The following table describes the labels in this screen.
6.5  MAC Filter
The MAC filter screen allows you to configure the NBG-418N to give exclusive access to up to 16 
devices (Allow) or exclude up to 16 devices from accessing the NBG-418N (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-418N’s MAC filter settings, click Network > Wireless LAN > MAC Filter. The 
screen appears as shown.

LABEL
DESCRIPTION
Security Mode
Choose WPA-PSK or WPA2-PSK from the drop-down list box.
WPA Compatible
This option is available only when you select WPA2-PSK in the Security Mode field.
Select this option to have both WPA2 and WPA wireless clients be able to communicate 
with the NBG-418N even when the NBG-418N is using WPA2-PSK.
Cipher Type 
Select the encryption type (TKIPAES or TKIP+AES) for data encryption.
Select AES if your wireless clients can all use AES. Otherwise, select TKIP or select 
TKIP+AES to allow the wireless clients to use either TKIP or AES.
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.
