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

Table 33   Wireless: WPA(2)-PSK

Security Mode

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

WPA Compatible

This field is only available for WPA2-PSK. Select this if you want the ZyXEL 

Device to support WPA-PSK and WPA2-PSK simultaneously.

Pre-Shared Key 

The encryption mechanisms used for WPA(2) and WPA(2)-PSK are the same. 

The only difference between the two is that WPA(2)-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 stations 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 station authentication is done using a RADIUS 

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

Idle Timeout

The ZyXEL Device automatically disconnects a wireless station from the wired 

network after a period of inactivity. The wireless station needs to enter the 

username and password again before access to the wired network is allowed. The 

default time interval is 3600 seconds (or 1 hour).

Group Key 

Update Timer

The Group Key Update Timer is the rate at which the AP (if using WPA(2)-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(2)-PSK mode. The ZyXEL Device default is 1800 seconds (30 minutes).
