To remove the newly installed driver from the system if the system does not have previously installed versions of the NDIS driver, proceed to Step 4. To remove the NDIS driver from the OS, go to Device Manager, right-click Atheros AR500x Wireless Network Adapter, and choose Uninstall. Click OK to uninstall the device. When the device is uninstalled from Device Manager, search for and delete the driver files that reside in the system. Go to the Start menu and choose Search > For Files or Folders. Enter oem*.inf in the Search for files or folders named: field, and enter Atheros in the Containing text: field. Click Search Now. A few files matching these criteria are possible, if previous drivers have not been removed properly. Choose the files that have been found and delete them from the system. To complete the uninstallation, remove the file ar5211.sys from the folder \WINNT\system32\drivers.
