CHAPTER 2 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:
•Firefox3.5orlater,Chrome8orlater,Safari5orlater
•InternetExplorer7orlater
Setup Procedure
Make sure device is powered on before you continue setup. If LED light is off,
check that AC power adapter, or PoE cable, is properly connected on both ends.
Access device’s browser-based setup:
1. Use the included cable to connect the access point to your network via a
network switch or router.
2. Open a web browser on a computer connected to your network. Enter the
IP address of your access point. By factory 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.
Note: Use a computer hardwired to the same network as your access point for
browser-based setup access. Access to browser-based setup via WiFi is disabled
by default.
3. Type in default username: “admin”, and password: “admin”.
4. Click Log in to launch the browser-based setup and follow the on-screen
instructions
Figure 1: Password Dialog
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. If there is no DHCP server in your network, the
access point will fall back to its default IP address: 192.168.1.252,
with a network mask of 255.255.255.0.
Or, 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 - Windows TCP/IP for details for this procedure.

•WEP - The 802.11b standard. Data is encrypted before transmission, but
the encryption 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.
• Each user’s wireless client must support 802.1x and provide the
RADIUS authentication data when required.
• All data transmission is encrypted using the WPA2 standard. Keys
are automatically generated, so no key input is required.
•RADIUS - RADIUS mode utilizes RADIUS server for authentication and
dynamic WEP key generation for data encryption.

network capacity, data throughput rate, range and coverage. Performance
depends upon many factors, conditions and variables, including products used,
interference and other adverse conditions. 802.11ac 1300 Mbps in the 5GHz Band
is approximately 3 x faster than 802.11n 450 Mbps in the 2.4GHz Band. An 802.11ac

WMM (Wi-Fi Multimedia) is a component of the IEEE 802.11e
wireless LAN standard for QoS.
WMM provides prioritization of wireless data packets from
different applications based on four access categories: voice,
video, best effort, 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

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 await-ing 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.
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.
•Thewirelessaccesspointisproperlyinstalled,LANconnectionsareOK,
and it is powered ON. Check the LEDs for system and port status.
•EnsurethatyourPCandthewirelessaccesspointareonthesamenetwork
segment. (If you don’t have a router, this must be the case.)
•YoucanusethefollowingmethodtodeterminetheIPaddressofthe
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. 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.
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 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:

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.
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.
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.
•Accesspointsuseafixedchannel.Youcanselectthechannelused.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:
•5.180to5.240GHz;4channels
•5.745to5.825GHz;5channels
39
Appendix B About Wireless LANs
Linksys
•Whenusingmultipleaccesspointsitisbetterifadjacentaccesspoints
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.
•InInfrastructureModewirelessstationsnormallyscanallchannelslooking
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.)
•IfusingAd-hocMode(noaccesspoint)allwirelessstationsshouldbeset
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-bitencryption 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 authentica-tion according to the 802.1X standard. Data transmissions are
encrypted using the WPA standard.
If this option is used:
•TheaccesspointmusthaveaclientloginontheRADIUSserver.
•EachusermusthaveauserloginontheRADIUSserver.
•Eachuser’swirelessclientmustsupport802.1Xandprovidethelogindata
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:
•TheaccesspointmusthaveaclientloginontheRADIUSserver.
•EachusermusthaveauserloginontheRADIUSserver.
•Eachuser’swirelessclientmustsupport802.1Xandprovidethelogindata
when required.
All data transmission is encrypted using the WPA2 standard. Keys are automatically
generated, so no key input is required.
8 02 .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:
•TheaccesspointmusthaveaclientloginontheRADIUSserver.
•EachusermusthaveauserloginontheRADIUSserver.
•Eachuser’swirelessclientmustsupport802.1Xandprovidethelogindata

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.
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.
41
Appendix C PC And Server Configuration
Linksys
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.
•Itmustprovideandacceptcertificatesforuserauthentication.
•Theremustbeaclientloginforthewirelessaccesspointitself.
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.
•Encryptionsettingsmustbecorrect.
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

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.
