NBG410W3G Series User’s Guide

The MAC filter screen allows you to configure the ZyXEL Device to give exclusive access to 
specific devices (Allow) or exclude specific devices from accessing the ZyXEL Device 
(Deny). Every Ethernet device has a unique MAC (Media Access Control) address. The MAC 
address is assigned at the factory and consists of six pairs of hexadecimal characters, for 
example, 00:A0:C5:00:00:02. You need to know the MAC addresses of the devices to 
configure this screen.
To change your ZyXEL Device’s MAC filter settings, click the WIRELESS > Wi-Fi > MAC 
Filter. The screen appears as shown.

To activate MAC filtering on a profile, select Enable from the Enable MAC 
Filtering drop-down list box in the Wireless Card > Edit screen and click 
Apply.

Idle Timeout 

The ZyXEL Device automatically disconnects a wireless client from the wireless 

network after a period of inactivity. The wireless client needs to send the username 

and password again before it can use the wireless network again. Some wireless 

clients may prompt users for a username and password; other clients may use 

saved login credentials. In either case, there is usually a short delay while the 

wireless client logs in to the wireless network again. 
This value is usually smaller when the wireless network is keeping track of how 

much time each wireless client is connected to the wireless network (for example, 

using an authentication server). If the wireless network is not keeping track of this 

information, you can usually set this value higher to reduce the number of delays 

caused by logging in again.
Enter a time interval between 600 and 65535 seconds.

Group Key 

Update Timer 

The Group Key Update Timer is the rate at which the AP sends a new group key 

out to all clients. The re-keying process is the WPA 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.
