be configured with its own security settings.

(WLAN1/WLAN2 Defaults: Open)
5-29
5
System Configuration
- Open: Open-system authentication accepts any client attempting to connect the
wireless AP/Router without verifying its identity. In this mode the default
encryption type is &quot;None.&quot;
- Shared: The shared-key approach uses Wired Equivalent Privacy (WEP) to
verify client identity by distributing a shared key to clients before attempting
authentication.
- WEP Auto: Allows WLAN clients to associate using Open-WEP (uses WEP for
encryption only) or Shared-WEP (uses WEP for authentication and encryption).
If enabled, you must configure at least one key for the VAP interface and all its
clients. Wired Equivalent Privacy (WEP) provides a basic level of security,
preventing unauthorized access to the network and encrypting data
transmitted between wireless clients and the wireless AP/Router. WEP uses
static shared keys (fixed-length hexadecimal or alphanumeric strings) that are
manually distributed to all clients that want to use the network.
5-30
Wireless Settings
5
- WPA-PSK or WPA2-PSK or WPA-PSK/WPA2-PSK: The WPA or WPA2 mode
uses a common password phrase, called a Pre-Shared Key, that must be
manually distributed to all clients that want to connect to the network. Specify a
key as an easy-to-remember form of letters and numbers. The WPA Preshared
Key can be input as ASCII string (8-63 characters) or Hexadecimal format
(length is 64). All wireless clients must be configured with the same key to
communicate with the VAP interface.
- WPA2: The WPA Enterprise mode uses IEEE 802.1X as its basic framework for
user authentication and dynamic key management. IEEE 802.1X access
security uses Extensible Authentication Protocol (EAP) and requires a
configured RADIUS authentication server to be accessible in the enterprise
network. If you select WPA or WPA2 Enterprise mode, be sure to configure the
RADIUS settings. See “RADIUS” on page 5-34 for more information.
5-31
5
System Configuration
- WPA or WPA1/WPA2: Defines a transitional mode of operation for networks
moving from WPA security to WPA2. WPA1/WPA2 Enterprise Mode allows both
WPA1 and WPA2 clients to associate to a common SSID interface. In WPA1/
WPA2 mixed mode, the unicast encryption cipher (TKIP or AES-CCMP) is
negotiated for each client. The access point advertises its supported encryption
ciphers in beacon frames and probe responses. WPA1 and WPA2 clients select
the cipher they support and return the choice in the association request to the
access point. For mixed-mode operation, the cipher used for broadcast frames
is always TKIP. WEP encryption is not allowed.
- 802.1x: IEEE 802.1X is a standard framework for network access control that
uses a central RADIUS server for user authentication. This control feature
prevents unauthorized access to the network by requiring an 802.1X client
application to submit user credentials for authentication. The 802.1X standard
uses the Extensible Authentication Protocol (EAP) to pass user credentials
(either digital certificates, user names and passwords, or other) from the client
to the RADIUS server. Client authentication is then verified on the RADIUS
server before the access point grants client access to the network.

- None: Disables data encryption.
- WEP: Selects WEP keys for data encryption.
- TKIP: Uses Temporal Key Integrity Protocol (TKIP) keys for encryption. WPA
specifies TKIP as the data encryption method to replace WEP. TKIP avoids the
problems of WEP static keys by dynamically changing data encryption keys.
- AES: Uses Advanced Encryption Standard (AES) keys for encryption. WPA2
uses AES Counter-Mode encryption with Cipher Block Chaining Message
Authentication Code (CBC-MAC) for message integrity. The AES
Counter-Mode/CBCMAC Protocol (AES-CCMP) provides extremely robust data
confidentiality using a 128-bit key. Use of AES-CCMP encryption is specified as
a standard requirement for WPA2. Before implementing WPA2 in the network,
be sure client devices are upgraded to WPA2-compliant hardware.
- TKIP/AES: Uses either TKIP or AES keys for encryption. WPA/WPA2 mixed
modes allow both WPA and WPA2 clients to associate to a common SSID
interface. In mixed mode, the unicast encryption cipher (TKIP or AES-CCMP) is
negotiated for each client.

RADIUS
Remote Authentication Dial-in User Service (RADIUS) is an authentication protocol
that uses software running on a central server to control access to RADIUS-aware
devices on the network. An authentication server contains a database of user
credentials for each user that requires access to the network.
A RADIUS server must be specified for the access point to implement IEEE 802.1X
network access control and Wi-Fi Protected Access (WPA) wireless security.
Click “WLAN1/WLAN2 Security” and be sure that an ‘Enterprise” mode is selected.
Note: This guide assumes that you have already configured RADIUS server(s) to

Wi-Fi Protected Setup (WPS)
Wi-Fi Protected Setup (WPS) is designed to ease installation and activation of
security features in wireless networks. WPS has two basic modes of operation,
Push-button Configuration (PBC) and Personal Identification Number (PIN). The
WPS PIN setup is optional to the PBC setup and provides more security. The WPS
button on the wireless AP/Router can be pressed at any time to allow a single device
to easily join the network.

• WPS Mode – Selects between methods of broadcasting the WPS beacon to
network clients wanting to join the network:
- PIN: The wireless AP/Router, along with other WPS devices, such as notebook
PCs, cameras, or phones, all come with their own eight-digit PIN code. When
one device, the WPS enrollee, sends a PIN code to the wireless AP/Router, it
becomes the WPS registrar. After configuring PIN-Code information you must
press “Apply” to send the beacon, after which you have up to two minutes to
activate WPS on devices that need to join the network.
- PBC: This has the same effect as pressing the physical WPS button that is
located on the front of the wireless AP/Router. After checking this option and
clicking “Apply” you have up to two minutes to activate WPS on devices that
need to join the network.

System Configuration
MAC/IP/Port Filtering
MAC/IP/Port filtering restricts connection parameters to limit the risk of intrusion and
defends against a wide array of common hacker attacks. IP/Port filtering allows the
unit to permit, deny or proxy traffic through its MAC addresses, IP addresses and
ports.
The wireless AP/Router allows you define a sequential list of permit or deny filtering
rules (up to 32). This device tests ingress packets against the filter rules one by one.
A packet will be accepted as soon as it matches a permit rule, or dropped as soon
as it matches a deny rule. If no rules match, the packet is either accepted or dropped
depending on the default policy setting.

conferencing, may not function properly behind the wireless AP/Router's firewall. By
specifying a Demilitarized Zone (DMZ) host, the PC's TCP ports are completely
exposed to the Internet, allowing open two-way communication. The host PC should
be assigned a static IP address (which is mapped to its MAC address) and this must
be configured as the DMZ IP address.

Everyone is permitted to copy and distribute verbatim copies of this license
document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your freedom to share
and change it. By contrast, the GNU General Public License is intended to
guarantee your freedom to share and change free software--to make sure the
software is free for all its users. This General Public License applies to most of the
Free Software Foundation's software and to any other program whose authors
commit to using it. (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.) You can apply it to your programs,
too.
When we speak of free software, we are referring to freedom, not price. Our General
Public Licenses are designed to make sure that you have the freedom to distribute
copies of free software (and charge for this service if you wish), that you receive
source code or can get it if you want it, that you can change the software or use
pieces of it in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid anyone to deny you
these rights or to ask you to surrender the rights. These restrictions translate to
certain responsibilities for you if you distribute copies of the software, or if you
modify it.
For example, if you distribute copies of such a program, whether gratis or for a fee,
you must give the recipients all the rights that you have. You must make sure that
they, too, receive or can get the source code. And you must show them these terms
so they know their rights.

License Information
We protect your rights with two steps: (1) copyright the software, and (2) offer you
this license which gives you legal permission to copy, distribute and/or modify the
software.
Also, for each author's protection and ours, we want to make certain that everyone
understands that there is no warranty for this free software. If the software is
modified by someone else and passed on, we want its recipients to know that what
they have is not the original, so that any problems introduced by others will not
reflect on the original authors' reputations.
Finally, any free program is threatened constantly by software patents. We wish to
avoid the danger that redistributors of a free program will individually obtain patent
licenses, in effect making the program proprietary. To prevent this, we have made it
clear that any patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and modification follow.
GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING,
DISTRIBUTION AND MODIFICATION
1.
This License applies to any program or other work which contains a notice
placed by the copyright holder saying it may be distributed under the terms of
this General Public License. The &quot;Program&quot;, below, refers to any such program
or work, and a &quot;work based on the Program&quot; means either the Program or any
derivative work under copyright law: that is to say, a work containing the
Program or a portion of it, either verbatim or with modifications and/or
translated into another language. (Hereinafter, translation is included without
limitation in the term &quot;modification&quot;.) Each licensee is addressed as &quot;you&quot;.
Activities other than copying, distribution and modification are not covered by
this License; they are outside its scope. The act of running the Program is not
restricted, and the output from the Program is covered only if its contents
constitute a work based on the Program (independent of having been made by
running the Program). Whether that is true depends on what the Program does.
2.
You may copy and distribute verbatim copies of the Program's source code as
you receive it, in any medium, provided that you conspicuously and
appropriately publish on each copy an appropriate copyright notice and
disclaimer of warranty; keep intact all the notices that refer to this License and
to the absence of any warranty; and give any other recipients of the Program a
copy of this License along with the Program.
You may charge a fee for the physical act of transferring a copy, and you may at
your option offer warranty protection in exchange for a fee.
3.
C-2
You may modify your copy or copies of the Program or any portion of it, thus
forming a work based on the Program, and copy and distribute such
modifications or work under the terms of Section 1 above, provided that you
also meet all of these conditions:
The GNU General Public License
C
a). You must cause the modified files to carry prominent notices stating that
you changed the files and the date of any change.
b). You must cause any work that you distribute or publish, that in whole or in
part contains or is derived from the Program or any part thereof, to be
licensed as a whole at no charge to all third parties under the terms of this
License.
c).
If the modified program normally reads commands interactively when run,
you must cause it, when started running for such interactive use in the
most ordinary way, to print or display an announcement including an
appropriate copyright notice and a notice that there is no warranty (or else,
saying that you provide a warranty) and that users may redistribute the
program under these conditions, and telling the user how to view a copy of
this License. (Exception: if the Program itself is interactive but does not
normally print such an announcement, your work based on the Program is
not required to print an announcement.)
These requirements apply to the modified work as a whole. If identifiable
sections of that work are not derived from the Program, and can be reasonably
considered independent and separate works in themselves, then this License,
and its terms, do not apply to those sections when you distribute them as
separate works. But when you distribute the same sections as part of a whole
which is a work based on the Program, the distribution of the whole must be on
the terms of this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest your rights to
work written entirely by you; rather, the intent is to exercise the right to control
the distribution of derivative or collective works based on the Program.
In addition, mere aggregation of another work not based on the Program with
the Program (or with a work based on the Program) on a volume of a storage or
distribution medium does not bring the other work under the scope of this
License.
4.
You may copy and distribute the Program (or a work based on it, under Section
2) in object code or executable form under the terms of Sections 1 and 2 above
provided that you also do one of the following:
a). Accompany it with the complete corresponding machine-readable source
code, which must be distributed under the terms of Sections 1 and 2 above
on a medium customarily used for software interchange; or,
b). Accompany it with a written offer, valid for at least three years, to give any
third party, for a charge no more than your cost of physically performing
source distribution, a complete machine-readable copy of the
corresponding source code, to be distributed under the terms of Sections 1
and 2 above on a medium customarily used for software interchange; or,
C-3
C
License Information
c).
Accompany it with the information you received as to the offer to distribute
corresponding source code. (This alternative is allowed only for
noncommercial distribution and only if you received the program in object
code or executable form with such an offer, in accord with Subsection b
above.)
The source code for a work means the preferred form of the work for making
modifications to it. For an executable work, complete source code means all the
source code for all modules it contains, plus any associated interface definition
files, plus the scripts used to control compilation and installation of the
executable. However, as a special exception, the source code distributed need
not include anything that is normally distributed (in either source or binary form)
with the major components (compiler, kernel, and so on) of the operating
system on which the executable runs, unless that component itself
accompanies the executable.
If distribution of executable or object code is made by offering access to copy
from a designated place, then offering equivalent access to copy the source
code from the same place counts as distribution of the source code, even
though third parties are not compelled to copy the source along with the object
code.
5.
You may not copy, modify, sublicense, or distribute the Program except as
expressly provided under this License. Any attempt otherwise to copy, modify,
sublicense or distribute the Program is void, and will automatically terminate
your rights under this License. However, parties who have received copies, or
rights, from you under this License will not have their licenses terminated so
long as such parties remain in full compliance.
6.
You are not required to accept this License, since you have not signed it.
However, nothing else grants you permission to modify or distribute the
Program or its derivative works. These actions are prohibited by law if you do
not accept this License. Therefore, by modifying or distributing the Program (or
any work based on the Program), you indicate your acceptance of this License
to do so, and all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
7.
Each time you redistribute the Program (or any work based on the Program),
the recipient automatically receives a license from the original licensor to copy,
distribute or modify the Program subject to these terms and conditions. You
may not impose any further restrictions on the recipients' exercise of the rights
granted herein. You are not responsible for enforcing compliance by third
parties to this License.
8.
If, as a consequence of a court judgment or allegation of patent infringement or
for any other reason (not limited to patent issues), conditions are imposed on
you (whether by court order, agreement or otherwise) that contradict the
conditions of this License, they do not excuse you from the conditions of this
License. If you cannot distribute so as to satisfy simultaneously your obligations
under this License and any other pertinent obligations, then as a consequence
C-4
The GNU General Public License
C
you may not distribute the Program at all. For example, if a patent license would
not permit royalty-free redistribution of the Program by all those who receive
copies directly or indirectly through you, then the only way you could satisfy
both it and this License would be to refrain entirely from distribution of the
Program.
If any portion of this section is held invalid or unenforceable under any
particular circumstance, the balance of the section is intended to apply and the
section as a whole is intended to apply in other circumstances.
It is not the purpose of this section to induce you to infringe any patents or other
property right claims or to contest validity of any such claims; this section has
the sole purpose of protecting the integrity of the free software distribution
system, which is implemented by public license practices. Many people have
made generous contributions to the wide range of software distributed through
that system in reliance on consistent application of that system; it is up to the
author/donor to decide if he or she is willing to distribute software through any
other system and a licensee cannot impose that choice.
This section is intended to make thoroughly clear what is believed to be a
consequence of the rest of this License.
9.
If the distribution and/or use of the Program is restricted in certain countries
either by patents or by copyrighted interfaces, the original copyright holder who
places the Program under this License may add an explicit geographical
distribution limitation excluding those countries, so that distribution is permitted
only in or among countries not thus excluded. In such case, this License
incorporates the limitation as if written in the body of this License.
10. The Free Software Foundation may publish revised and/or new versions of the
General Public License from time to time. Such new versions will be similar in
spirit to the present version, but may differ in detail to address new problems or
concerns.
Each version is given a distinguishing version number. If the Program specifies
a version number of this License which applies to it and &quot;any later version&quot;, you
have the option of following the terms and conditions either of that version or of
any later version published by the Free Software Foundation. If the Program
does not specify a version number of this License, you may choose any version
ever published by the Free Software Foundation.
11. If you wish to incorporate parts of the Program into other free programs whose
distribution conditions are different, write to the author to ask for permission.
For software which is copyrighted by the Free Software Foundation, write to the
Free Software Foundation; we sometimes make exceptions for this. Our
decision will be guided by the two goals of preserving the free status of all
derivatives of our free software and of promoting the sharing and reuse of
software generally.

Access Point
An internetworking device that seamlessly connects wired and wireless networks.
Access points attached to a wired network, support the creation of multiple radio
cells that enable roaming throughout a facility.
Advanced Encryption Standard (AES)
An encryption algorithm that implements symmetric key cryptography. AES provides
very strong encryption using a completely different ciphering algorithm to TKIP and
WEP.
Authentication
The process to verify the identity of a client requesting network access. IEEE 802.11
specifies two forms of authentication: open system and shared key.
Backbone
The core infrastructure of a network. The portion of the network that transports
information from one central location to another central location where it is unloaded
onto a local system.
Beacon
A signal periodically transmitted from the access point that is used to identify the
service set, and to maintain contact with wireless clients.
Broadcast Key
Broadcast keys are sent to stations using dynamic keying. Dynamic broadcast key
rotation is often used to allow the access point to generate a random group key and
periodically update all key-management capable wireless clients.
Dynamic Host Configuration Protocol (DHCP)
Provides a framework for passing configuration information to hosts on a TCP/IP
network. DHCP is based on the Bootstrap Protocol (BOOTP), adding the capability
of automatic allocation of reusable network addresses and additional configuration
options.

Encryption
Data passing between the access point and clients can use encryption to protect
from interception and evesdropping.
Ethernet
A popular local area data communications network, which accepts transmission
from computers and terminals.
File Transfer Protocol (FTP)
A TCP/IP protocol used for file transfer.
Hypertext Transfer Protocol (HTTP)
HTTP is a standard used to transmit and receive all data over the World Wide Web.
IEEE 802.11b
A wireless standard that supports wireless communications in the 2.4 GHz band
using Direct Sequence Spread Spectrum (DSSS). The standard provides for data
rates of 1, 2, 5.5, and 11 Mbps.
IEEE 802.11g
A wireless standard that supports wireless communications in the 2.4 GHz band
using Orthogonal Frequency Division Multiplexing (OFDM). The standard provides
for data rates of 6, 9, 11, 12, 18, 24, 36, 48, 54 Mbps. IEEE 802.11g is also
backward compatible with IEEE 802.11b.
IEEE 802.11n
A wireless standard that supports wireless communications in the 2.4 GHz band
using Orthogonal Frequency Division Multiplexing (OFDM). The standard provides
for data rates of 27, 54, 81, 108, 162, 216, 243, 270, 300 Mbps. IEEE 802.11n is also
backward compatible with IEEE 802.11b/g.
Infrastructure
An integrated wireless and wired LAN is called an infrastructure configuration.
Local Area Network (LAN)
A group of interconnected computer and support devices.
MAC Address
The physical layer address used to uniquely identify network nodes.
Network Time Protocol (NTP)
NTP provides the mechanisms to synchronize time across the network. The time
servers operate in a hierarchical-master-slave configuration in order to synchronize
local clocks within the subnet and to national time standards via wire or radio.
Glossary-2
Glossary
Open System
A security option which broadcasts a beacon signal including the access point’s
configured SSID. Wireless clients can read the SSID from the beacon, and
automatically reset their SSID to allow immediate connection to the nearest access
point.
Orthogonal Frequency Division Multiplexing (ODFM)
OFDM allows multiple users to transmit in an allocated band by dividing the
bandwidth into many narrow bandwidth carriers.
Repeater and Bridge
Repeater and bridge can provide an extended link to a remote access point from the
wired LAN. Access Point working in this mode could connect to another AP in
Access Point mode or Repeater and Bridge mode. Whenever there are two APs
having wireless link together (one in Access Point or Repeater and Bridge mode,
another using Repeater and Bridge mode), and also have wired link separately,
these two APs are also working as “bridging” for the two wired links.
Service Set Identifier (SSID)
An identifier that is attached to packets sent over the wireless LAN and functions as
a password for joining a particular radio cell; i.e., Basic Service Set (BSS).
Session Key
Session keys are unique to each client, and are used to authenticate a client
connection, and correlate traffic passing between a specific client and the access
point.
Shared Key
A shared key can be used to authenticate each client attached to a wireless network.
Shared Key authentication must be used along with the 802.11 Wireless Equivalent
Privacy algorithm.
Simple Network Time Protocol (SNTP)
SNTP allows a device to set its internal clock based on periodic updates from a
Network Time Protocol (NTP) server. Updates can be requested from a specific NTP
server, or can be received via broadcasts sent by NTP servers.
Temporal Key Integrity Protocol (TKIP)
A data encryption method designed as a replacement for WEP. TKIP avoids the
problems of WEP static keys by dynamically changing data encryption keys.
Trivial File Transfer Protocol (TFTP)
A TCP/IP protocol commonly used for software downloads.
Glossary-3
Glossary
Virtual Access Point (VAP)
Virtual AP technology multiplies the number of Access Points present within the RF
footprint of a single physical access device. With Virtual AP technology, WLAN users
within the device’s footprint can associate with what appears to be different access
points and their associated network services. All the services are delivered using a
single radio channel, enabling Virtual AP technology to optimize the use of limited
WLAN radio spectrum.
Wi-Fi Protected Access
WPA employs 802.1X as its basic framework for user authentication and dynamic
key management to provide an enhanced security solution for 802.11 wireless
networks.
Wired Equivalent Privacy (WEP)
WEP is based on the use of security keys and the popular RC4 encryption
algorithm. Wireless devices without a valid WEP key will be excluded from network
traffic.
WPA Pre-shared Key (WPA-PSK)
WPA-PSK can be used for small office networks with a limited number of users that
may not need a high level of security. WPA-PSK provides a simple security
implementation that uses just a pre-shared password for network access.
