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 or business. Strictly adhering to IEEE 802.11a/b, the D-Link

wireless family of products will allow you to access the data you want,

when and where you want it. No longer will you be limited to one location

or forced to run new wiring through your home or office. You will be able

to enjoy the freedom that wireless networking delivers.

A wireless LAN (WLAN) is a cellular computer network that transmits and

receives data with radio signals instead of wires. Wireless LANs are

used increasingly in both home and office environments. 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 has proven to be beneficial for many users.

Wireless users can use the same network applications they use on an

Ethernet LAN. Wireless adapter cards used on laptop and desktop

systems, support the same protocols as Ethernet adapter cards. For

most users, there is no noticeable functional difference between a wired

Ethernet desktop computer and a wireless computer equipped with a

wireless adapter other than the added benefit of the ability to roam within

the wireless-cell. Under many circumstances, it may be desirable for

mobile network devices to link to a conventional Ethernet LAN in order to

use servers, printers or an Internet connection supplied through the

wired LAN. A Wireless Access Point (AP) is a device used to provide this

link.

People use wireless LAN technology for many different purposes.

Mobility - Productivity increases when people have access to data in

any location within the operating range of the WLAN. Ad-hoc

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, both physically

and logically, can benefit from WLANs ease of implementation. WLANs

can operate in locations where installation of wiring may be impractical.

Furthermore, IEEE standardization mandates interoperability of all

WLAN devices that conform to the 802.11a/b set of standards.

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.

Wireless Basics (continued)

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 allow roaming over a broad area.

Wireless Basics (continued)

Installation Considerations

Designed to go up to 1650 feet (~500 meters), D-Link DWL-AB520 lets

you access your network with your computer 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:

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 Wireless product’s range from 3-90 feet (1-

30 meters.)

For some businesses or for a large residential home deployment, it

may be beneficial to have more than one access point with

overlapping coverage.

2. Be aware of the direct line between Access Points and computers

with wireless adapters - 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! Try to make sure

that the Access Points 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. Try to position

Access Points, and computers with wireless adapters 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 or 1-2 meters) from

electrical devices or appliances that generate extreme RF noise.

Wireless Basics (continued)

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 computers with wireless adapters 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.

Using radio frequency (RF) technology, WLANs (Wireless Local Area

Networks) 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.

Getting Started

To begin, select the type of wireless network you will be building.

We will discuss the following types of networks in this section:

1. A Home Internet Network

with A Residential Gateway/Router

Troubleshooting

This chapter provides solutions to problems that can occur during the

installation and operation of the DWL-

AB520 Wireless PCI Adapter.

Read the following descriptions if you are having problems.

1. The computer does not recognize the DWL-AB520 802.11a/b

Wireless PCI Adapter.

• Make sure that the DWL-AB520 Wireless PCI Adapter is properly

seated in the computer’s PCI slot.

• Check that the DWL-AB520 is installed in a 32-bit PCI 2.2 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:

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 NetA3x.inf and A3ax.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 certification into oem.inf files (e.g., oem1.inf.)

2. The DWL-AB520 802.11a/b Wireless PCI Adapter does not work

properly after the driver is installed.

• Restart the computer. (In some cases, it will be necessary to

restart the computer after installing the drivers.)

• In Windows XP, go to Start>Control Panel>System>Hardware

Tab> click on the Device Manager Tab> click on Network

Adapters> double click on D-Link DWL-AB520 Wireless PCI

Adapter> make sure that “This device is working properly” is

displayed under Device Status under the General Tab. (Please

refer to Checking the Installation of the Drivers for the

Wireless Adapter in the Networking Basics section of this

manual for more information.)

Troubleshooting (continued)

• If the device is not working properly and a yellow exclamation

mark is displayed, then there is probably a resource conflict. In

this case, make sure the computer system has a free IRQ and if

necessary, uninstall the drivers, restart the system, and repeat

the driver installation procedure.

3. The computer with the wireless adapter installed is unable to

connect to the wireless 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-Link products is Default. (Please refer to Checking the

Wireless Configuration in the Networking Basics section of

this manual for more information.)

• 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. (Please see the Status Tab in

Linkmon in the Configuration Utilities section or see Checking

the Wireless Configuration in the Networking Basics section

of this manual to learn more about BSS-Basic Service Set.)

• 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 network

connection icon in the taskbar > click on Properties > click on

Configure > select the Settings Tab > click on Modify to change

the settings for the wireless adapter. (Please refer to Checking

the Wireless Configuration in the Networking Basics section

wireless connection will not be established in Infrastructure or

Ad-Hoc mode if Turbo Mode is enabled on one end of the

wireless connection and not the other. (Please refer to Checking

the Wireless

Troubleshooting (continued)

Configuration in the Networking Basics section of this manual

for more information.)

• If Enable Security is selected, make sure that the correct

encryption keys are entered on both the wireless clients and the

access points. (Please see Checking the Wireless

Configuration in the Networking Basics section of this manual

for more information.)

4. The wireless client cannot access the Internet in the

Infrastructure mode.

•• Make sure the wireless client is associated and joined with the

correct Access Point. To check this connection: Right-click on

the Networking Icon in the taskbar> select View Available

Wireless Networks. The Connect to Wireless Network screen

will appear. Please make sure you have selected the correct

available network, as shown in the illustrations below.

•• Check that the IP Address assigned to the wireless adapter is

within the same subnet range

as the access point and gateway.

To check the IP Address assigned to the wireless adapter,

double-click on the Network Connection Icon in the taskbar >

select the Support tab and the IP Address

will be displayed.

(Please refer to Checking the IP Address in the Networking

Basics section of this manual.)
