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.

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

screen appears as shown.

Table 29

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

LABEL

DESCRIPTION

Security Mode

Choose

WPA-PSK

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 (

TKIP

AES

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.
