Access Point Setup Guide
Once your Linksys access point is installed, choose which way you will manage it:
•
Remotely, using the Linksys cloud server, or
•
Locally, through a browser-based user interface
Setup to manage your access point with Linksys cloud
server
Step 1
Make sure the access point is powered on and connected with an ethernet cable to your network
with internet access. By factory default, the IP address is assigned by a DHCP server. If there is
no DHCP server in your network, the default IP address is 192.168.1.252/255.255.255.0.
Log in to the access point’s browser-based admin tool locally and click the Configure LAN
Settings link. Change the IP address or VLAN so the access point can access the internet.
If the indicator light is off, check that the AC power adapter, or PoE cable, is properly connected
on both ends.
Step 2
Enter http://Business.Linksys.com in a web browser to access the cloud dashboard. If you already
have a Linksys Small Business Cloud server account, log in.
6
If not, create an account by completing the on-screen forms. Then, register the access point at
the new account.
We'll send you a confirmation email. Click on the link and finish setting up your access point.
Setup to manage your access point locally with browserbased admin tool
Step1
Make sure the access point is powered on and connected with an ethernet cable to your network.
If the indicator light is off, check that the AC power adapter, or PoE cable, is properly connected
on both ends.
Step 2
Enter the IP address of your access point. By default, the IP address will be assigned by a DHCP
server (usually the network router). If there is no DHCP server on your network, the default IP
address is 192.168.1.252/255.255.255.0.
Step 3
Type in default username: admin, and password: admin.
Step 4
Click Login and disable the cloud management capability by clicking the Disable Cloud Manager

IGMP/MLD Snooping
IGMP
IGMP (Internet Group Management Protocol) is a communications
Snooping
protocol used by hosts and adjacent routers on IP networks to
establish multicast group memberships. IGMP is an integral part of IP
multicast.
IGMP snooping streamlines multicast traffic handling by examining
(snooping) IGMP membership report messages from interested
hosts, multicast traffic is limited to the subset of ports on which the
hosts reside.
IGMP snooping is enabled by default in the access point
The access point supports IGMPv1, IGMPv2 and IGMPv3 in IGMP
Snooping.
MLD Snooping
MLD (Multicast Listener Discovery) is a component of the Internet
Protocol Version 6 (IPv6) suite. MLD is used by IPv6 routers for
discovering multicast listeners on a directly attached link, much like
IGMP is used in IPv4.
Multicast Listener Discovery (MLD) Snooping provides multicast
containment by forwarding traffic only to those clients that have
MLD receivers for a specific multicast group (destination address).
The access point maintains the MLD group membership information
by processing MLD reports and generating messages so traffic can
be forwarded to ports receiving MLD reports.
MLD snooping is enabled by default in the access point
The access point supports MLDv1 and MLDv2 in MLD Snooping.

Guard Interval
Select the guard interval manually for Wireless-N
connections. The two options are Short (400
nanoseconds) and Long (800 nanoseconds). The
default is Auto.
CTS Protection
CTS (Clear-To-Send) Protection Mode boosts the
Mode
access point's ability to catch all Wireless-G
transmissions, but it severely decreases
performance. By default, CTS Protection Mode is
disabled, but the access point will automatically
enable this feature when Wireless-G devices are not
able to transmit to the access point in an environment
with heavy 802.11b traffic.
Beacon Interval
The access point transmits beacon frames at regular
intervals to announce the existence of the wireless
network. Enter the interval between the
transmissions of beacon frames. The value range is
between 40 and 1000 milliseconds and default is
100 milliseconds.
77
DTIM Interval
Enter the Delivery Traffic Information Map (DTIM)
period, an integer from 1 to 255 beacons. The default
is 1 beacon.
The DTIM message is an element included in some
beacon frames. It indicates which client stations,
currently sleeping in low-power mode, have data
buffered on the access point awaiting pickup.
The DTIM period that you specify indicates how often
the clients served by this WAP device should check
for buffered data still on the access point awaiting
pickup.
For example, if you enter 1, clients check for buffered
data on the access point at every beacon. If you enter
10, clients check on every 10th beacon.
RTS Threshold
Enter the Request to Send (RTS) Threshold value, an
integer from 1 to 2347. The default is 2347 octets.
The RTS threshold indicates the number of octets in a
Medium Access Control Protocol Data Unit (MPDU)
below which an RTS/CTS handshake is not performed.
Changing the RTS threshold can help control traffic
flow through the access point, especially one with a
lot of clients. If you specify a low threshold value, RTS
packets are sent more frequently, which consumes
more bandwidth and reduces the throughput of the
packet. However, sending more RTS packets can help
the network recover from interference or collisions
that might occur on a busy network, or on a network
experiencing electromagnetic interference.
78
Fragmentation
Enter the fragmentation threshold, an integer from
Threshold
256 to 2346. The default is 2346.
The fragmentation threshold is a way of limiting the
size of packets (frames) transmitted over the
network. If a packet exceeds the fragmentation
threshold you set, the fragmentation function is
activated and the packet is sent as multiple 802.11
frames.
If the packet being transmitted is equal to or less than
the threshold, fragmentation is not used. Setting the
threshold to the largest value (2,346 bytes, which is
the default) effectively disables fragmentation.
Fragmentation involves more overhead because of
the extra work of dividing up and reassembling of
frames it requires, and because it increases message
traffic on the network. However, fragmentation can
help improve network performance and reliability if
properly configured.
Output Power
Select the output power of the access point. If many
access points exist, lower power can reduce the
signal interference among them.
79

The remaining time of the authenticated session. The
timer starts when the client is authenticated. After
the time reaches zero, the client is de-authenticated.
If the value is fixed to 0, the session won't time out.
Measured in seconds.
Cluster
The cluster function provides a centralized method to administer and control wireless services
across multiple devices. When access points are clustered, you can view, deploy, configure, and
secure the wireless network as a single entity.
Note-Firmware version 1.1.0 or above support cluster feature. If your device has legacy
firmware installed, download the latest one from www.linksys.com/support.
The access points within a cluster must have the same management VLAN configured. A cluster
can support 16 LAPAC1200C/LAPAC1750C access points, as long as they are same model
number.
In each cluster, one access point must be manually configured as the master access point. There
can only be one master in a cluster. This master will propagate configuration information, such as
wireless settings, time settings etc. to the other team members within a cluster. Log in to the
master access point to change sharable parameter settings instead of slaves.
When firmware is upgraded on the master, all slaves within the same cluster will receive the
upgrade.
89

Note— If system detects there is one Master
already existed in the same cluster, the new
access point that likes to become master will be
assigned to slave automatically.
Slave—Enable the cluster function and assign the
access point to be the slave.
Note—When the cluster function is enabled, WDS
and workgroup bridge will be disabled
automatically.

91
Status
Disabled—Cluster function is disabled.
Active—Cluster function is enabled and master is active.
Active (Backup Master)—Cluster function is enabled and backup master
is active.
Inactive (Cannot reach the master)—Cluster function is enabled but it's
inactive because device cannot reach the master.
Member Number
Number of the members active in the cluster. If an access point joins the
cluster but is powered off or cannot reach the master, it is not counted.
Location (Optional)
Where the access point is physically located; for example, Reception.
Length is from 0 to 32 bytes.
Cluster Name
Name of the cluster for the LAP device to join; for example, “lab cluster”.
All access points with the same cluster name belong to the same
cluster. Length of this value is from 4 to 32 bytes and special
characters are allowed. This is a mandatory field if the cluster function
is turned on.
Backup Master
When an access point works as a cluster slave, it can be enabled as a
backup master. When master gets offline, it will take the role of master.
When the backup master begins to work, it will send advertisements
and slaves will send keep-alive and report sessions to it. When
shareable settings are modified in it, it will share them to all slaves.
When master gets online again, this backup master AP will stop the
master function and let original master AP take over master role.
92
Client Sessions
Go to Configuration > Cluster > Client Sessions to see the status of wireless clients within the
cluster.
The session is the period of time in which a user on a client device (station) with a unique MAC
address maintains a connection with the wireless network. The session begins when the WLAN
client logs on to the network, and the session ends when the WLAN client either logs off
intentionally or loses the connection for some other reason.
When one wireless client of Captive Portal roams from one access point to another in the same
cluster, it need not re-authenticate.

the client by the access point. Unit is Kbps.
Channel Management
Go to Configuration > Cluster > Channel Management to manage the channel assignments for
access points within a cluster.
When channel management is enabled, the access point automatically assigns radio channels
within a cluster. Auto channel assignment reduces mutual interference (or interference with other
access points outside of its cluster) and maximizes Wi-Fi bandwidth to help maintain efficient
communication over the wireless network.
94
Auto Channel

Appendix A - Troubleshooting
Overview
This chapter covers some common problems encountered while using the wireless access point,
and some possible solutions to them. If you follow the suggested steps and the wireless access
point still does not function properly, contact your dealer for further advice.
General Problems
I can't find new access point on my network.
Check the following:
•
The wireless access point is properly installed, LAN connections are OK, and it is powered
ON. Check the LEDs for system and port status.
•
Ensure that your PC and the wireless access point are on the same network segment. (If
you don't have a router, this must be the case.)
•
You can use the following method to determine the IP address of the wireless access
point, and then try to connect using the IP address, instead of the name.
To find the access point's IP address:
1. Open a MS-DOS Prompt or Command Prompt Window.
2. Use the Ping command to ping the wireless access point. Enter “ping” followed by the
default name of the wireless access point. Default name is “lap” followed by the last five
characters of device MAC address (e.g., ping lap964d6).
3. Check the output of the ping command to determine the IP address of the wireless access
point, as shown below.
If your PC uses a fixed (static) IP address, ensure that it is using an IP address that is in the
network segment (subnet) with the wireless access point. On Windows PCs, you can use Control
Panel > Network to check the properties for the TCP/IP protocol.
112
If there is no DHCP Server found, the wireless access point will roll back to an IP address and
mask of 192.168.1.252 and 255.255.255.0.
My PC can't connect to the LAN via the wireless access point.
Check the following:
•
The SSID and security settings on the PC match the settings on the access point.
•
On the PC, the wireless mode is set to Infrastructure.
•
If using the Access Control feature, the PC's name and address is in the Trusted Stations
list.
•
If using 802.1x mode, ensure the PC's 802.1x software is configured correctly. See
Appendix C (p. 120) for details of setup for the Windows XP 802.1x client. If using a
different client, refer to the vendor's documentation.
113
Appendix B - About Wireless LANs
Overview
Wireless networks have their own terms and jargon. You must understand many of these terms in
order to configure and operate a wireless LAN.
Wireless LAN Terminology
Modes
Wireless LANs can work in either of two (2) modes:
•
Ad-hoc
•
Infrastructure
Ad-hoc Mode
Ad-hoc Mode does not require an access point or a wired (Ethernet) LAN. Wireless stations, e.g.,
notebook PCs with wireless cards, communicate directly with each other.
Infrastructure Mode
In Infrastructure Mode, one or more access points are used to connect wireless stations, e.g.,
notebook PCs with wireless cards, to a wired (Ethernet) LAN. The wireless stations can then
access all LAN resources.
Note—Access points can only function in Infrastructure Mode, and can communicate only with
wireless stations that are set to Infrastructure Mode.
SSID/ESSID
BSS/SSID
A group of wireless stations and a single access point, all using the same ID (SSID), form a Basic
Service Set (BSS).
Using the same SSID is essential. Devices with different SSIDs are unable to communicate with
each other.
114
ESS/ESSID
A group of wireless stations, and multiple access points all using the same ID (ESSID), form an
Extended Service Set (ESS).
Different access points within an ESS can use different channels. To reduce interference, it is
recommended that adjacent access points use different channels.
As wireless stations are physically moved through the area covered by an ESS, they will
automatically change to the access point that has the least interference or best performance.
Channels
•
The wireless channel sets the radio frequency used for communication.
•
Access points use a fixed channel. You can select the channel used. This allows you to
choose a channel that provides the least interference and best performance. For USA and
Canada, the following channels are available:
-
2.4GHz:

-
•
to 2.462 GHz; 11 channels
5GHz:

5.180 to 5.240 GHz; 4 channels

5.745 to 5.825 GHz; 5 channels
When using multiple access points it is better if adjacent access points use different
channels to reduce interference. The recommended channel spacing between adjacent
access points is five channels, e.g., use Channels 1 and 6, or 6 and 11.
•
In Infrastructure Mode wireless stations normally scan all channels looking for an access
point. If more than one access point can be used, the one with the strongest signal is used.
(This can only happen within an ESS.)
•
If using Ad-hoc Mode (no access point) all wireless stations should be set to use the same
channel. However, most wireless stations will still scan all channels to see if there is an
existing Ad-hoc group they can join.
WEP
WEP (Wired Equivalent Privacy) is a standard for encrypting data before it is transmitted. This is
desirable because it is impossible to prevent snoopers from receiving any data which is
transmitted by your wireless stations. If the data is encrypted, it is meaningless unless the
receiver can decrypt it.
If WEP is used, the wireless stations and the wireless access point must have the same settings.
115
WPA-PSK
In WPA-PSK, like WEP, data is encrypted before transmission. WPA is more secure than WEP. The
PSK (pre-shared key) must be entered on each wireless station. The 256-bit encryption key is
derived from the PSK, and changes frequently.
WPA2-PSK
This is a further development of WPA-PSK, and offers even greater security, using the AES
(Advanced Encryption Standard) method of encryption. It should be used if possible.
WPA-Enterprise
This version of WPA requires a RADIUS server on your LAN to provide the client authentication
according to the 802.1X standard. Data transmissions are encrypted using the WPA standard.
If this option is used:
•
The access point must have a client login on the RADIUS server.
•
Each user must have a user login on the RADIUS server.
•
Each user's wireless client must support 802.1X and provide the login data when
required.
All data transmission is encrypted using the WPA standard. Keys are automatically generated, so
no key input is required.
WPA2-Enterprise
This version of WPA2 requires a RADIUS server on your LAN to provide the client authentication
according to the 802.1X standard. Data transmissions are encrypted using the WPA2 standard.
If this option is used:
•
The access point must have a client login on the RADIUS server.
•
Each user must have a user login on the RADIUS server.
•
Each user's wireless client must support 802.1X and provide the login data when
required.
All data transmission is encrypted using the WPA2 standard. Keys are automatically generated,
so no key input is required.
802.1x
This uses the 802.1X standard for client authentication, and WEP for data encryption. If possible,
you should use WPA-Enterprise instead, because WPA encryption is much stronger than WEP
encryption.
116
If this option is used:
•
The access point must have a client login on the RADIUS server.
•
Each user must have a user login on the RADIUS server.
•
Each user's wireless client must support 802.1X and provide the login data when
required.
•
All data transmission is encrypted using the WEP standard. You only have to select the
WEP key size; the WEP key is automatically generated.
117
Appendix C - PC and Server Configuration
Overview
All wireless stations need to have settings that match the wireless access point. These settings
depend on the mode in which the access point is being used.
•
If using WEP or WPA2-PSK, it is only necessary to ensure that each wireless station's
settings match those of the wireless access point, as described below.
•
For 802.1x modes, configuration is much more complex. The RADIUS server must be
configured correctly, and setup of each wireless station is also more complex.
Using WEP
For each of the following items, each wireless station must have the same settings as the wireless
access point.
Mode
On each PC, the mode must be set to Infrastructure.
SSID (ESSID)
This must match the value used on the wireless access point.
The default value is LinksysSMB24G for radio 1 and LinksysSMB5G for radio 2.
Note—The SSID is case sensitive.
Wireless
•
Each wireless station must be set to use WEP data encryption.
Security
•
The key size (64 bit, 128 bit) must be set to match the access point.
•
The key values on the PC must match the key values on the access point.
Note—One set of WEP keys is supported per radio.
118
Using WPA2-PSK
For each of the following items, each wireless station must have the same settings as the wireless
access point.
Mode
On each PC, the mode must be set to Infrastructure.
SSID (ESSID)
This must match the value used on the wireless access point.
The default value is LinksysSMB24G for radio 1 and
LinksysSMB5G for radio 2.
Note—The SSID is case sensitive.
Wireless
Security
On each client, wireless security must be set to WPA2-PSK.
•
The pre-shared key entered on the access point must
also be entered on each wireless client.
•
The encryption method (e.g. TKIP, AES) must be set to
match the access point.
Using WPA2-Enterprise
This is the most secure and most complex system.
WPA-Enterprise mode provides greater security and centralized management, but it is more
complex to configure.
Wireless Station Configuration
For each of the following, wireless stations must have the same settings as the wireless access
point.
Mode
On each PC, the mode must be set to Infrastructure.
SSID (ESSID)
This must match the value used on the wireless access point.
The default value is LinksysSMB24G for radio 1 and
LinksysSMB5G for radio 2.
Note—The SSID is case sensitive.
802.1x
Each client must obtain a certificate for authentication for
Authentication
the RADIUS server.
802.1x
Typically, EAP-TLS is used. This is a dynamic key system, so
Encryption
keys do NOT have to be entered on each wireless station.
You can also use a static WEP key (EAP-MD5). The wireless
access point supports both methods simultaneously.
119
RADIUS Server Configuration
If using WPA2-Enterprise mode, the RADIUS server on your network must be configured as
follows:
•
It must provide and accept certificates for user authentication.
•
There must be a client login for the wireless access point itself.
•
The wireless access point will use its default name as its client login name. (However, your
RADIUS server may ignore this and use the IP address instead.)
•
The Shared Key, set on the Security screen of the access point, must match the Shared
Secret value on the RADIUS server.
•
Encryption settings must be correct.
802.1x Server Setup (Windows 2000 Server)
This section describes using Microsoft Internet Authentication Server as the RADIUS server,
since it is the most common RADIUS server available that supports the EAP-TLS authentication

802.1x Client Setup on Windows XP
Windows XP ships with a complete 802.1x client implementation. If using Windows 2000, you can
install SP3 (Service Pack 3) to gain the same functionality.
If you don't have either of these systems, you must use the 802.1x client software provided with
your wireless adapter. Refer to your vendor's documentation for setup instructions.
The following instructions assume:
•
You are using Windows XP.
•
You are connecting to a Windows 2000 server for authentication.
•
You already have a login (User name and password) on the Windows 2000 server.
129
Client Certificate Setup
1. Connect to a network that doesn't require port authentication.
2. Start your Web browser. In the address box, enter the IP address of the Windows 2000
Server, followed by “/certsrv”, e.g., “http://192.168.0.2/certsrv”.
3. You will be prompted for a user name and password. Enter the User name and Password
assigned to you by your network administrator and click OK.
4. On the first screen (below), select Request a certificate, click Next.
130
5. Select User certificate request and select User Certificate, click Next.
6. Click Submit.
131
7. A message will be displayed, and the certificate will be returned to you.
Click Install this certificate.
8. You will receive a confirmation message. Click Yes.
9. Certificate setup is now complete.
132
802.1x Authentication Setup
1. Select Start > Control Panel > Network Connections.
2. Right-click on the Wireless Network Connection and select Properties.
3. Select the Authentication tab and ensure that Enable network access control using IEEE
802.1X is selected, and Smart Card or other Certificate is selected from the EAP type.
Encryption Settings
The encryption settings must match the access point on the wireless network you wish to join.
•
Windows XP will detect any available wireless networks, and allow you to configure each
network independently.
•
Your network administrator can advise you of the correct settings for each network.
802.1x networks typically use EAP-TLS. This is a dynamic key system, so there is no need
to enter key values.
133
Enabling Encryption
To enable encryption for a wireless network:
1. Click on the Wireless Networks tab.
2. Select the wireless network from the Available networks list and click Configure.
134
3. Select and enter the correct values, as advised by your Network Administrator.
For example, to use EAP-TLS, you would enable Data encryption, and click the checkbox
for the setting The key is provided for me automatically, as shown below.
4. Setup for Windows XP and 802.1x client is now complete.
Using 802.1x Mode (without WPA)
This is very similar to using WPA-Enterprise.
The only difference is that on your client, you must NOT enable the setting The key is provided for
me automatically.
135
Instead, you must enter the WEP key manually, ensuring it matches the WEP key used on the
access point.
Note—On some systems, the 64-bit WEP key is shown as 40-bit and the 128-bit WEP key is
shown as 104-bit. This difference arises because the key input by the user is 24 bits less than
the key size used for encryption.
