LABEL
Pre-Shared Key The encryption mechanisms used for WPA and WPA-PSK are the same. The only
difference between the two is that WPA-PSK uses a simple common password,
instead of user-specific credentials.
Type a pre-shared key from 8 to 63 case-sensitive ASCII characters (including spaces
and symbols).
ReAuthentication Specify how often wireless stations have to reenter usernames and passwords in order
Timer (in to stay connected. Enter a time interval between 10 and 9999 seconds. The default
seconds) time interval is 1800 seconds (30 minutes).
Idle Timeout The ZyAIR 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 The WPA Group Key Update Timer is the rate at which the AP (if using WPA-PSK
Update Timer 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 ZyAIR default is 1800 seconds (30 minutes).

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 supplicants are the WPA patch for
Windows XP, Funk Software's Odyssey client, and Meetinghouse Data Communications' AEGIS client.
The Windows XP patch is a free download that adds WPA capability to Windows XP's built-in "Zero
Configuration" wireless client. However, you must run Windows XP to use it.
