DESCRIPTION

Security Mode

Choose WPA-PSKor WPA2-PSKfrom 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)-PSKare the same.

 

The only difference between the two is that WPA(2)-PSKuses 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

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

Timer (in

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

seconds)

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

The Group Key Update Timer is the rate at which the AP (if using WPA(2)-PSK

Update Timer

key management) or RADIUS server (if using WPA key management) sends a

 

new group key out to all clients. The re-keying process is the WPA 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 mode. The ZyXEL Device default is 1800 seconds (30 minutes).
