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 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 2.4G
or
Wireless LAN 5G
to display the
General
screen. Select
Static WEP
from the
Security Mode
list.

to enable data encryption.
PassPhrase
Enter a Passphrase (up to 26 printable characters) and click Generate.
A passphrase functions like a password. In WEP security mode, it is further converted by the
NBG into a complicated string that is referred to as the “key”. This key is requested from all
devices wishing to connect to a wireless network.
WEP Encryption
Select
64-bit WEP
or
128-bit WEP
.
This dictates the length of the security key that the network is going to use.
Authentication
Method
Select
Auto
or
Shared Key
from the drop-down list box.
This field specifies whether the wireless clients have to provide the WEP key to login to the
wireless client. Keep this setting at
Auto
unless you want to force a key verification before
communication between the wireless client and the NBG occurs.
Select
Shared Key
to force the clients to provide the WEP key prior to communication.
ASCII
Select this option in order to enter ASCII characters as WEP key.
Hex
Select this option in order to enter hexadecimal characters as a WEP key.
The preceding "0x", that identifies a hexadecimal key, is entered automatically.

The WEP keys are used to encrypt data. Both the NBG and the wireless stations must use
the same WEP key for data transmission.
If you chose
64-bit WEP
, then enter any 5 ASCII characters or 10 hexadecimal characters
("0-9", "A-F").
If you chose
128-bit WEP
, then enter 13 ASCII characters or 26 hexadecimal characters
("0-9", "A-F").
You must configure at least one key, only one key can be activated at any one time.

MAC Filter
The MAC filter screen allows you to configure the NBG to give exclusive access to devices (Allow) or
exclude devices from accessing the NBG (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’s MAC filter settings, click

Threshold
Data with its frame size larger than this value will perform the RTS (Request To Send)/CTS

Enable Intra-
BSS Traffic
Blocking
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.
Output Power
Set the output power of the NBG in this field. If there is a high density of APs in an area,
decrease the output power of the NBG to reduce interference with other APs. Select one of
the following
100%
,
90%
,
75%
,
