DESCRIPTION

 

 

ReAuthentication

This field is available only when you select WPA2.

 

 

Timer

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.

 

 

 

 

 

 

Group Key

This field is available only when you select WPA.

 

 

Update Timer

The Group Key Update Timer is the rate at which the AP (if using

 

 

 

 

 

 

WPA(2)-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(2)-PSKmode. The ZyXEL Device default is 1800 seconds (30

 

 

 

minutes).

 

 

 

 

 

 

Authentication Server

 

 

 

 

 

 

IP Address

Enter the IP address of the external authentication server in dotted

 

 

 

decimal notation.

 

 

 

 

 

 

Port Number

Enter the port number of the external authentication server. The

 

 

 

default port number is 1812.

 

 

 

You need not change this value unless your network administrator

 

 

 

instructs you to do so with additional information.

 

 

 

 

 

 

Shared Secret

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

 

 

 

shared between the external authentication server and the ZyXEL

 

 

 

Device.

 

 

 

The key must be the same on the external authentication server and

 

 

 

your ZyXEL Device. The key is not sent over the network.

 

 

 

 

 

7.5 The WPS Screen

Use this screen to configure WiFi Protected Setup (WPS) on your ZyXEL Device.

WPS allows you to quickly set up a wireless network with strong security, without having to configure security settings manually. Set up each WPS connection between two devices. Both devices must support WPS.
