Idle Timeout (In 

Seconds)

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. 

Group Key Update 

Timer (In Seconds)

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).

Authentication Server

Shared Secret

Enter a password (up to 31 alphanumeric characters) as the key to be shared 

between the external authentication server and the ZyXEL Device.
The key must be the same on the external authentication server and your ZyXEL 

Device. The key is not sent over the network.

Shared Secret

Enter a password (up to 31 alphanumeric characters) as the key to be shared
