Chapter 7 Wireless LAN

NBG-417N User’s Guide

The following table describes the labels in this screen.

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.

Table 27   Network > Wireless LAN > General: WPA-PSK/WPA2-PSK

WPA 
Compatible

This check box is available only when you select WPA2-PSK in the 
Security Mode field.

Select the check box to have both WPA2 and WPA wireless clients be 
able to communicate with the NBG-417N even when the NBG-417N is 
using WPA2-PSK.

Pre-Shared Key   WPA-PSK/WPA2-PSK uses a simple common password for 

authentication.

Type a pre-shared key from 8 to 63 case-sensitive ASCII characters 
(including spaces and symbols).

Type a pre-shared key less than 64 case-sensitive HEX characters ("0-
9", "A-F").

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).
