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 wireless
network after a period of inactivity. The wireless station needs to send the
username and password again before it can use the wireless network again. Some
wireless clients may prompt users for a username and password; other clients may
use saved login credentials. In either case, there is usually a short delay while the
wireless client logs in to the wireless network again.
This value is usually smaller when the wireless network is keeping track of how
much time each wireless station is connected to the wireless network (for example,
using an authentication server). If the wireless network is not keeping track of this
information, you can usually set this value higher to reduce the number of delays
caused by logging in again.
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.
