DESCRIPTION

 

 

Idle Timeout (In

The ZyXEL Device automatically disconnects a wireless station from the wireless

 

 

Seconds)

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

The Group Key Update Timer is the rate at which the AP (if using WPA-PSK/

 

 

Update Timer (In

WPA2-PSKkey management) or RADIUS server (if using WPA(2) key

 

 

Seconds)

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-PSKmode. The default is 1800 seconds

 

 

 

(30 minutes).
