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.
ReAuthentication
Timer This field is available only when you select WPA2.
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
Update Timer This field is available only when you select WPA.
The Group Key Update Timer is the rate at which the AP (if using
WPA(2)-PSK key 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)-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.
