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.)
