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. 
5.4.8  WPA(2) 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(2) application example with an external RADIUS server 
looks as follows. "A" is the RADIUS server. "DS" is the distribution system.
The AP passes the wireless client's authentication request to the RADIUS server.
The RADIUS server then checks the user's identification against its database and grants 
or denies network access accordingly.
The RADIUS server distributes a Pairwise Master Key (PMK) key to the AP that then 
sets up a key hierarchy and management system, using the pair-wise key to dynamically 
generate unique data encryption keys to encrypt every data packet that is wirelessly 
communicated between the AP and the wireless clients.
