Access Point Setup
Overview
This chapter describes the setup procedure to connect the wireless access point to your LAN,
and configure it as an access point for your wireless stations.
Wireless stations may also require configuration. For details, see Appendix C - Wireless
Station Configuration.
The wireless access point can be configured using a Web browser.
Setup using a Web Browser
Your browser must support JavaScript. The configuration program has been tested on the
following browsers:
•
Firefox 3.5 or later, Chrome 8 or later, Safari 5 or later
•
Internet Explorer 7 or later
Setup Procedure
Before starting setup, install the wireless access point on your LAN, as described earlier.
1.
2.
3.
4.
Locate the wireless access point’s default name on a label on the base or rear. The default
name will be lapxxxxx, where xxxxx is a set of the last 5 characters of your access point
MAC address. MAC address is available on the brown box label or product label.
Use a PC connected to your LAN, either by a wired connection or another access point.
Until the wireless access point is configured, establishing a wireless connection to it may
be not possible.
If your LAN contains a router or routers, ensure the PC used for configuration is on the
same LAN segment as the wireless access point.
Start your Web browser.
Enter the IP address of the wireless access point, as in this example, which uses the
wireless access point's default IP address:
http://192.168.1.252
At the login prompt, enter admin for the User name, and admin for the Password.
These are the default values. You should change the password.

Figure 1: Password Dialog
From the status screen menu configure for your environment. Details of these screens and
settings are described in the following sections of this chapter.
You may also wish to change the admin password on the User Accounts screen, accessed
from the Configuration menu.
Wireless stations must now be set to match the wireless access point. See Chapter 4 for
details.
If you can't connect:
It is likely that your PC’s IP address is incompatible with the wireless access
point’s IP address. This can happen if your LAN does not have a DHCP Server.
The default IP address of the wireless access point is 192.168.1.252, with a
network mask of 255.255.255.0.
If your PC’s IP address is not compatible with this, you must change your PC’s IP
address to an unused value in the range 192.168.1.1 ~ 192.168.1.254, with a
network mask of 255.255.255.0. See Appendix A - Troubleshooting for details for
this procedure.

system is not very strong.
•
WPA2-Personal - This is a further development of WPA-PSK, and offers even greater
security, using the AES (Advanced Encryption Standard) method. This method, sometimes called "Mixed Mode", allows clients to use either WPA-Personal (with TKIP) or
WPA2-Personal (with AES).
•
WPA2-Enterprise - 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 selected:
•
This access point must have a client login on the RADIUS Server.
•
Each user must authenticate on the RADIUS Server. This is usually done using digital
certificates.
22
•
•
Each user's wireless client must support 802.1x and provide the RADIUS authentication data when required.
•

and background. For an application to receive the benefits of WMM
QoS, both it and the client running that application have to have WMM
enabled. Legacy applications that do not support WMM and applications that do not require QoS are assigned to the best effort category,
which receives a lower priority than voice and video.
WMM is enabled by default.

Workgroup Bridge
Workgroup Bridge feature enables the access point to extend the accessibility of a remote network.
In Workgroup Bridge mode, the access point acts as a wireless station (STA) on the wireless LAN. It
can bridge traffic between a remote wired network and a wireless LAN.
When Workgroup Bridge is enabled, SSID configuration still works to provide wireless
services to clients.
All access points participating in Workgroup Bridge must have the identical settings for Radio

Band Steering
Band Steering
Enable or disable Band Steering function. Disabled by default.
Band Steering is a technology that detects whether the wireless
client is dual-band capable. If it is, band steering pushes the
client to connect to the less-congested 5 GHz network. It does
this by actively blocking the client’s attempts to connect with
the 2.4GHz network.
Isolation
Isolation between
SSIDs
Define whether to isolate traffic between SSIDs. If enabled,
wireless clients in different SSIDs cannot communicate with
each other. Enabled by default.

Wireless Radio
Select the desired radio from the list.
Radio 1 is for 2.4 GHz, and Radio 2 is for 5 GHz.
Worldwide Mode
(802.11d)
Worldwide Mode (802.11d) enables the access point to direct
connected wireless devices to radio settings specific to where in
the world the devices are in use.
43
Channel Bandwidth
You can select the channel bandwidth manually for Wireless-N
connections. When it is set to 20MHz, only 20MHz channel is
being used. When it is set to 40MHz, Wireless-N connections
will use 40MHz channel, but Wireless-B connections and
Wireless-G connections will still use 20MHz channel.
Select the designed channel bandwidth for the wireless radio.
•
20MHz - Select if you are not using any 802.11n wireless clients.
•
20/40MHz - Select if you are using both 802.11n and
non-802.11n wireless devices.
•
20/40/80MHz - Select if you are using 802.11ac,
802.11n and non-802.11n wireless devices.
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 Mode
CTS (Clear-To-Send) Protection Mode boosts the 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.
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.
44
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.
Fragmentation
Threshold
Enter the fragmentation threshold, an integer from 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.

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
Problem 1:
I can't find new access point on my network.
Solution 1:
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 a string with “lap” and the last 5 characters of device MAC address.
e.g.
ping lap97024
3. Check the output of the ping command to determine the IP address of
the wireless access point, as shown below.
Figure 45: Ping
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.
If there is no DHCP Server found, the wireless access point will roll back to
64
an IP address and mask of 192.168.1.252 and 255.255.255.0.
Problem 2:
My PC can't connect to the LAN via the wireless access point.
Solution 2:
Check the following:
•
The SSID and security settings on the PC match the settings on the
wireless 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 Chapter 4 for details of setup for the Windows XP
802.1x client. If using a different client, refer to the vendor's documentation.

Appendix B
About Wireless LANs
Overview
Wireless networks have their own terms and jargon. It is necessary to 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.
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.
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 SHOULD use different channels.
66
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.
This capability is called Roaming. (Access points do not have or require roaming capabilities.)
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:
2.412 to 2.462 GHz; 11 channels
5GHz:
•
5.180 to 5.240 GHz; 4 channels
•
5.745 to 5.825 GHz; 5 channels
•
If 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.
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.
67
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.
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.
68
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
Security
•
Each wireless station must be set to use WEP data encryption.
•
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:
On some systems, the key sizes may be shown as 40-bit and 104-bit
instead of 64-bit, 128-bit. This is because the key input by the user is 24
bits less than the key size used for encryption.
69
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.
70
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 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.
802.1x
Authentication
Each client must obtain a certificate for authentication for the RADIUS
server.
802.1x
Encryption
Typically, EAP-TLS is used. This is a dynamic key system, so 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.
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.
71
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 method.
The following services on the Windows 2000 Domain Controller (PDC) are also required.
•
dhcpd
•
dns
•
rras
•

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 that:
•
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.
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

Encryption Settings
The encryption settings must match the access point’s on the wireless network you wish to join.
•
Windows XP will detect any available wireless networks, and allow you to configure each
network independently.
85
•
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.
Enabling Encryption
To enable encryption for a wireless network, follow this procedure.
1. Click on the Wireless Networks tab.
Figure 69: Wireless Networks Screen
2.
3.
Select the wireless network from the Available Networks list, and click Configure.
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.
86
Figure 70: Properties Screen
Setup for Windows XP and 802.1x client is now complete.
87
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.
Instead, you must enter the WEP key manually, ensuring it matches the WEP key used on the
access point.
Figure 71: Properties Screen
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.
