The following table describes the labels in this screen.

Table 30   Wireless: WPA-PSK/WPA2-PSK

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 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-PSK/

WPA2-PSK key management) or RADIUS server (if using WPA/WPA2 key 

management) sends a new group key out to all clients. The re-keying process is 

the WPA/WPA2 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 ZyXEL Device 

default is 1800 seconds (30 minutes).
