Introduction
1
This Chapter provides an overview of the Wireless Access Point's features
and capabilities.
Congratulations on the purchase of your new Wireless Access Point. The Wireless Access
Point links your 802.11g or 802.11b Wireless Stations to your wired LAN. The Wireless
stations and devices on the wired LAN are then on the same network, and can communicate
with each other without regard for whether they are connected to the network via a Wireless or
wired connection.
Figure 1: Wireless Access Point
The auto-sensing capability of the Wireless Access Point allows packet transmission up to
54Mbps for maximum throughput, or automatic speed reduction to lower speeds when the
environment does not permit maximum throughput.
Features of your Wireless Access Point
The Wireless Access Point incorporates many advanced features, carefully designed to provide
sophisticated functions while being easy to use.
Standards Compliant. The Wireless Router complies with the IEEE802.11g (DSSS)
•
specifications for Wireless LANs.
Supports both 802.11b and 802.11g Wireless Stations. The 802.11g standard
•
provides for backward compatibility with the 802.11b standard, so both 802.11b and
802.11g Wireless stations can be used simultaneously.
108Mbps Wireless Connections. 108Mbps connections are available to compatible
•
clients.
1
Wireless Access Point User Guide
•
Bridge Mode Support. The Wireless Access Point can operate in Bridge Mode, con-
necting to another Access Point. Both PTP (Point to Point) and PTMP (Point to MultiPoint) Bridge modes are supported.
And you can even use both Bridge Mode and Access Point Mode simultaneously!
Client/Repeater Access Point. The Wireless Access Point can operate as a Client or
•
Repeater Access Point, sending all traffic received to another Access Point.
Simple Configuration. If the default settings are unsuitable, they can be changed
•
quickly and easily.
DHCP Client Support. Dynamic Host Configuration Protocol provides a dynamic IP
•
address to PCs and other devices upon request. The Wireless Access Point can act as a
DHCP Client, and obtain an IP address and related information from your existing DHPC
Server.
Upgradeable Firmware. Firmware is stored in a flash memory and can be upgraded
•
easily, using only your Web Browser.
PoE Support. You can use PoE (Power over Ethernet) to provide power to the Wireless
•
Access Point, so only a single cable connection is required.
Security Features
• Security Profiles. For maximum flexibility, wireless security settings are stored in
Security Profiles. Up to 8 Security profiles can be defined, and up to 4 used as any time.
Multiple SSIDs. Because each Security Profile has it own SSID, and up to 4 Security
•
Profiles can be active simultaneously, multiple SSIDs are supported. Different clients can
connect to the Wireless Access Point using different SSIDs, with different security settings.
Multiple SSID Isolation. If desired, PCs and devices connecting using different SSIDs
•
can be isolated from each other.
VLAN Support. The 802.1Q VLAN standard is supported, allowing traffic from differ-
•
ent sources to be segmented. Combined with the multiple SSID feature, this provides a
powerful tool to control access to your LAN.
WEP support. Support for WEP (Wired Equivalent Privacy) is included. Both 64 Bit
•
and 128 Bit keys are supported.
WPA support. Support for WPA is included. WPA is more secure than WEP, and
•
should be used if possible. Both TKIP and AES encryption methods are supported.
802.1x Support. Support for 802.1x mode is included, providing for the industrial-
•
strength wireless security of 802.1x authentication and authorization.
Radius Client Support. The Wireless Access Point can login to your existing Radius
•
Server (as a Radius client).
Radius MAC Authentication. You can centralize the checking of Wireless Station
•
MAC addresses by using a Radius Server.
Rogue AP Detection. The Wireless Access Point can detect unauthorized (Rouge)
•
Access Points on your LAN.
Access Control. The Access Control feature can check the MAC address of Wireless
•
clients to ensure that only trusted Wireless Stations can use the Wireless Access Point to
gain access to your LAN.
Password - protected Configuration. Optional password protection is provided to
•
prevent unauthorized users from modifying the configuration data and settings.
2
Introduction
Advanced Features
• Auto Configuration. The Wireless Access Point can perform self-configuration by
copying the configuration data from another Access Point. This feature is enabled by default.
Auto Update. The Wireless Access Point can automatically update its firmware, by
•
downloading and installing new firmware from your FTP server.
Command Line Interface. If desired, the command line interface (CLI) can be used for
•
configuration. This provides the possibility of creating scripts to perform common configuration changes.
NetBIOS & WINS Support. Support for both NetBIOS broadcast and WINS (Win-
•
dows Internet Naming Service) allows the Wireless Access Point to easily fit into your
existing Windows network.
Radius Accounting Support. If you have a Radius Server, you can use it to provide
•
accounting data on Wireless clients.
Syslog Support. If you have a Syslog Server, the Wireless Access Point can send its log
•
data to your Syslog Server.
SNMP Support. SNMP (Simple Network Management Protocol) is supported, allowing
•
you to use a SNMP program to manage the Wireless Access Point.
• UAM Support. The Wireless Access Point supports UAM (Universal Access Method),
making it suitable for use in Internet cafes and other sites where user access time must be
accounted for.
• WDS Support. Support for WDS (Wireless Distribution System) allows the Wireless
Access Point to act as a Wireless Bridge. Both Point-to-Point and Multi-Po int Bridge
modes are supported.

Select the primary profile for 802.11b and 802.11g (2.4 GHz band)
Bridge Mode. This setting determines the SSID and security
settings used for the Bridge connection to the remote AP.
If this option is selected, wireless clients using different profiles
(different SSIDs) are not isolated from each other, so they will be
able to communicate with each other.
If this option is selected, wireless clients using different profiles
(different SSIDs) are isolated from each other, so they will NOT be
able to communicate with each other. They will still be able to
communicate with other clients using the same profile, unless the
"Wireless Separation" setting on the "Advanced" screen has been
enabled.
This option is only useful if the hubs/switches on your LAN support the VLAN (802.1Q) standard.
When VLAN is used, you must select the desired VLAN for each
security profile when configuring the profile. (If VLAN is not
selected, the VLAN setting for each profile is ignored.)
Click the Configure VLAN button to configure the IDs used by each
VLAN. See below for further details.

Traffic generated by this AP will not have a VLAN tag (no VLAN ID).
If selected, each packet generated by this AP will be sent over each
active VLAN, as defined in the client VLAN table above. This requires
that each packet be replicated (up to 8 times). This has a detrimental
effect on performance, so should only be used if necessary.
If selected, you can enter the desired VLAN ID. Normally, this ID
should be one of the client VLAN IDs defined above.

Access Point only has a single band, then only 1 option is available.
Security Settings
Select the desired option, and then enter the settings for the selected method.
The available options are:
• None - No security is used. Anyone using the correct SSID can connect to your network.
• WEP - The 802.11b standard. Data is encrypted before transmission, but the encryption
system is not very strong.
• WPA-PSK - Like WEP, data is encrypted before transmission. WPA is more secure than
WEP, and should be used if possible. The PSK (Pre-shared Key) must be entered on each
Wireless station. The 256Bit encryption key is derived from the PSK, and changes fre-
quently.
• WPA2-PSK - This is a further development of WPA-PSK, and offers even greater secu-
rity, using the AES (Advanced Encryption Standard) method of encryption.
19
Wireless Access Point User Guide
• WPA-PSK and WPA2-PSK - This method, sometimes called "Mixed Mode", allows
clients to use EITHER WPA-PSK (with TKIP) OR WPA2-PSK (with AES).
• WPA with Radius - 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 selected:
• This 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 re-
quired.
• All data transmission is encrypted using the WPA standard . Keys are automatically
generated, so no key input is required.
• WPA2 with Radius - 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 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 stand ard. Keys are automatically
generated, so no key input is required.
• WPA and WPA2 with Radius - EITHER WPA or WPA2 require a Radius Server on
your LAN to provide the client authentication according to the 802.1x standard. Data
transmissions are encrypted using EITHER WPA or 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 EITHER WPA or 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 encryp-
tion. If possible, you should use WPA-802.1x instead, because WPA encryption is much
stronger than WEP encryption.
If this option is selected:
• This Access Point must have a "client login" on the Radius Server.
• Each user must have a "user login" on the Radius Server.

Radius MAC Authentication
Radius MAC Authentication provides for MAC address checking which is centralized on your
Radius server. If you don't have a Radius Server, you cannot use this feature.
Using MAC authentication
1. Ensure the Wireless Access Point can login to your Radius Server.
• Add a RADIUS client on the RADIUS server, using the IP address or name of the
Wireless Access Point, and the same shared key as entered on the Wireless Access
Point.
• Ensure the Wireless Access Point has the correct address, port number, and shared
key for login to your Radius Server. These parameters are entered either on the
Security page, or the Radius-based MAC authentication sub-screen, depending on
the security method used.
• On the Access Point, enable the Radius-based MAC authentication feature on the
screen below.
2. Add Users on the Radius server as required. The username must be the MAC address of
the Wireless client you wish to allow, and the password must be blank.
3. When clients try to associate with the Access Point, their MAC address is passed to the
Radius Server for authentication.
• If successful, “
and client station status would show as “authenticated” on the station list table;
xx:xx:xx:xx:xx:xx MAC authentication” is entered in the log,
21

• If not successful, “
xx:xx:xx:xx:xx:xx MAC authentication failed” is en-
tered in the log,, and station status is shown as “authenticating” on the station list
table.

Access Point Setup
UAM
UAM (Universal Access Method) is intended for use in Internet cafes, Hot Spots, and other
sites where the Access Point is used to provide Internet Access.
If enabled, then HTTP (TCP, port 80) connections are checked. (UAM only works on HTTP
connections; all other traffic is ignored.) If the user has not been authenticated, Internet access
is blocked, and the user is re-directed to another web page. Typically, this web page is on your
Web server, and explains how to pay for and obtain Internet access.
To use UAM, you need a Radius Server for Authentication. The "Radius Server Setup" must
be completed before you can use UAM. The required setup depends on whether you are using
“Internal” or “External” authentication.
• Internal authentication uses the web page built into the Wireless Access Point.
• External authentication uses a web page on your Web server. Generally, you should use
External authentication, as this allows you to provid e relevant and helpful information to
users.
UAM authentication - Internal
1. Ensure the Wireless Access Point can login to your Radius Server.
• Add a RADIUS client on RADIUS server, using the IP address or name of the Wire-
less Access Point, and the same shared key as entered on the Wireless Access Point.
• Ensure the Wireless Access Point has the correct address, port number, and shared
key for login to your Radius Server. These parameters are entered either on the Security page, or the UAM sub-screen, depending on the security method used.
2. Add users on your RADIUS server as required, and allow access by these users.
3. Client PCs must have the correct Wireless settings in order to associate with the Wireles
Access Point.
4. When an associated client tries to use HTTP (TCP, port 80) connections, they will be re-
directed to a user login page.
5. The client (user) must then enter the user name and password, as defined on the Radius
Server. (You must provide some system to let users know the correct name and password
to use.)
6. If the user name and password is correct, Internet access is allowed.
Otherwise, the user remains on the login page.
• Clients which pass the authentication are listed as “
thentication” in the log table, and station status would show as “Authenticated”
on the station list table.
• If a client fails authentication, “
failed” shown in the log, and station status is shown as “Authenticating” on the sta-
xx:xx:xx:xx:xx:xx WEB authentication
tion list table.

• Ensure the Wireless Access Point has the correct address, port number, and shared
key for login to your Radius Server. These parameters are entered either on the Security page, or the UAM sub-screen, depending on the security method used.
2. On your Web Server, create a suitable welcome page.
The welcome page must have a link or button to allow the user to input their user
name and password on the uamlogon.htm page on the Access Point.
23
Wireless Access Point User Guide
3. On the Access Point’s UAM screen, select External Web-based Authentication, and
enter the URL for the welcome page on your Web server.
4. Add users on your RADIUS server as required, and allow access by these users.
5. Client PCs must have the correct Wireless settings in order to associate with the W ireless
Access Point.
6. When an associated client tries to use HTTP (TCP, port 80) connections, th ey will be re-
directed to the welcome page on your Web Server. They must then click the link or button
in order to reach the Access Point’s login page.
7. The client (user) must then enter the user name and password, as defined on the Radius
Server. (You must provide some system to let users know the correct name and password
to use.)
8. If the user name and password is correct, Internet access is allowed.
Otherwise, the user remains on the login page.
• Clients which pass the authentication are listed as “

WEP encryption.
If this option is selected:
• This Access Point must have a "client login" on the Radius Server.
• Each user must have a "user login" on the Radius Server. Normally, a Certificate is used to
authenticate each user. See Chapter4 for details of user configuration.

Chapter 4
PC and Server Configuration

This Chapter details the PC Configuration required for each PC on the local
LAN.
Overview
All Wireless Stations need to have settings which match the Wireless Access Point. These
settings depend on the mode in which the Access Point is being used.
• If using WEP or WPA-PSK, it is only necessary to ensure that each Wireless station's
settings match those of the Wireless Access Point, as described below.
• For WPA-802.1x and 802.1x modes, configuration is much more complex. The Radius
Server must be configured correctly, and setup of each Wireless station is also more com-
plex.
Using WEP
For each of the following items, each Wireless Station must have the same settings as the
Wireless Access Point.
Mode
SSID (ESSID)
Wireless
Security
On each PC, the mode must be set to Infrastructure.
This must match the value used on the Wireless Access Point.
The default value is wireless
Note! The SSID is case sensitive.
• Each Wireless station must be set to use WEP data encryption.
• The Key size (64 bit, 128 bit, 152 bit) must be set to match the
Access Point.
• The keys values on the PC must match the key values on the Access
Point.
Note:
On some systems, the key sizes may be shown as 40bit, 104bit, and
128bit instead of 64 bit, 128 bit and 152bit. This difference arises because the key input by the user is 24 bits less than the key size used for
encryption.

Security
On each PC, the mode must be set to Infrastructure.
This must match the value used on the Wireless Access Point.
The default value is wireless
Note! The SSID is case sensitive.
On each client, Wireless security must be set to WPA-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 a Radius Server - Overview
The Wireless Access Point supports 4 Wireless security methods which use 802.1x for authentication, and thus require Radius Server configuration:
• WPA with Radius
• WPA2 with Radius
• WPA and WPA2 with Radius
• 802.1x (with WEP)
These options differ in the data encryption method, but the 802.1x authentication is the same
for each method. The 802.1x standard for authentication provides greater security and centralized management, but it is more complex to configure.
Radius Server Configuration
If using 802.1x authentication, the Radius Server on your network must be configured as
follow:
• It must provide and accept Certificates for user (wireless client) 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. (How-
ever, your Radius server may 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, matching the settings on the Wireless Access Point
and the wireless clients.
The following section gives details of setting up a Windows 2000 server for 802.1x.
For other Radius Servers, check the documentation provided with the Server.

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 which doesn't require port authentication.
2. Start your Web Browser. In the Address box, enter the IP address of the Windows 2000

Wireless Access Point User Guide
• 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 50: Wireless Networks Screen
2. Select the wireless network from the Available Networks list, and click Configure.
3. Select and enter the correct values, as advised by your Network Administrator.

Using 802.1x Mode (without WPA)
This is very similar to using WPA-802.1x.
The only difference is that on your client, you must NOT enable the setting The key is pro-
vided for me automatically.
Instead, you must enter the WEP key manually, ensuring it matches the WEP key used on the
Access Point.
Figure 52: 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.

Rogue APs
A "Rouge AP" is an Access Point which should not be in use, and so can be considered to be
providing unauthorized access to your LAN.
This Access Point can assist to locate 2 types of Rogue APs:
• APs which have Wireless security disabled.
• APs which are not in the list of valid APs which you have provided.
When a Rogue AP is located, it is recorded in the log. If using SNMP, you can also choose to
have detection of a Rogue AP generate an SNMP trap.

Troubleshooting
B
Overview
This chapter covers some common problems that may be 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 ad vice.
General Problems
Problem 1:
Solution 1:
Can't connect to the Wireless Access Point to configure it.
Check the following:
• The Wireless Access Point is properly installed, LAN connections are
OK, and it is powered ON. Check the LEDs for 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.)
• If your PC is set to "Obtain an IP Address automatically" (DHCP
client), restart it.
• 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.
e.g.
ping RTFF3318
3. Check the output of the ping command to determine the IP address of
the Wireless Access Point, as shown below.
Figure 65: Ping
If your PC uses a Fixed (Static) IP address, ensure that it is using an IP
Address which is compatible with the Wireless Access Point. (If no DHCP
Server is found, the Wireless Access Point will default to an IP Address and
Mask of 192.168.0.228 and 255.255.255.0.) On Windows PCs, you can use
Control Panel-Network to check the Properties for the TCP/IP protocol.
86
Appendix B - Troubleshooting
Problem 2:
Solution 2
My PC can't connect to the LAN via the Wireless Access Point.
Check the following:
• The SSID and WEP settings on the PC match the settings on the Wire-
less 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.

Windows TCP/IP
C
Overview
Normally, no changes need to be made.
• By default, the Wireless Access Point will act as a DHCP client, automatically obtaining a
suitable IP Address (and related information) from your DHCP Server.
• If using Fixed (specified) IP addresses on your LAN (instead of a DHCP Server), there is
no need to change the TCP/IP of each PC. Just configure the Wireless Access Point to
match your existing LAN.
The following sections provide details about checking the TCP/IP settings for various types of
Windows, should that be necessary.
Checking TCP/IP Settings - Windows 9x/ME:
1. Select Control Panel - Network. You should see a screen like the following:

Appendix D
About Wireless LANs
D
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 which 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. However, some Access Points allow connections from Wireless
Stations which have their SSID set to “any” or whose SSID is blank ( null ).
ESS/ESSID
A group of Wireless Stations, and multiple Access Points, all using the same ID (ESSID),
form an Extended Service Set (ESS).
96
Appendix D - About Wireless LANs
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 which has the least interference or best perfo rmance. 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 which provides the least interference and best performance. For 802.11g,
13 channels are available in the USA and Canada., but 11channels are available in North
America if using 802.11b.
• If using multiple Access Points, it is better if adjacent Access Points use different Chan-
nels to reduce interference. The recommended Channel spacing between adjacent Access
Points is 5 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. But if the data is encrypted, then 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
Like WEP, data is encrypted before transmission. WPA is more secure than WEP, and should
be used if possible. The PSK (Pre-shared Key) must be entered on each Wireless station. The
256Bit encryption key is derived from the PSK, and changes frequently.
WPA-802.1x
WPA-802.1x - 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.
