About the Wireless Access Point

Congratulations on your purchase of NETGEAR's WAB102 802.11 a+b Dual Band Wireless Access Point, which gives you the ultimate in office mobility. This high-speed wireless device simultaneously supports both IEEE 802.11a and

802.11b wireless networks and lets you quickly network multiple PCs and notebooks without laying new cables, and gives users the freedom to roam throughout the workplace and stay connected to corporate resources, e-mail, and the Internet.

The WAB102 provides built-in capacity and flexibility for growing networks so it's easy to add new clients or move your entire network to a new location. Equipped with auto-sensing capability, it allows packet transfer at up to 108 Mbps in turbo mode for maximum throughput. This access point will automatically adjust to the most efficient speed for the maximum distance in a noisy environment.

Introduction

Chapter 2

Setting Up Basic Wireless Connectivity

This chapter describes how to set up your WAB102 802.11 a+b Dual Band Wireless Access Point for wireless connectivity on your Local Area Network (LAN). This basic configuration will enable computers with 802.11a or 802.11b compliant wireless adapters to do such things as connect to the Internet, or access printers and files on your LAN.

This chapter is divided into three sections:

• For important pre-installation considerations, see “What You Will Need

Before You Begin“ on page 9.

• To install your WAB102, see “Installation Overview“ on page 10.

• For a summary of WAB102 configuration, see “Basic Configuration“ on page

14.

Note: Indoors, computers can connect over 802.11 wireless

networks at a maximum range of up to 500 feet for 802.11b devices and up to 300 feet for 802.11a devices. This distance can

allow for others outside your area to access your network. It is important to take appropriate steps to secure your network from unauthorized access. The WAB102 dual band AP provides highly effective security features which are covered in detail in

“Protecting Your Wireless Network”. Deploy the security features

appropriate to your needs.

User’s Guide for the WAB102 802.11a+b Dual Band Wireless Access Point

What You Will Need Before You Begin

You need to prepare these three things before you can establish a connection through your wireless access point:

• A location for the WAB102 that conforms to the placement and range guidelines below.

• The wireless access point connected to your LAN through a device such as a hub, switch, router, or Cable/DSL gateway.

• One or more computers with properly configured 802.11a or b - compliant wireless adapters.

Placement and Range Guidelines

Indoors, computers can connect over 802.11 wireless networks at a maximum range of 500 feet for 802.11b devices and up to 300 feet for 802.11a devices. However, the operating distance or range of your wireless connection can vary significantly based on the physical placement of the wireless wireless access point.

For best results, identify a location for your wireless access point according to these guidelines:

• Away from potential sources of interference, such as PCs, large metal surfaces, microwaves, and cordless phones. The 802.11a standard operates at a higher frequency and should be less susceptible to interference with cordless phones. This higher 802.11a frequency may not offer as much range of coverage as the lower frequency

802.11b in a indoor environment with lots of obstructions.

Note: Failure to follow these guidelines can result in significant

performance degradation or inability to wirelessly connect to the wireless access point.

• In an elevated location such as a high shelf, near the center of the area in which your PCs will operate. The best location is elevated, such as wall mounted or on the top of a cubicle, and at the center of your wireless coverage area for all the mobile devices.

Setting Up Basic Wireless Connectivity

User’s Guide for the WAB102 802.11a+b Dual Band Wireless Access Point

Cabling Requirements

The WAB102 dual band AP connects to your LAN via twisted-pair Category 5 Ethernet cable with RJ-45 connectors.

Note: The power adapter and cord shipped with the WAB102 limits the

distance from an AC outlet. To overcome this, consider using NETGEAR’s POE101 Power Over Ethernet Adapter with a Category 5 Ethernet cable like the one included with your WAB102. This adapter sends DC power through an Ethernet cable to enable you to power an access point in a remote location.

Installation Overview

Please follow these instructions to successfully install your WAB102.

1. Install the WAB102 Access Point. See below.

2. Configure the Access Point. Turn to page 14.

Note: See “System Requirements“ on page 3 for the minimal system

requirements for installing the WAB102.

Install the WAB102 Wireless Access Point

Before installing the WAB102 802.11 a+b Dual Band Wireless Access Point, you should make sure that your Ethernet network is up and working. You'll be connecting the access point to the Ethernet network so that computers with either

802.11a or 802.11b wireless adapters will be able to communicate with computers

on the Ethernet network. In order for this to work correctly, please verify that you have met all of the system requirements, shown on

Please follow the steps below to successfully install the WAB102 802.11 a+b Dual Band Wireless Access Point.

User’s Guide for the WAB102 802.11a+b Dual Band Wireless Access Point

Note: We suggest you first install the WAB102 with the default

settings. Optionally, you can then customize your settings and enable encryption if it is required.

1. Position and mount the WAB102 Dual Band Wireless Access Point.

The best location is elevated, such as wall mounted or on the top of a cubicle, at the center of your wireless coverage area, and within line of sight of all the mobile devices.

Note: If you are planning to mount your WAB102 on a wall or in a remote

location, we suggest you configure and verify your WAB102's operations first.

2. Connect the Ethernet cable.

Use the Category 5 Ethernet cable included with the product to connect the Ethernet port on the rear panel of WAB102 to a 10 Base-T or 100 Base-Tx network hub, switch, or router.

3. Connect the power cable.

Connect the power cord of the WAB102 power adapter to the 5V DC power socket on the rear panel of the access point. Then, plug the power adapter into an A/C power outlet.

Warning: Use only the power adapter that came with the WAB102.

4. Configure the wireless adapter settings.

To access the WAB102, you need to configure your 802.11a or 802.11b wireless adapter to use the WAB102 factory default settings as follows:

SSID: Wireless

Network Mode: Infrastructure

WEP: Disabled or Off

For a full listing of factory defaults, refer to “Default Factory Settings“ on

page 13.

Setting Up Basic Wireless Connectivity

User’s Guide for the WAB102 802.11a+b Dual Band Wireless Access Point

5. Verify the installation was successful.

The Power light should be lit. It might take a few seconds after the power is applied to the access point for the power light to appear. The Ethernet Link light should be on. If the connection is a 100 Mbps connection, the light is green. If it is a 10 Mbps connection, the light is amber. The Ethernet connection light also flashes to indicate data is moving over the Ethernet connection to the switch, router, or hub. The 802.11a or 802.11b Wireless Link light should be on and blinking. A slow blink indicates that the access point is looking for wireless nodes, or that very little wireless activity is taking place. A fast blink indicates that the access point is receiving or transmitting wireless data.

6. Verify wireless connectivity to your network.

Using a computer with an 802.11a or 802.11b wireless adapter, browse internet or check file access on your network. If everything is functioning properly, then you have successfully installed the WAB102 Dual Band Wireless Access Point.

Having problems? Refer to Chapter 4, “Troubleshooting”.

Note: Once the system is working, consider increased security. See

Chapter 3, “Protecting Your Wireless Network”.
