Getting Started
Installation
This section will walk you through the installation process. If you have a built-in wireless adapter, please disable it in
device manager before installing your D-Link adapter. Also, if you have previously installed another wireless adapter,
please make sure any software is uninstalled.
Before installing your new D-Link wireless adapter, please verify the following:
• Remove any previous installations of wireless adapters
• Disable any built-in wireless adapters
• Verify the settings such as the SSID and security settings of the network(s) you want to connect to
Remove Existing Installations
If you’ve installed a different manufacture’s adapter or a different model D-Link adapter, make sure the software is
uninstalled before installing the new software. Some utilities may cause a conict with the new software. If you plan
to use multiple adapters at different times, make sure the utilities are not set to load when your computer boots up.
Windows®XP / Vista users may use the built-in wireless utility for all adapters.
To remove any old software:
Windows® XP / Vista users: Click Start > Control Panel > Add or Remove Programs.
Windows® 2000 users: Click Start > Settings > Control Panel > Add or Remove Programs.

Wireless Installation Considerations
The D-Link wireless adapter lets you access your network using a wireless connection from virtually anywhere within
the operating range of your wireless network. Keep in mind, however, that the number, thickness and location of
walls, ceilings, or other objects that the wireless signals must pass through, may limit the range. Typical ranges vary
depending on the types of materials and background RF (radio frequency) noise in your home or business. The key
to maximizing wireless range is to follow these basic guidelines:
1. Keep the number of walls and ceilings between the D-Link adapter and other network devices to a
minimum - each wall or ceiling can reduce your adapter’s range from 3-90 feet (1-30 meters.) Position
your devices so that the number of walls or ceilings is minimized.
2. Be aware of the direct line between network devices. A wall that is 1.5 feet thick (.5 meters), at a
45-degree angle appears to be almost 3 feet (1 meter) thick. At a 2-degree angle it looks over 42 feet
(14 meters) thick! Position devices so that the signal will travel straight through a wall or ceiling (instead
of at an angle) for better reception.
3. Building Materials make a difference. A solid metal door or aluminum studs may have a negative effect on
range. Try to position access points, wireless routers, and computers so that the signal passes through
drywall or open doorways. Materials and objects such as glass, steel, metal, walls with insulation, water
(sh tanks), mirrors, le cabinets, brick, and concrete will degrade your wireless signal.
4. Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices or appliances that
generate RF noise.
5. If you are using 2.4GHz cordless phones or X-10 (wireless products such as ceiling fans, lights, and
home security systems), your wireless connection may degrade dramatically or drop completely. Make
sure your 2.4GHz phone base is as far away from your wireless devices as possible. The base transmits
a signal even if the phone in not in use.
