DESCRIPTION
Select WPA from the drop-down list.
Specify how often wireless stations have to resend user names and passwords in
order to stay connected. Enter a time interval between 10 and 65535 seconds.
If wireless station authentication is done using a RADIUS server, the
reauthentication timer on the RADIUS server has priority.
The ZyWALL automatically disconnects a wireless station from the wired network
after a period of inactivity. The wireless station needs to enter the user name and
password again before access to the wired network is allowed.
Click RADIUS to go to the RADIUS screen where you can configure the ZyWALL to
check an external RADIUS server.
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.
Click Apply to save your changes back to the ZyWALL.
Click Reset to begin configuring this screen afresh.
