Section 1 - Product Overview
Introduction
The D-Link Wireless 108G DWA-520 Desktop Adapter is a wireless 108G Desktop adapter featuring the latest technology
to deliver data transfer rates up to 108Mbps* in the 2.4GHz frequency. The DWA-520 also works with 802.11b-compliant
devices and when used with other Wireless 108G products delivers throughput speeds capable of handling heavy
data payloads including real-time MPEG video streaming. Plus, the DWA-520 also includes a conguration utility to
discover available wireless networks and create and save detailed connectivity proles for those networks most often
accessed.
The D-Link Wireless 108G DWA-520 is a powerful 32-bit Desktop adapter that installs quickly and easily into desktop
computers. Like all D-Link wireless adapters, the DWA-520 can be used in ad-hoc mode to connect directly with other
cards for peer-to-peer le sharing or in infrastructure mode to connect with a wireless access point or router for access
to the Internet in your ofce or home network.
The DWA-520 features robust security to help protect the wireless network from intruders, complying with the latest
wireless networking security protocols, including WEP encryption and Wi-Fi Protected Access (WPA) support for
both 802.1x and WPA-PSK. The products are also capable of supporting the government-grade AES encryption and
upcoming 802.11i standards. The DWA-520 also includes a conguration utility to discover available wireless networks
and create and save detailed connectivity proles for those networks most often accessed.
* Maximum wireless signal rate derived from IEEE Standard 802.11b/g specications. Actual data throughput will vary. Network conditions and
environmental factors, including volume of network trafc, building materials and construction, and network overhead, lower actual data throughput
rate. Environmental factors may adversely affect wireless signal range.

Section 1 - Product Overview
• 15 times faster - achieve data transfer speeds up to 108Mbps*; up to 15x faster than conventional 802.11b
networks, when used with other 802.11g devices
• Integrates into existing 802.11b wireless networks - no need to invest in all new devices; the
DWA-520 is interoperable with existing 802.11b devices to provide a wireless data rate of up to
11Mbps*
• Stronger Security than ever before with WPA - Wi-Fi Protected Access authorizes and identies users
based on a secret key that changes automatically at a regular interval, for example:
• TKIP (Temporal Key Integrity Protocol), in conjunction with a RADIUS server, changes the temporal key
every 10,000 packets, ensuring greater security
• Pre Shared Key mode means that the home user, without a RADIUS server, will obtain a new security
key every time he or she connects to the network, vastly improving the safety of communications on the
network.
• Extra Protection - 802.1x Authentication in conjunction with the RADIUS server veries the identity of
would be clients
• User-friendly conguration and diagnostic utilities allow you to easily discover available wireless networks
and create and save detailed connectivity proles
• Utilizes OFDM technology (Orthogonal Frequency Division Multiplexing)

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®Vista users: Click Start > Control Panel > Programs & features.
Windows®XP users: Click Start > Control Panel > Add or Remove Programs.
Windows®2000 users: Click Start > Settings > Control Panel > Add or Remove Programs.

Disable Other Wireless Adapters
Most newer computers may include a built-in wireless adapter. To prevent any conicts with the D-Link wireless adapter,
it is recommended to disable the wireless adapter (as well as any unused Ethernet adapters).
From the desktop, right-click on the My Computer icon and select
Properties.
Click the Hardware tab and then click Device Manager. Scroll down
the list and click the +sign to the left of Network Adapters.
Right-click the adapter you would like to disable and select
Disable.

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.
