P-870HW-51a v2 User’s Guide

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.
