7.4.7 Wireless Client WPA Supplicants
A wireless client supplicant is the software that runs on an operating system instructing the
wireless client how to use WPA. At the time of writing, the most widely available supplicant is
the WPA patch for Windows XP, Funk Software's Odyssey client.
The Funk Software's Odyssey client is bundled free (at the time of writing) with the Prestige
client adaptor(s). This adds WPA capability to Windows XP's built-in "Zero Configuration"
wireless client.
7.4.8 WPA with RADIUS Application Example
You need the IP address of the RADIUS server, its port number (default is 1812), and the
RADIUS shared secret. A WPA application example with an external RADIUS server looks
as follows. “A” is the RADIUS server. “DS” is the distribution system.
1 The AP passes the wireless client’s authentication request to the RADIUS server.
2 The RADIUS server then checks the user's identification against its database and grants
or denies network access accordingly.
Idle Timeout The Prestige automatically disconnects a wireless station from the wired network
after a period of inactivity. The wireless station needs to enter the username and
password again before access to the wired network is allowed. The default time
interval is 3600 seconds (or 1 hour).
WPA Group Key
Update Timer
The WPA Group Key Update Timer is the rate at which the AP (if using WPA-
PSK key management) or RADIUS server (if using WPA key management) sends
a new group key out to all clients. The re-keying process is the WPA equivalent of
automatically changing the WEP key for an AP and all stations in a WLAN on a
periodic basis. Setting of the WPA Group Key Update Timer is also supported in
WPA-PSK mode. The Prestige default is 1800 seconds (30 minutes).
Preamble Select a preamble type from the drop-down list menu. Choices are Long, Short or
Dynamic. The default setting is Long. See the section on preamble for more
information.
802.11 Mode Select 802.11b Only to allow only IEEE 802.11b compliant WLAN devices to
associate with the Prestige.
Select 802.11g Only to allow only IEEE 802.11g compliant WLAN devices to
associate with the Prestige.
Select Mixed to allow either IEEE802.11b or IEEE802.11g compliant WLAN
devices to associate with the Prestige. The transmission rate of your Prestige
might be reduced.
G+ Enhanced Select G+ Enhanced checkbox to allow any ZyXEL WLAN devices that support
this feature to associate with the Prestige. This permits the Prestige to transmit at a
higher speed than the 802.11g Only mode.
