3.2.2 Wireless Setting
This Access Point supports AP, Station, Bridge, WDS and Universal Repeater modes.
“AP Mode” provides pure access point function. The simplest way to build up a
wireless LAN is to use “AP Mode”. “Station Mode” is used to let a network device
with only wired Ethernet function to have wireless LAN communication capability. It
provides both Ad Hoc and Infrastructure modes for the “Station Mode”. With
“Station-Ad Hoc mode”, it can let your network device join a wireless LAN with
peer-to-peer communication. With “Station-Infrastructure mode”, it can let your
network device join a wireless LAN through an access point. “AP Bridge Mode”
provides the function to bridge more than 2 wired Ethernet networks together by
wireless LAN. You can use two access points with “AP Bridge-Point to Point mode”
to bridge two wired Ethernet networks together. If you want to bridge more than two
wired Ethernet networks together, you have to use enough access points with “AP
Bridge-Point to Multi-Point mode”. An access point with “AP Bridge-Point to Point
mode” or “AP Bridge-Point to Multi-Point mode” can only be used to bridge wired
Ethernet networks together. It can’t accept connection from other wireless station at
the same time. If you want an access point to bridge wired Ethernet network and
provide connection service for other wireless station at the same time, you have to set
the access point to “AP Bridge-WDS mode”. Simply speaking, “AP Bridge-WDS
mode” function is the combination of “AP mode” and “AP Bridge-Point to MultiPoint mode”. “Universal Repeater Mode” provides the function to act as AP client
and AP at the same time. It can use AP client function to connect to a Root AP and
use AP function to service all wireless stations within its coverage. All the stations
within the coverage of this access point can be bridged to the Root AP. “Universal
Repeater Mode” is very convenient to extend the coverage of your wireless network.

You should assign Channel Number in “AP mode”, “Station-Ad Hoc
mode”, “AP Bridge-Point to Point mode”, “AP Bridge-Point to Multi-Point
mode” and “AP Bridge-WDS mode”, “Universal Repeater mode”.
MAC Address
If you want to bridge more than one wired Ethernet networks together
with wireless LAN, you have to set this access point to “AP Bridge-Point
to Point mode”, “AP Bridge-Point to Multi-Point mode” or “AP BridgeWDS mode”. You have to enter the MAC addresses of other access
points that join the bridging work.
WLAN BSSID
A BSSID is the MAC address of an access point (AP) in an infrastructure
mode BSS. If WLAN BSSID is left at the factory default (000000000000),
the station (client) will connect to any Access Point (AP) with the
specified ESSID. If there is more than one AP with the same ESSID, a
station (client) will connect to the AP with the strongest signal. If you want
to force a station to connect to a specific AP, then set the WLAN BSSID
to the MAC address of the desired AP.
WLAN MAC
In “Station-Ad Hoc mode”, “Station-Infrastructure mode” and “Universal
Repeater mode”, this device needs a WLAN MAC address to act as a
station to connect to another peer or Access Point (AP). If WLAN MAC =
000000000000 (factory default), then the device uses the factory
assigned MAC address. If you set the WLAN MAC to any other number,
the device will use the MAC address you have specified. You also can
click “Clone MAC” button to let this device copy the MAC address of the
PC you are using to configure this device. If the device is in one of the 3
modes above, and if the wired interface is connected to an Ethernet
interface on a router, then it is important to set the WLAN MAC to be
identical to the MAC address of the router interface.

result in bad performance.
RTS Threshold
When the packet size is smaller than the RTS threshold, the access point
will not use the RTS/CTS mechanism to send this packet.
Beacon Interval
The interval of time that this access point broadcast a beacon. Beacon is
used to synchronize the wireless network.
Data Rate
The “Data Rate” is the rate this access point uses to transmit data
packets. The access point will use the highest possible selected
transmission rate to transmit the data packets.
Preamble Type
Preamble type defines the length of CRC block in the frames during the
wireless communication. “Short Preamble” is suitable for high traffic
wireless network. “Long Preamble” can provide more reliable
communication.
Broadcast ESSID
If you enable “Broadcast ESSID”, every wireless station located within
the coverage of this access point can discover this access point easily. If
you are building a public wireless network, enabling this feature is
recommended. Disabling “Broadcast ESSID” can provide better security.
IAPP
If you enable “IAPP”, the access point will automatically broadcast
information of associated wireless stations to its neighbors. This will help
wireless station roaming smoothly between access points. If you have
more than one access points in your wireless LAN and wireless stations
have roaming requirements, enabling this feature is recommended.
Disabling “IAPP” can provide better security.

2. What is Ad-hoc?
An Ad-hoc wireless LAN is a group of computers, each with a WLAN adapter,
connected as an independent wireless LAN.
3. What is Infrastructure?
An integrated wireless and wired LAN is called an Infrastructure configuration.
4. What is BSS ID?
A group of wireless stations and an Access Point compose a Basic Service Set
(BSS). Computers in a BSS must be configured with the same BSSID.
5. What is ESSID?
An Infrastructure configuration could also support roaming capability for mobile
workers. More than one BSS can be configured as an Extended Service Set (ESS).
Users within an ESS could roam freely between BSSs while maintaining a
continuous connection to the wireless network stations and the Wireless LAN
Access Points.
6. Can data be intercepted while transmitting through the air?
WLAN features two-fold protection in security. On the hardware side, as with
Direct Sequence Spread Spectrum technology, it has the inherent scrambling
security feature. On the software side, the WLAN series offers the encryption
function (WEP, WPA, WPA2) to enhance security and access control.

Troubleshooting
7. What is WEP?
WEP stands for Wired Equivalent Privacy, a data privacy mechanism based on a
64(40)-bit shared key algorithm.
8. What is WPA?
WPA is an acronym for Wi-Fi Protected Access. It is a security protocol for
802.11 wireless networks. WPA can provide data protection with the use of
encryption and the use of access controls and user authentication.
9. What is WPA2?
In addition to WPA, WPA2 provides a stronger encryption mechanism through
Advanced Encryption Standard (AES).
10. What is a MAC Address?
The Media Access Control (MAC) address is a unique number assigned by the
manufacturer to any Ethernet networking device, such as a network adapter, that
allows the network to identify it at the hardware level. For all practical purposes,
this number is usually permanent. Unlike IP addresses, which can change every
time a computer logs on to the network, the MAC address of a device stays the
same, making it a valuable identifier for the network.
