In order to configure and enable WPA/WPA2; click the Wireless LAN link under Network to 
display the General screen. Select WPA or WPA2 from the Security Mode list.

Figure 88   Wireless: WPA/WPA2

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).
