Wireless-N Access Point with Dual-Band
Chapter 3:
Advanced Configuration
After setting up the Access Point with the Setup Wizard
(located on the CD-ROM), the Access Point will be ready
for use. However, if you want to change its advanced
settings, use the Access Point’s browser-based utility. This
chapter describes each page of the utility and each page’s
key functions. You can access the utility via a web browser
on a computer networked with the Access Point.
The browser-based utility has these main tabs: Setup,
Wireless, Administration, and Status. Additional tabs will
be available after you click one of the main tabs.
How to Access the Browser-based Utility
In order to access the browser-based utility, you need a
web browser and the IP address of the Access Point.
If the Access Point is connected to a network with a DHCP
server (usually the network router), then the Access Point will
obtain its IP address from the DHCP server.
To determine
the Access Point’s IP address, look for it in
your router’s DHCP client table. (Refer to your router’s
documentation for instructions on accessing the DHCP
client table.)
If you cannot find the Access Point’s IP address, then reset
the Access Point. Press the
Reset
button on the Access
Point for approximately five seconds, using a straightened
paper clip. This will restore the Access Point’s factory
default settings. The Access Point will then request an
IP address from the DHCP server (usually the network
router).
After you have determined the Access Point’s IP address,
launch your web browser, and enter the Access Point’s IP
address in the
Address
field. Press
Enter
.
A password request screen appears. (Non-Windows XP
users will see a similar screen.) Leave the
User name
field
blank. Enter the password you created during the Setup
Wizard. If you did not create a new password, use the
default password
admin
. (You can set a new password
from the
Administration >
Management
screen.) Click
OK
to continue.
Password Screen
NOTE:
If the password request screen does not
appear, wait two minutes and try again.
Setup > Basic Setup
The first screen that appears is the
Basic Setup
screen.
Use this screen to change the browser-based utility’s
language, or to change the Access Point’s wired, Ethernet
network settings.
Setup > Basic Setup (Automatic Configuration - DHCP)
Setup > Basic Setup (Static IP)
Language
Language
This is used to set the language displayed by
the browser-based utility. Select the desired language
from the drop-down menu.
Network Setup
This section determines if the Access Point’s IP address is
obtained automatically from a DHCP server, such as your
network router (Automatic Configuration - DHCP), or set
manually (Static IP).
Access Point IP
If your network has a DHCP server,
such as your network router, assigning IP addresses to
your network devices, then keep the default,
Automatic
Configuration - DHCP
. The Access Point will request an
IP address from the DHCP server (usually the network
router).

Wireless > Basic Wireless Settings
Use the
Basic Wireless Settings
screen to configure the
Access Point’s basic wireless and security settings.
There are two ways to configure the Access Point’s
settings, manual and Wi-Fi Protected Setup™. Wi-Fi
Protected Setup™ is a feature that makes it easy to set
up your wireless network. If you have client devices, such
as wireless adapters, that support Wi-Fi Protected Setup,
then you can use Wi-Fi Protected Setup to configure
wireless security for your wireless network.

Wireless Band
This is used to select the 2.4 GHz or 5.0
GHz band.
Network Mode (5 GHz)
From this drop-down menu, you
can select the wireless standards running on your network.
If you have only Wireless-A devices in your network, select
Wireless-A Only
. If you have only Wireless-N devices
in your network, select
Wireless-N Only
. If you have
Wireless-N and Wireless-A devices in your network, keep
the default setting,
Mixed
.
Network Mode (2.4 GHz)
From this drop-down menu,
you can select the wireless standards running on your
network. If you have Wireless-N, Wireless-G, and Wireless-B
devices in your network, keep the default,
Mixed
. If you
have only Wireless-N devices, select
Wireless-N Only
. If
you have only Wireless-G and Wireless-B devices in your
network, select
Wireless-B/G Only
. If you have only
Wireless-G devices, select
Wireless-G Only
. If you have
only Wireless-B devices, select
Wireless-B Only
.
Network Name (SSID)
The SSID is the network name
shared among all points in a wireless network. The SSID
must be identical for all devices in the wireless network. It
is case-sensitive and must not exceed 32 characters (use
any characters on the keyboard). Make sure this setting is
the same for all points in your wireless network. For added
security, you should change the default SSID (
linksys
) to a
unique name.
Channel Width
For best performance in a Wireless-N
network, select
40MHz only
. For Wireless-A, Wireless-G,
and Wireless-B networking only, or if you are not sure
which option to use, keep the default,
20MHz only
.
NOTE:
If you select
40MHz only
for the Channel
Width setting, then Wireless-N can use two
channels: a primary one (Wide Channel) and
a secondary one (Standard Channel). This will
enhance Wireless-N performance.
Wide Channel
If you selected
40 MHz only
for the
Channel Width setting, then select the appropriate
channel for your wireless network. If you are not sure
which channel to select, then keep the default,
Auto
.
Standard Channel
If you selected
20 MHz only
for
the Channel Width setting, then select the appropriate
channel for your wireless network. If you are not sure
which channel to select, keep the default,
Auto
. If you
selected
40MHz only
for the Channel Width setting,
then the Standard Channel will be a secondary channel
for Wireless-N. If you selected a specific channel for the
Wide Channel setting, then the Standard Channel options
will be available. Select the appropriate channel for your
wireless network.
SSID Broadcast
When wireless clients survey the local
area for wireless networks to associate with, they will detect
the SSID broadcast by the Access Point. To broadcast the
Access Point’s SSID, keep the default setting,
Enabled
. If
