Dual-Band Wireless Access Point

Instant Wireless

Series

Chapter 3: Getting to Know the

Dual-Band Wireless Access Point

The Access Point’s ports, where a network cable is connected, are located on

the Access Point’s back panel.

LAN

This

LAN

(Local Area Network) port connects to

Ethernet network devices, such as a hub, switch, or

router.

Power

The

Power

port is where you will connect the power

adapter.

Power Switch

The

Power Switch

is where you will turn the Access

Point on and off.

Reset Button

There are two ways to Reset the Access Point’s factory

defaults. Either press the Reset Button, for approximate-

ly ten seconds, or restore the defaults from the password

tab in the Access Point’s Web-Based Utility.

Power

Green

. The

Power

LED lights up when the Access Point is

powered on.

Diag

Red

. The

Diag

LED indicates the Access Point’s self-diagnosis

mode during boot-up and restart. It will turn off upon com-

pleting the diagnosis. If this LED stays on for an abnormally

long period of time, refer to the Troubleshooting Appendix.

WLAN Act

Green

. If the WLAN’s

Act

LED is flickering, the Access Point

is actively sending or receiving data to or from one of the

devices on the network.

WLAN Link

Green

. The WLAN’s

Link

LED lights whenever there is a suc-

cessful wireless connection.

LAN Act/Link

Green

. The LAN’s

LINK

LED serves two purposes. If the

LED is continuously lit, the Access Point is successfully con-

nected to a device through the LAN port. If the LED is flick-

ering, it is an indication of any network activity.

LAN Full/Col

Green

. The LAN’s

Full/Col

LED also serves two purposes.

When this LED is continuously lit, the connection made

through the corresponding port is running in Full Duplex

mode. A flickering LED indicates that the connection is expe-

riencing collisions. Infrequent collisions are normal. If this

LED blinks too often, there may be a problem with your con-

nection. Refer to the Troubleshooting Appendix if you think

there is a problem.

LAN 100

Orange

. The LAN’s

100

LED indicates when a successful

100Mbps connection is made through the LAN port.

Important:

Resetting the Access Point will erase all of your settings

(WEP Encryption, Wireless and LAN settings, etc.) and replace

them with the factory defaults. Do not reset the Access Point if you

want to retain these settings

Chapter 5: Setting Up the Dual-

Band Wireless Access Point

Now that you’ve connected the Access Point to your wired network, you are

ready to begin setting it up. This Setup Wizard will take you through all the

steps necessary to configure the Access Point.

Insert the Setup Wizard CD into your PC’s CD-ROM drive. Your PC must

be on your wired network to set up the Access Point.

The screen in Figure 5-1 should appear on your monitor. If it does not, this

means the autorun is not functioning. Start the Setup Wizard manually by

clicking the

Start

button, selecting

Run

, and typing

d:\setup.exe

(where

“D” is your PC’s CD-ROM drive). Click the

Setup

button to continue this

Setup Wizard. Clicking the

User Guide

button opened this User Guide. To

access the Linksys web site on an active Internet connection, click the

Linksys Web

button or to exit this Setup Wizard, click the

Exit

button.

Chapter 4: Connecting the Dual-

Band Wireless Access Point

Locate an optimum location for the

Access Point.

The best place for the

Access Point is usually at the center of your wireless network, with line of

sight to all of your mobile stations.

Fix the direction of the antenna.

Try to place it in a position which can

best cover your wireless network. Normally, the higher you place the anten-

na, the better the performance will be. The antenna’s position enhances the

receiving sensitivity.

Connect a standard Ethernet network cable to the Access Point.

Then,

connect the other end of the Ethernet cable to a switch or hub. The Access

Point will then be connected to your 10/100 Network.

Connect the AC Power Adapter to the Access Point’s Power Socket.

Only use the power adapter supplied with the Access Point. Use of a differ-

ent adapter may result in product damage.

Now that the hardware installation is complete, proceed to

Chapter 5: Setting

Up the Dual-Band Wireless Access Point

for directions on how to set up the

Access Point.

Dual-Band Wireless Access Point

Instant Wireless

Series

Have You:

Connected the Access Point to a hub, switch or router

on your wired network as shown in Chapter 4: Connecting the

Dual-Band Wireless Access Point?

The Access Point can only be

set up through your wired network.

Note:

While the Access Point has been designed to work correctly

right out of the box, setting it up on a wireless computer will require

you to use the Linksys default settings. These settings can then be

changed with the Setup Wizard or Web-based Browser Utility.

Note:

In order for all other wireless devices to communicate with

the Access Point, those devices must be operating in the

Infrastructure Mode

If any wireless devices are configured in

the

Ad Hoc Mode

, they

will not

be recognized by the Access Point.
