Introduction

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 802.1 1b products.

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.

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)

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+

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.

802.11g of fers 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 1Mbps in the 2.4GHz range.

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 objects 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 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.

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.

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.

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

Getting Started

With its default settings, the DWA-520, when activated, will connect

with other D-Link AirPlus Xtreme G products, right out of the box.

There are basically two modes of networking:

Infrastructure – using an Access Point or 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 DWA-520 wireless network 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 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 Xtreme G DI-624

A desktop computer with a wireless adapter -

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 sets 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.

Troubleshooting (continued)

2. I cannot connect to the Access Point or the Wireless Router.

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. Refresh the DWA-520 Utility

3. The DWA-520 Power and Link lights are not on.

Check to see if the DWA-520 PCI adapter is firmly inserted into the PCI

slot of your computer.

4. I forgot my Encryption key .

Reset the Access Point to its factory default settings and restore the DWL-

G520 Wireless PCI Adapter to the factory default settings. (The default settings are listed in the Using the Configuration Utility section in this manual.)

5. The computer does not recognize the DWA-520 Wireless PCI Adapter.

Make sure that the DWA-520 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:

Page 42

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 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.)

6. The computer with the DWA-520 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 Point s. 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.

Page 43

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. 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.

7. How can I troubleshoot distance issues using the DWA-520.

Move the DWA-520 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
