The following table describes the wireless LAN security labels in this screen.

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.

Table 35   Wireless: WPA-PSK/WPA2-PSK

Security Mode

Choose WPA-PSK or WPA2-PSK from the drop-down list box.

WPA Compatible

This check box is available only when you select WPA2-PSK or WPA2 in the 

Security Mode field.
Select the check box to have both WPA2 and WPA wireless clients be able to 

communicate with the ZyXEL Device even when the ZyXEL Device is using 

WPA2-PSK or WPA2.

Pre-Shared Key 

The encryption mechanisms used for WPA/WPA2 and WPA-PSK/WPA2-PSK are 

the same. The only difference between the two is that WPA-PSK/WPA2-PSK uses 

a simple common password, instead of user-specific credentials.
Type a pre-shared key from 8 to 63 case-sensitive ASCII characters (including 

spaces and symbols).

ReAuthentication 

Timer (In 

Seconds)

Specify how often wireless clients have to resend usernames and passwords in 

order to stay connected. Enter a time interval between 10 and 9999 seconds. The 

default time interval is 1800 seconds (30 minutes). 

Note: If wireless client authentication is done using a RADIUS 

server, the reauthentication timer on the RADIUS server has 
priority.

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).
