NBG-417N User’s Guide

The MAC filter screen allows you to configure the NBG-417N to give exclusive access to up to 16 
devices (Allow) or exclude up to 16 devices from accessing the NBG-417N (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 address of the devices to configure this screen.

To change your NBG-417N’s MAC filter settings, click Network > Wireless LAN > MAC Filter. The 
screen appears as shown.

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 default is 1800 
seconds (30 minutes).
