 Manual, Warranty and Drivers on CD

 Printed Quick Installation Guide
If any of the above items are missing, please contact your reseller.
System Requirements for Configuration:

 A desktop computer with an available 32-bit PCI slot

 Windows XP/2000/Me/98SE

 At least 32 MB of memory and a 300 MHz processor

 An 802.11g or 802.11b access point (for Infrastructure mode),
or another 802.11g or 802.11b wireless adapter (for Ad-Hoc,
Peer-to-Peer networking mode.)
Introduction
TM
The D-Link AirPlus Xtreme G DWL-G520 Wireless PCI Adapter is an 802.11b/802.11g
high-performance, wireless adapter that supports high-speed wireless networking.
Unlike most network cards, the DWL-G520 provides data transfers at up to 54 Mbps (up
to 108Mbps in Super G mode) when used with other D-Link AirPlus Xtreme G products.
The 802.11g standard is backwards compatible with 802.11b devices.
TM
The DWL-G520 has the newest, strongest and most advanced security features available
today. When used with other 802.11 WPA (Wi-Fi Protected Access) and 802.1x compatible
products in a network with a RADIUS server, the security features include:
WPA: Wi-Fi Protected Access which authorizes and identifies users based on a secret
key that changes automatically at regular intervals. WPA uses TKIP (Temporal
Key Integrity Protocol) to change the temporal key every 10,000 packets (a
packet is a kind of message transmitted over a network.) This ensures much
greater security than the standard WEP security. (By contrast, the previous
WEP encryption implementations required the keys to be changed manually.)
802.1x: Authentication which is a first line of defense against intrusion. In the
authentication process, the Authentication Server* verifies the identity of the
client attempting to connect to the network. Unfamiliar clients would be denied
access.
For home users that will not incorporate a RADIUS server in their network, the security
for the DWL-G520, used in conjunction with other WPA-compatible 802.11 products, will
still be much stronger than ever before. Utilizing the Pre- Shared Key mode of WPA,
the DWL-G520 will obtain a new security key every time it connects to the 802.11
network. You only need to input your encryption information once in the configuration
menu. No longer will you have to manually input a new WEP key frequently to ensure
security. With the DWL-G520, you will automatically receive a new key every time you
connect, vastly increasing the safety of your communication.
*Not all servers can provide Authentication
Features

 Faster Wireless Networking with Super G - Speeds up to 15 times faster (up to
108Mbps) with Super G mode. With the DWL-G520 in your PC, you will have the
flexibility of wireless networking speeds that save you time and money.

 Compatible with 802.11b and 802.11g Devices - Fully compatible with the IEEE
802.11b and 802.11g standards, the DWL-G520 can connect with existing 802.11bor 802.11g- compliant routers, access points and cards. That means you can still
communicate with colleagues and friends while you have the ability to link to even
more wireless networks.

 Better Security with 802.1x and WPA -With the DWL-G520 in your desktop PC
you can securely connect to a wireless network using 802.1x for wireless authentication, as well as WPA (Wi-Fi Protected Access) providing you a much higher level of
security for your data and communication than has previously been available.

 32-bit PCI Performance -The DWL-G520 is a powerful 32-bit PCI Adapter that in-
stalls quickly and easily into desktop PCs, and when used with other D-Link Air Plus
Xtreme GTM products will automatically connect to the network out of the box.

 User-friendly configuration and diagnostic utilities.

Wireless Basics
D-Link wireless products are based on industry standards to provide easy-to-use and
compatible high-speed wireless connectivity within your home, business or public access
wireless networks. D-Link wireless products will allow you access to the data you want,
when and where you want it. You will be able to enjoy the freedom that wireless networking
brings.
A Wireless Local Area Network (WLAN) is a computer network that transmits and receives
data with radio signals instead of wires. WLANs are used increasingly in both home and
office environments, and public areas such as airports, coffee shops and universities.
Innovative ways to utilize WLAN technology are helping people to work and communicate
more efficiently. Increased mobility and the absence of cabling and other fixed
infrastructure have proven to be beneficial for many users.
Wireless users can use the same applications they use on a wired network. Wireless
adapter cards used on laptop and desktop systems support the same protocols as
Ethernet adapter cards.
People use WLAN technology for many different purposes:
Mobility - Productivity increases when people have access to data in any location
within the operating range of the WLAN. Management decisions based on real-time
information can significantly improve worker efficiency.
Low Implementation Costs - WLANs are easy to set up, manage, change and
relocate. Networks that frequently change can benefit from WLANs ease of
implementation. WLANs can operate in locations where installation of wiring may be
impractical.
Installation and Network Expansion - Installing a WLAN system can be fast and
easy and can eliminate the need to pull cable through walls and ceilings. Wireless
technology allows the network to go where wires cannot go - even outside the home or
office.
Inexpensive Solution - Wireless network devices are as competitively priced as
conventional Ethernet network devices.
Scalability - WLANs can be configured in a variety of ways 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 larger Infrastructure
networks to accommodate hundreds or thousands of users, depending on the number
of wireless devices deployed.
Wireless Basics (continued)
The DWL-G520 is compatible with the following wireless products:
TM
D-Link AirPlus Xtreme G DWL-G650
Wireless Cardbus Adapter used with laptop computers

 D-Link AirPlus Xtreme G DI-624
TM
Wireless Router
The DWL-G520 is also interoperable with other 802.11g and 802.11b standardscompliant devices.
Standards-Based Technology
The DWL-G520 Wireless PCI Adapter utilizes the 802.11b and the 802.11g standards.
The IEEE 802.11g standard is an extension of the 802.11b standard. It increases the
data rate up to 54 Mbps within the 2.4GHz band, utilizing OFDM technology.
This means that in most environments, within the specified range of this device, 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 transmitting high-speed
digital data over a radio wave utilizing OFDM (Orthogonal Frequency Division Multiplexing)
technology. OFDM works by splitting the radio signal into multiple smaller sub-signals
that are then transmitted simultaneously at different frequencies to the receiver. OFDM
reduces the amount of crosstalk (interference) in signal transmissions. The D-Link DWLG520 will automatically sense the best possible connection speed to ensure the greatest
speed and range possible.
802.11g offers the most advanced network security features available today, including:
WPA , 802.1x, TKIP, AES and Pre-Shared Key mode.
The DWL-G520 is backwards compatible with 802.11b devices. This means that if you
have an existing 802.11b network, the devices in that network will be compatible with
802.11g devices at speeds up to 11Mbps in the 2.4GHz range.
Wireless Basics (continued)
Installation Considerations
TM
The D-Link AirPlus Xtreme G DWL-G520 lets you access your network, using a wireless
connection, from virtually anywhere within its operating range. 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 DWL-G520 and other network
devices to a minimum - each wall or ceiling can reduce your DWL-G520’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 can impede the wireless signal - a solid metal door or aluminum
studs may have a negative effect on range. Try to position wireless devices and
computers with wireless adapters so that the signal passes through drywall or
open doorways and not other materials.
4 Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices
or appliances that generate RF noise.
Getting Started
There are basically two modes of networking:
Infrastructure – using an access point, or wireless router, such as
the DI-624.
Ad-Hoc – directly connecting to another computer, for Peer-to-Peer
communication, using wireless network adapters on each computer,
such as two or more DWL-G520 Wireless PCI Adapters.
On the following pages we will show you an example of an Infrastructure Network and
an Ad-Hoc Network.
An Infrastructure network contains an access point or a wireless router. The
Infrastructure Network example shown on the following page contains the following
D-Link network devices (your existing network may be comprised of other devices):
A wireless router - D-Link AirPlus XtremeTM G DI-624
A laptop computer with a wireless adapter TM
D-Link AirPlus Xtreme G DWL-G650
A desktop computer with a wireless adapter D-Link AirPlus XtremeTM G DWL-G520
A cable modem - D-Link DCM-201
Getting Started (continued)
Setting up a Wireless Infrastructure Network
For a typical wireless
setup at home (as shown
above), please do the
following:
You will need broadband Internet access (a Cable or DSL-subscriber line into
your home or office).
Consult with your Cable or DSL provider for proper installation of the modem.
Connect the Cable or DSL modem to your broadband router.
(See the Quick Installation Guide included with your router).
Install the D-Link AirPlus XtremeTM G DWL-G520 Wireless PCI Adapter into an
available PCI slot on your desktop computer.
(See the Quick Installation Guide included with the network adapter).
Install a D-Link DWL-G650 Wireless Cardbus Adapter into a laptop computer.
(See the Quick Installation Guide included with the DWL-G650).
If you wish, you may connect a computer that is equipped with an Ethernet network adapter (such as a DFE-530TX+) to the router also.
A RADIUS server is optional. Connect a RADIUS server to your network to use all
the features of WPA. (Without a RADIUS server you can still use the WPA PreShared Key mode.) RADIUS Authentication can also be provided by another service provider over the Internet and remote to your network site.
10
Getting Started (continued)
Setting up a Wireless Ad Hoc Network
Install the D-Link DWL-G520 Wireless PCI Adapter into the desktop
computer. (See the Quick Installation Guide included with the product for
installation instructions.)
Install the D-Link DWL-G650 into a laptop computer.
(See the Quick Installation Guide included with the product.)
Set the wireless configuration for the adapters to Ad-Hoc mode, set the
adapters to the same channel, and assign an IP address to each computer
on the Ad-Hoc network. (See the box below).
IP Address
When assigning IP addresses to the computers on the network, please remember
that the IP address for each computer must be in the same IP address range
as all the computers in the network, and the subnet mask must be exactly the
same for all the computers in the network.
For example: If the first computer is assigned an IP address of 192.168.0.2 with a
subnet mask of 255.255.255.0, then the second computer can be assigned an IP
address of 192.168.0.3 with a subnet mask of 255.255.255.0, etc.
IMPORTANT: If computers or other devices are assigned the same IP address,
one or more of the devices may not be visible on the network.

exactly the same as the SSID on the access point or wireless router.
Move the DWL-G520 and the access point or wireless router into the
same room and then test the wireless connection.
Disable all security settings. (WEP, MAC address control, AES).
Turn off your access point and the computer with the DWL-G520. Turn
on the access point, and then turn on the computer with the DWL-G520.
Refresh the DWL-G520 Utility.
Make sure that the access point/router is not locked down to a different
frequency.
3. The DWL-G520 Power and Link lights are not on.
Check to see if the DWL-G520 Wireless PCI Adapter is firmly inserted
into the PCI slot of your laptop computer.
4. I forgot my Encryption key.
Reset the access point to its factory default settings and restore the DWLG520 Wireless PCI Adapter to the factory default settings.
5. The computer does not recognize the DWL-G520 Wireless PCI
Adapter.
Make sure that the DWL-G520 Wireless PCI Adapter is properly seated in
the computer’s PCI slot.
If Windows does not detect the hardware upon insertion of the adapter,
make sure to completely remove drivers that were previously loaded. To
remove the drivers, do the following:
38
Troubleshooting (continued)
A. Under Tools> select Folder Options…> select View > under
Hidden files and folders > select Show hidden files and
folders.
B. Uncheck Hide extension for known file types > click on
Apply.
C. Search for previously loaded driver files. Remove these files
from the INF and SYSTEM32 (DRIVERS) folders in the Windows
directory. Note: Windows XP and Windows 2000 will rename
.inf files that have not received WHQL certification into oem.inf
files (e.g., oem1.inf.)
6. The computer with the DWL-G520 installed is unable to connect to
the wireless network and/or the Internet.
Check that the LED indicators for the broadband modem are indicating
normal activity. If not, there may be a problem with the broadband
connection.
Check that the LED indicators on the wireless router are functioning properly.
If not, check that the AC power and Ethernet cables are firmly connected.
Check that the IP address, subnet mask, gateway, and DNS settings are
correctly entered for the network.
In Infrastructure mode, make sure the same Service Set Identifier (SSID)
is specified on the settings for the wireless clients and access points. The
SSID factory default setting for most D-Link products is default. (Doubleclick on the WLAN icon in the taskbar. The Link Info screen will display
the SSID setting.)
In Ad-Hoc mode, both wireless clients will need to have the same SSID.
Please note that it might be necessary to set up one client to establish a
BSS (Basic Service Set) and wait briefly before setting up other clients.
This prevents several clients from trying to establish a BSS at the same
time, which can result in multiple singular BSSs being established, rather
than a single BSS with multiple clients associated to it.
39
Troubleshooting (continued)
Check that the Network Connection for the wireless client is configured
properly. Select AP (Infrastructure) when connecting to an access point
and select Ad-Hoc mode when connecting without an access point. Doubleclick on the WLAN icon in the taskbar > click on Configuration to change
the settings for the wireless adapter.
If Security is enabled, make sure that the correct encryption keys are
entered on both the DWL-G520 and the access point. Double-click on the
WLAN icon in the taskbar > click Encryption. Check to see that the key
selected is set to the same key as other devices on the network.
7. How can I troubleshoot distance issues using the DWL-G520?
Move the DWL-G520 and access point or wireless router into the same
room and then test the wireless connection.
Change the channel of the access point.
Move devices within the line of sight.

new or have an identical make, model or part. D-Link may in its sole discretion replace the defective
Hardware (or any part thereof) with any reconditioned product that D-Link reasonably determines is
substantially equivalent (or superior) in all material respects to the defective Hardware. Repaired or
replacement Hardware will be warranted for the remainder of the original Warranty Period from the date
of original retail purchase. If a material defect is incapable of correction, or if D-Link determines in its sole
discretion that it is not practical to repair or replace the defective Hardware, the price paid by the original
purchaser for the defective Hardware will be refunded by D-Link upon return to D-Link of the defective
Hardware. All Hardware (or part thereof) that is replaced by D-Link, or for which the purchase price is
refunded, shall become the property of D-Link upon replacement or refund.

refund at D-Link’s sole discretion. Except as otherwise agreed by D-Link in writing, the replacement
Software is provided only to the original licensee, and is subject to the terms and conditions of the
license granted by D-Link for the Software. Software will be warranted for the remainder of the original
Warranty Period from the date or original retail purchase. If a material non-conformance is incapable of
correction, or if D-Link determines in its sole discretion that it is not practical to replace the nonconforming Software, the price paid by the original licensee for the non-conforming Software will be
refunded by D-Link; provided that the non-conforming Software (and all copies thereof) is first returned
