Table 40 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 clients 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 client authentication is done using a RADIUS

 

 

server, the reauthentication timer on the RADIUS server has

 

 

priority.

 

 

 

Idle Timeout (In

 

The ZyXEL Device automatically disconnects a wireless client from the wired

Seconds)

 

network after a period of inactivity. The wireless client 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 (In Seconds)

 

WPA2-PSKkey 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-PSKmode. The default is 1800 seconds

 

 

(30 minutes).

Enter a password (up to 31 alphanumeric characters) as the key to be shared

 

 

between the external authentication server and the ZyXEL Device.
