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 ZyXEL Device
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.
Key 1 to Key 4
The WEP keys are used to encrypt data. Both the NBG-419N 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.
The default key is key 1.

MAC Filter
The MAC filter screen allows you to configure the NBG-419N to give exclusive access to devices
(Allow) or exclude devices from accessing the NBG-419N (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-419N’s MAC filter settings, click

RTS/CTS
Threshold
Data with its frame size larger than this value will perform the RTS (Request To
Send)/CTS (Clear To Send) handshake.
Enter a value between 256 and 2432.
Fragmentation
Threshold
The threshold (number of bytes) for the fragmentation boundary for directed
messages. It is the maximum data fragment size that can be sent. Enter an even
number between
256
and

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.
Output Power
Set the output power of the NBG-419N in this field. If there is a high density of APs
in an area, decrease the output power of the NBG-419N to reduce interference with
other APs. Select one of the following
100%
,
90%
,
75%
,
50%
,
25%

419N’s output power.
HT (High Throughput) Physical Mode - Use the fields below to configure the 802.11 wireless
environment of your NBG-419N.
Operating
Mode
Choose this according to the wireless mode(s) used in your network.
Mixed Mode
- Select this if the wireless clients in your network use different
wireless modes (for example, IEEE 802.11b/g and IEEE 802.1n modes)
Green Mode
- Select this if the wireless clients in your network uses only one type
of wireless mode (for example, IEEEE 802.11 n only)
Channel
Bandwidth
Select the channel bandwidth you want to use for your wireless network.
It is recommended that you select
20/40
(20/40 MHz).
Select 20 MHz if you want to lessen radio interference with other wireless devices in
your neighborhood.

Guard Interval
Select

to increase data throughput. However, this may make data transfer
more prone to errors.
Select
Long
to prioritize data integrity. This may be because your wireless network
is busy and congested or the NBG-419N is located in an environment prone to radio
interference.
Extension
Channel
This is set to
Auto

If you select
20/40
as your
Channel Bandwidth
, the extension channel enables
the NBG-419N to get higher data throughput. This also lowers radio interference
and traffic.
