Introduction  
The D-Link Air DWL-520 11Mbps Wireless PCI Adapter is an ideal way to  
connect your computer to a wireless network or as part of a wired LAN (Local  
Area Network) with a wireless segment. After completing the steps outlined  
in the Quick Install Guide (included separately) you will have the ability to  
share information and resources, such as files and printers, and take full  
advantage of a “connected” environment for work and play!  
This DWL-520 comes with drivers for the most popular operating systems  
and can be integrated into a larger network, running Windows XP, Windows  
2000, Windows ME, or Windows 98 in either Ad Hoc mode (without an  
Access Point) or Infrastructure mode (with an Access Point.) Yet the IEEE  
802.11b standards compliance means this adapter gives you the flexibility to  
connect it to any 802.11b network. The IEEE 802.11b Ethernet standard  
allows you to connect computers and devices at speeds up to 11Mbps,  
dependent upon the distance between wireless adapters.  
This manual provides a quick introduction to wireless technology and its  
application as it relates to networking. Take a moment to read through this  
manual and familiarize yourself with wireless technology. But you should  
also give yourself some time to become familiar with your new wireless  
network.

Wireless Basics  
D-Link Air wireless products are based on industry standards to provide easy  
to use and compatible high-speed wireless connectivity within your home or  
business. Strictly adhering to IEEE 802.11b, the D-Link Air wireless family of  
products will allow you to access the data you want, when and where you  
want it. No longer will you be tethered to a workstation or forced to run new  
wiring. You will be able to enjoy the freedom that wireless networking  
delivers.  
Standards - Based Technology  
The IEEE 802.11b standard designates that devices operate at an optimal  
data rate of 11 Megabits per second. This means you will be able to transfer  
large files quickly or even watch a movie in MPEG format over your network  
without noticeable delays. This technology works by using multiple  
frequencies in the 2.4GHz range utilizing Direct Sequence Spread Spectrum  
(DSSS) technology. D-Link Air products will automatically sense the best  
possible connection speed to ensure the greatest speed and range possible  
with the technology.  
Installation Considerations  
Designed to go up to 300 feet (100 meters) indoors and up to 900 feet (273  
meters) outdoors, D-Link Air DWL-520 lets you access your network from  
virtually anywhere you want. Keep in mind, however, that the number and  
thickness of walls, ceilings or other objects that the wireless signals must  
pass thru may limit range. Typical ranges vary depending on the types of  
materials and background RF noise in your home or business. The key to  
maximizing range is to follow these basic principles:  
Wireless Basics (continued)  
1. Keep the number of walls and ceilings between the access point and your  
receiving device to a minimum - Each wall or ceiling can reduce your D-  
Link Air Wireless product’s range from 3-90 feet. For some business or  
large residential home deployment, I may be more beneficial to have  
more than one access point with overlapping coverage.  
2. Be aware of the direct line between Access Points, Residential Gateways,  
and Computers - A wall that is 1.5 feet thick, at a 45 degree angle  
appears to be almost 3 feet thick. At a 2 degree angle it looks over 42  
feet thick! Try to make sure that the AP and Adapters are positioned so  
that the signal will travel straight through a wall or ceiling for better  
reception.  
3. Building Materials make a difference - A solid metal door or aluminum  
studs may have a negative effect on range. Again, try to position Access  
Points, Residential Gateways, and Computers so that the signal passes  
through drywall or open doorways and not other materials.  
4. Make sure that the antenna is positioned for best reception by using the  
software signal strength tools included with your product.  
5. Keep your product away (at least 3-6 feet) from electrical devices that  
generate RF noise, like microwaves, monitors, electric motors, etc.  
For the average residence, range should not be a problem. If you  
experience low or no signal strength in areas of your home that you wish  
to access, consider positioning the Access Point in a location directly  
between the Residential Gateways and/or Computers that will be  
connected. Additional Access Points can be connected to provide better  
coverage in rooms where the signal does not appear as strong as desired.

Wireless Basics (continued)  
Using radio frequency (RF) technology, WLANs transmit and receive data  
over the air, minimizing the need for wired connections. Thus, WLANs  
combine data connectivity with user mobility, and, through simplified  
configuration, enable movable LANs.  
· Installation Speed and Simplicity - Installing a wireless LAN system can  
be fast and easy and can eliminate the need to pull cable through walls  
and ceilings.  
· Installation Flexibility - Wireless technology allows the network to go  
where wires cannot go.  
· Reduced Cost-of-Ownership - While the initial investment required for  
wireless LAN hardware might be higher than the cost of wired LAN  
hardware, overall installation expenses and life-cycle costs will be  
significantly lower. Long-term cost benefits are greatest in dynamic  
environments requiring frequent moves, adds, and changes.  
· Scalability - Wireless LAN systems can be configured in a variety of  
topologies to meet the needs of specific applications and installations.  
Configurations are easily changed and range from peer-to-peer networks  
suitable for a small number of users to full infrastructure networks of  
thousands of users that allows roaming over a broad area.  
Configuration Utility  
D-Link Air DWL-520 uses the “Configuration Utility” as the management  
software. The utility provides the user an easy interface to change any  
settings related to the wireless adapter. When the computer is started, the  
“Configuration Utility” starts automatically and the system tray icon is loaded  
in the toolbar. Clicking on the utility icon will start the Configuration Utility.  
Another way to start the Configuration Utility is to click on Start>Programs>D-  
Link DWL-520.  
A new icon -  
will appear in your Icon tray.  
If the icon is in red, it means that DWL-520 NIC configuration is invalid or  
incomplete. A “red” icon may indicate that the adapter is set to an incorrect  
channel or the communication mode is set incorrectly. Verify the settings for  
the DWL-520 and make sure that the computer is within wireless range.  
Double-click on the icon shown above. The screen below will be displayed.

Link Info Tab  
The Link Info Tab displays the current state of your wireless adapter.  
The fields in this menu provide the following information:  
·
·
·
State:shows the association state of your computer with the  
wireless LAN. When operating in Infrastructure mode, this field  
shows the MAC address of the Access Point with which you are  
communicating. When operating in Ad Hoc mode, this field shows  
the virtual MAC address used by computers participating in the Ad  
Hoc network. In both cases, the MAC address will be shown in  
hex format (BSSID.) If the word scanning appears in this field, it  
indicates that networking has not been achieved. The adapter is  
searching for an available Access Point, within range. (Note: If  
there is a problem with driver installation, this field will display an  
error message.)  
Rescan: Pressing the rescan button causes the driver to restart  
and begin its connection procedure. The connection procedure  
differs depending on the mode of the driver.  
·
Infrastructure Mode: The driver will scan all available  
channels continuously until it finds one or more Access  
Points that matches its SS ID. It will then try to authenticate  
and associate with the Access Point.  
·
Ad Hoc Mode: The driver will scan for 5 seconds looking  
for an existing Ad Hoc network using the same SSID. If one  
is not found, the driver will “start” its own Ad Hoc network.  
Current Channel: shows the channel on which the connection is  
made. In Infrastructure mode, this number changes as the radio  
scans the available channels.  
·
·
·
Current Tx Rate:shows the highest transmit rate of the current  
association.  
Throughput: shows the short term transmit and receive  
throughput in bytes/second, and is continuously updated.  
Link Quality: is only active when in Infrastructure Mode. The  
bar graph displays the quality of the link with the Access Point. If  
the Link quality becomes “poor” the driver will begin looking for a  
better Access Point. The graph will be labeled for quality as as  
shown on the following page:  
Link Info Tab continued  
·
·
·
·
·
“Poor”  
“Weak”  
“Fair”  
“Good”  
“Excellent”  
·
Signal Strength: is active only when in Infrastructure Mode.  
The graph displays normalized signal strength averaged over all  
frames over 100 bytes long that are received by the Access Point.  
Configuration Tab  
Select the Configuration tab to access the Configuration menu, as shown  
below. You can make changes to any of the fields shown below, without the  
need to restart your computer.  
10  
Configuration Tab (continued)  
Mode  
The D-Link Air DWL-520 Wireless PCI Adapter can operate in one of two  
modes, which are specified in the Mode field of the Configuration menu.  
Clicking the down arrow at the right of the Mode field displays the available  
modes. The two modes are 802.11 Ad Hoc and Infrastructure.  
·
·
802.11b Ad Hoc – This is the 802.11b peer-to-peer mode of  
operation. In “Ad Hoc” mode, only one wireless “cell” is supported  
for each different SSID. All communication is done from client to  
client without the use of an Access Point. “802.11b Ad Hoc”  
networking uses the same SSID for the wireless adapters in  
establishing the network connection. When “Ad Hoc” mode is  
selected, the utility will provide a selection for setting the channel.  
Infrastructure - This mode of operation requires the presence of an  
802.11b Access Point. All communication is done through the  
Access Point, which relays packets to other wireless clients as well  
as to nodes on a wired Ethernet network.  
Tx  
The transmission rate at which the data packets are transmitted by the client  
of the Access Point. You can set this to the following fixed rates: 1 Mbps;  
2Mbps; 5.5 Mbps or 11 Mbps.  
PS Mode  
Power Saving mode.  
Restore Defaults  
Pressing this button restores each field in the panel to its default value. You  
must also click on “Apply Changes” or “OK” in order for the default settings  
to take effect.  
Undo Changes  
Pressing this button reverts all fields in the panel back to the original values  
that were present when the Configuration Utility was opened from the Task  
bar.  
Apply Changes  
This button becomes active only when one of the fields has been modified.  
Click on this button for changes to take effect. The changes will then be  
saved and will be in effect when the computer is restarted.  
Encryption Tab  
The Encryption menu allows you to enable encryption and to set the  
encryption keys. To see the available encryption methods, click the down  
arrow at the right of the Encryption (WEP) field.  
There are two encryption methods available. The IEEE 802.11 specification  
defines Wired Equivalent Privacy (WEP) using a 64-bit key. This capability  
was extended by the industry to allow a 128-bit key.  
If you specify an encryption method, you will only be able to communicate  
with Access Points and stations that use the same encryption method and  
keys.  
Disabling Encryption  
To disable encryption, click the down arrow at the right of the Encryption field,  
select Disabled, and click the Apply button.  
12  
Encryption Tab (continued)  
Enabling Encryption  
To enable encryption, click the down arrow at the right of the Encryption field,  
select either 64 bit or 128 bit, and click the Apply button. After enabling an  
encryption method, you must then specify encryption keys, as described in  
the following sections.  
Creating Encryption Keys Using a Passphrase  
To create encryption keys using a Passphrase, click the radio button next to  
Create Key with Passphrase and type a character string in the Passphrase  
field. As you type, the Configuration Utility uses an algorithm to generate  
four keys used for encryption.  
When you finish typing your character string and click the Apply button, the  
Configuration Utility uses asterisks to mask both your Passphrase and the  
keys it generates.  
Using a Passphrase to generate the four keys makes it easy to set the same  
keys for all members of your wireless LAN.  
Creating Encryption Keys Manually  
If you wish, you can create encryption keys manually by selecting the  
Encryption tab. Click on the button next to Manual Entry.  
When you click this button, the cursor appears in the field for Key 1. For 64-  
bit encryption, you must type exactly 10 hexadecimal digits in each of the  
four key fields; for 128-bit encryption, you must type exactly 26 hexadecimal  
digits. You then click the Apply button to create your encryption keys. After  
you click the Apply button, the Configuration Utility uses asterisks to mask  
your keys.  
About Tab  
The About tab provides information on the version of the Network Driver,  
the Configuration Utility, and the firmware in the D-Link Air DWL-520  
Wireless PCI Adapter. You will need the firmware version number when  
reporting problems to tech support.

folder. Depends on Password gives other computers access conditional  
upon the password they provide.  
Networking Basics  
Sharing Files (continued)  
O. Passwords: allow you to apply a level of security to your  
shared disk drives and folders. Another computer (user) will be required  
to enter the password you designate here before accessing the disk drive  
or folder. Two passwords are used to give two levels of security (or  
access) to others on the network using the Depends on Password  
setting. Leaving the Password boxes empty gives everyone on the  
network access to the disk drive or folder.  
P. Click OK to continue. You will be prompted to enter the  
password(s) you provided for verification. Retype the  
password(s) just as you entered them the first time.  
Q. You may now access this disk drive or folder from another  
computer on your network. Do so by double-clicking the My Network  
Places icon on your desktop or inside Windows Explorer.  
R. Navigate to the computer with the shared disk drive or  
folder (recognized by the Computer Name you provided), double-click.  
You should now see the disk drive or folder, double-click. If you specified  
a password when sharing this disk drive or folder, you will be prompted  
for the password.  
S. You can access a disk drive or folder shared over the network from most  
Windows applications. To make this process easier, Windows allows  
you to map these disk drives and folders to a drive letter on another  
computer. For example, on a computer where you are accessing a  
shared folder from another computer, inside Windows Explorer right-click  
and select Map Network Drive. You will then be able to assign an  
available drive letter. Checking Reconnect at logon allows Windows to  
map this network drive each time you start your computer.

you can type it into the Network path or queue name:box. However, it is  
easier to click the Browse button and navigate to the location of the printer.  
Click OK when you have selected the desired printer. Finish the  
installation by continuing the Add Printer Wizard normally.  
M. You may now use the Network Printer as if it was connected  
directly. Note: the computer that the printer is connected to must be “on”  
to use the printer. If you find this inconvenient, devices known as  
Network Print Servers are available from D-Link including the DP-301  
and DP-101P+. A Network Print Server would allow you to directly  
connect your printer to your network without worrying about which  
computer is “on.”

to replace the non-conforming Software, the price paid by the original licensee for the non-  
conforming Software will be refunded by D-Link; provided that the non-conforming
