DESCRIPTION
The ZyXEL Device 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.
The Group Key Update Timer is the rate at which the AP (if using WPA-PSK/
WPA2-PSK key management) or RADIUS server (if using WPA(2) key
management) sends a new group key out to all clients. The re-keying process is
the WPA(2) equivalent of automatically changing the WEP key for an AP and all
stations in a WLAN on a periodic basis. Setting of the Group Key Update Timer
is also supported in WPA-PSK/WPA2-PSK mode. The default is 1800 seconds
(30 minutes).
