Introduction
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.

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.
• 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 selected:
19
Wireless Access Point User Guide
• 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 auto matically
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.
• Each user's wireless client must support 802.1x and provide the login data when re-
quired.
• All data transmission is encrypted using the WEP standard. You only have to select
the WEP key size; the WEP key is automatically generated.

Security Settings - None
Figure 13: Wireless Security - None
Setup
No security is used. Anyone using the correct SSID can connect to your network.
The only settings available from this screen are Radius MAC Authentication and UAM
(Universal Access Method).
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 th e
Radius Server for authentication.

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 provide relevan t an d 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-

tion list table.

UAM authentication - External
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. 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.

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 Wireless
Access Point.
6. When an associated client tries to use HTTP (TCP, port 80) connections, they 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 “
thentication
” in the log table, and station status would show as “Authenticated”

• If a client fails authentication, “

xx:xx:xx:xx:xx:xx WEB authentication
station list table.
UAM Screen
The UAM screen will look different depending on the current security setting. If you have
already provided the address of your Radius server, you won't be prompted for it again.

If selected, then when a user first tries to access the Internet, they will
be blocked, and re-directed to the built-in login page. The logon data is
then sent to the Radius Server for authentication.

If selected, then when a user first tries to access the Internet, they will
be blocked, and re-directed to the URL below. This needs to be on
your own local Web Server. The page must also link back to the builtin login page on this device to complete the login procedure.
Login URL
Enter the URL of the page on your local Web Server you wish users to
see when they attempt to access the Internet, but are not logged in.
Login Failure
URL
Enter the URL of the page on your local Web Server you wish users to
see if their login fails. (This may be the same URL as the Login URL).
Security Settings - WEP
This is the 802.11b standard. Data is encrypted before transmission, but the encryption system
is not very strong.

Select the desired option, and ensure your Wireless stations have the
same setting:
• 64 Bit Encryption - Keys are 10 Hex (5 ASCII) characters.
• 128 Bit Encryption - Keys are 26 Hex (13 ASCII) characters.
• 152 Bit Encryption - Keys are 32 Hex (16 ASCII) characters.
Normally, you can leave this at “Automatic”, so that Wireless Stations
can use either method ("Open System" or "Shared Key".).
If you wish to use a particular method, select the appropriate value "Open System" or "Shared Key". All Wireless stations must then be set
to use the same method.
Select "Hex" or "ASCII" depending on your input method. (All keys
are converted to Hex, ASCII input is only for convenience.)
Enter the key values you wish to use. The default key, selected by the
radio button, is required. The other keys are optional. Other stations
must have matching key values.
Use this to generate a key or keys, instead of entering them directly.
Enter a word or group of printable characters in the Passphrase box
and click the "Generate Key" button to automatically configure the
WEP Key(s).
The current status is displayed.
Click the "Configure" button to configure this feature if required.

Security 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.
