MAC Filter
The MAC filter screen allows you to configure the NBG334W to give exclusive access to up
to 32 devices (Allow) or exclude up to 32 devices from accessing the NBG334W (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 NBG334W’s MAC filter settings, click

Select this option if your network environment has multiple APs and you want your
wireless device to be able to access the network as you move between wireless
networks.
Wireless Advanced Setup
RTS/CTS
Threshold
Data with its frame size larger than this value will perform the RTS (Request To
Send)/CTS (Clear To Send) handshake.
If the RTS/CTS value is greater than the
Fragmentation Threshold
value, then the
RTS/CTS handshake will never occur as data frames will be fragmented before they
reach RTS/CTS size.
Enter a value between 0 and 2432.
Fragmentation
Threshold
It is the maximum data fragment size that can be sent. Enter a value between 256
and 2432.
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 NBG334W in this field. If there is a high density of APs
within an area, decrease the output power of the NBG334W to reduce interference
with other APs.
802.11 Mode
Select
802.11b
to allow only IEEE 802.11b compliant WLAN devices to associate
with the NBG334W.
Select
802.11g
to allow only IEEE 802.11g compliant WLAN devices to associate
with the NBG334W.
Select
802.11b/g
to allow either IEEE802.11b or IEEE802.11g compliant WLAN
devices to associate with the NBG334W. The transmission rate of your NBG334W
might be reduced.

Enable WMM QoS
Select this to turn on WMM QoS (Wireless MultiMedia Quality of
Service). The NBG334W assigns priority to packets based on the
802.1q or DSCP information in their headers. If a packet has no
WMM information in its header, it is assigned the default priority.
WMM QoS Policy
Select
Default
to have the NBG334W automatically give a service
a priority level according to the ToS value in the IP header of
packets it sends. WMM QoS (Wifi MultiMedia Quality of Service)
gives high priority to voice and video, which makes them run more
smoothly.
Select
Application Priority
from the drop-down list box to display a
table of application names, services, ports and priorities to which
you want to apply WMM QoS.
The table appears only if you select
Application Priority
in
WMM
QoS Policy
.

This is the number of an individual application entry.
Name
This field displays a description given to an application entry.
Service
This field displays either
FTP
,
WWW

E-mail
or a
User Defined
service to which you want to apply WMM QoS.
Dest Port
This field displays the destination port number to which the
application sends traffic.

Priority
This field displays the priority of the application.
Highest
- Typically used for voice or video that should be high-
quality.
High
- Typically used for voice or video that can be medium-quality.
Mid
- Typically used for applications that do not fit into another
priority. For example, Internet surfing.
Low
- Typically used for non-critical “background” applications,
such as large file transfers and print jobs that should not affect
other applications.

WiFi Protected Setup
WiFi Protected Setup (WPS) is an industry standard specification, defined by the WiFi
Alliance. WPS allows you to quickly set up a wireless network with strong security, without
having to configure security settings manually. Depending on the devices in your network, you
can either press a button (on the device itself, or in its configuration utility) or enter a PIN
(Personal Identification Number) in the devices. Then, they connect and set up a secure
network by themselves. See how to set up a secure wireless network using WPS in the
Section
6.2 on page 93
.

Use this screen to enable/disable WPS, view or generate a new PIN number and check current
WPS status. To open this screen, click

Service
The following is a description of the applications you can prioritize with WMM
QoS. Select a service from the drop-down list box.
•
E-Mail
Electronic mail consists of messages sent through a computer network to
specific groups or individuals. Here are some default ports for e-mail:
POP3 - port 110
IMAP - port 143
SMTP - port 25
HTTP - port 80
•
FTP
File Transfer Protocol enables fast transfer of files, including large files that it
may not be possible to send via e-mail. FTP uses port number 21.
•
WWW
The World Wide Web is an Internet system to distribute graphical, hyper-
linked information, based on Hyper Text Transfer Protocol (HTTP) - a client/
server protocol for the World Wide Web. The Web is not synonymous with the
Internet; rather, it is just one service on the Internet. Other services on the
Internet include Internet Relay Chat and Newsgroups. The Web is accessed
through use of a browser.
•
User-Defined
User-defined services are user specific services configured using known ports
and applications.
Dest Port
This displays the port the selected service uses. Type a port number in the
field provided if you want to use a different port to the default port.
Priority
Select a priority from the drop-down list box.
