Table 27 Wireless: WPA/WPA2

LABEL

DESCRIPTION

WPA Compatible

This check box is available only when you select WPA2-PSKor 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.

 

 

ReAuthentication

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

Timer (in seconds)

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

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

Timer

WPA2-PSKkey 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-PSKmode. The ZyXEL Device

 

 

default is 1800 seconds (30 minutes).
