The following table describes the labels in this screen.

Table 27 Wireless: WPA/WPA2

LABEL DESCRIPTION

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.

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).

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.

Accounting Server

Active Select Yes from the drop down list box to enable user accounting through an

external authentication server.

IP Address Enter the IP address of the external accounting server in dotted decimal notation.

Port Number Enter the port number of the external accounting server. The default port number

is 1813.

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 accounting server and the ZyXEL Device.

The key must be the same on the external accounting server and your ZyXEL

Device. The key is not sent over the network.

Apply Click Apply to save your changes back to the ZyXEL Device.

Reset Click Reset to reload the previous configuration for this screen.
