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 Chapter 3,
“Protecting Your Wireless Network”. Deploy the security features
appropriate to your needs.

Setting Up Basic Wireless Connectivity 9
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.
• 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.
Note: Failure to follow these guidelines can result in significant
performance degradation or inability to wirelessly connect to the
wireless access point.

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 page 3.
Please follow the steps below to successfully install the WAB102 802.11 a+b Dual
Band Wireless Access Point.
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.

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.
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.
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.

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.
