WEP Encryption
WEP encryption scrambles the data transmitted between the wireless stations and the access points
to keep network communications private. It encrypts unicast and multicast communications in a
network. Both the wireless stations and the access points must use the same WEP key.
Your NBG-418N v2 allows you to configure up to four 64-bit or 128-bit WEP keys but only one key
can be enabled at any one time.
In order to configure and enable WEP encryption; click
Network
>
Wireless LAN
to display the
General
screen. Select
WEP
from the
Security Mode
list.

("0-9", "A-F").
If you chose
128-bit WEP

MAC Filter
The MAC filter screen allows you to configure the NBG-418N v2 to give exclusive access to up to 16
devices (Allow) or exclude up to 16 devices from accessing the NBG-418N v2 (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.

with other APs.
Enable Intra-BSS
Traffic
A Basic Service Set (BSS) exists when all communications between wireless clients or
between a wireless client and a wired network client go through one access point (AP).
Intra-BSS traffic is traffic between wireless clients in the BSS. When Intra-BSS is
enabled, wireless client
A
and
B
can access the wired network and communicate with
each other. When Intra-BSS is disabled, wireless client
A
and
B
can still access the wired
network but cannot communicate with each other.
