Troubleshooting (continued)

2. The computer does not recognize the DWL-520 802.11b Wireless PCI

Adapter.

• Make sure that the DWL-520 Wireless PCI Adapter is properly

seated in the computer’s cardbus slot.

• If Windows does not detect the hardware upon insertion of the

adapter, make sure to completely remove drivers that were

previously installed. 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 NetA3AB.inf and A3AB.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.)

3. The DWL-520 802.11b 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 Wireless LAN Card(RTL8180)> 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.)

• 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.
