Introduction

The DWA-520 has the newest, strongest, and most advanced security features available
today. When used with other 802.11 WPA/WPA2 (Wi-Fi Protected Access) and 802.1x
compatible products in a network with a RADIUS server, the security features include:

WPA/WPA2: Wi-Fi Protected Access which authorizes and identifies users based on a

secret key that changes automatically at regular intervals. WPA/WPA2 uses
TKIP 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 older WEP encryption req-
uired 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 DWA-520, used in conjunction with other WPA/WPA2-compatible 802.11 prod-

ucts still be much stronger than ever before. Utilizing the Pre Shared Key mode of
WPA/WAP2 the DWA-520 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
configurationmenu. No longer will you have to manually input a new WEP key freque­ntly to ensure security. With the DWA-520, you will automatically receive a new key
every time you connect, vastly increasing the safety of your communication.

* Not all servers can provide Authentication.

The D-Link AirPlus Xtreme G DWA-520 Wireless PCI Adapter is an 802.11g high­performance, wireless adapter that supports high-speed wireless networking at home,
at work or in public places.

Unlike most network cards, the DWA-520 provides data transfers at up to 54 Mbps.
The 802.1 1g standard is backwards compatible with 802.11b products.

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. Y ou 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.

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.

Inexpensive Solution - Wireless network devices are as competitively priced as

conventional Ethernet network devices.

Wireless Basics (continued)

Standards-Based Technology

The DWA-520 Wireless PCI Adapter utilizes the new 802.11g standard.
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.

802.1 1g offers the most advanced network security features available today , including:

WPA/WPA2,802.1x,TKIP,AES and Pre-Shared Key mode. These security feature
are explained in more detail in the Introduction and the Features section of this manual.

The DWA-520 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

802.1 1g devices at speeds up to 1 1Mbp s in the 2.4GHz range.

The DWA-520 is compatible with 802.11g and 802.11b wireless products, which include:

D-Link Air DWL-650,D-Link AirPlus DWL-650+,
D-Link AirPlus Xtreme G DWL-G650

2.4GHz Wireless Cardbus Adapter used with laptop computers

D-Link Air DWL-520, D-Link AirPlus DWL-520+

Installation Considerations

The D-Link AirPlus Xtreme G DWA-520 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 object s that
the wireless signals must pass through, may limit the range. T ypical 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:

Keep your product away (at least 3-6 feet or 1-2 meters) from electrical
devices or appliances that generate RF noise.

4

Keep the number of walls and ceilings between the DWA-520 and other network
devices to a minimum - each wall or ceiling can reduce your DWA-520’s
range from 3-90 feet (1-30 meters.) Position your devices so that the number of
walls or ceilings is minimized.

1

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.

2

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.

Domain Name:

Each server has a domain name that uniquely identifies it. That domain name is normally
contained in the Subject CN field of the server certificate. A server domain name ends
with the name of a larger administrative domain, to which the server belongs.

TTLS Identity:

Tunneled Transport Layer Security satisfies a requirement for strong encryption and
mutual authentication on Wireless networks. EAP-TTLS has a unique feature that other
protocols do not offer . Because it set s up an encrypted tunnel for your credentials, it is
also able to pass your login name through that tunnel. That means that not only are your
credentials secure from eavesdropping, but your identity is protected as well. Thus, with
EAP-TTLS you have two identities: an inner one, and an outer one. The inner identity is
your actual user name. Your outer identity can be completely anonymous. Set your
outer identity in the TTLS Identity field.

Make sure that the SSID on the DWA-520 Wireless PCI Adapter is
exactly the same as the SSID on the Access Point or Wireless Router.

Move the DWA-520 and 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 DWA-520. Turn

on the Access Point, and then turn on the computer with the DWA-520.

Hidden files and folders > select Show hidden files and
folders

B. Uncheck Hide extension for known file types > click on

Apply

C. Search for the files DWLG520.INF and DWLG520.SYS.

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.)

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 the D-LinkAir and AirPlus products is default.
(Double-click 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.

6. The computer with the DWA-520 installed is unable to connect to

the wireless network and/or the Internet.

properly . Select AP (Infrastructure) when connecting to an Access Point
and select Ad-Hoc mode when connecting without an Access Point.
Double-click 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 DWA-520 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.
