After a horrible experience with my RaLink RT 3290 wireless adapter over the past two years, I recently purchased a TP Link WN722N external adapter. Ever since I have been using it, my system crashes now and then.

I downloaded the latest drivers for the Atheros 9271 chipset which it has inside it. The driver upgrade has minimized the BSOD's to once every two days but it still occurs.

What options do I have? My internal adapter is a piece of crap. HP itself admits it. I don't want to replace this TP Link device since it works great and has an external antenna as well, giving excellent speed.

BlueScreenViewer supports this claim. It's the athuwbx.sys causing bluescreen:



I found the solution to this and would like to get back here.

On Windows 10:

DO NOT use the latest driver provided on https://www.atheros-drivers.com/atheros-wireless-drivers.html

DO NOT use the driver and utility included inside the installation disc.

If you have use any of the above sources to install the driver and/or utility, use the Control Panel to uninstall them both. Also open Device Manager, right click the Atheros WLAN adapter and make sure the driver is uninstalled.

Then download the driver through Device Manager itself. It's a bit old (2010) but will not cause BSOD.

    in the list I see a TPlink 150MBit device – magicandre1981 Sep 11 '16 at 7:38
  • That's interesting, although there are other TP Link ***N devices, for example the WN 727N, which I believe uses RaLink chipset. Better not take a risk when I've had the problem solved with the older driver :) Thank you for the help anyways! – U. Muneeb Sep 11 '16 at 16:45
