athurx is the atheros wireless driver, i have 2 atheros adapters on the same computer, one is 300Mb/s and the other is 150Mb/s
The reason for the blue screen is that the wireless interface driver(S) on my 64bit windows 7 (could be on any other platform too) is outdated, and it seems the old version of the driver has a problem in using 2 different atheros adapters on the same computer, the solution seems to lie in updating the drivers.
1- The Wireless N 150Mb/s (TP-LINK TL-WN722N, atheros AR9271 chip, should also apply to TL-WN721N that uses the same chip)
So, my atheros based TP-LINK TL-WN722N uses the Qualcomm atheros AR9271 chip, Windows installs driver version 188.8.131.52 dated 1/4/2010, and since Qualcomm atheros does not provide their drivers directly on there website, i downloaded the driver from TP-LINK, the new driver had version 184.108.40.206 and was dated more than a year later 4/20/2011, the problem with this driver is that it is NOT SIGNED, and therefore you have to manually install the driver then agree to install a non signed driver, simply asking windows to update from a directory will not update your driver, also check the driver versions before you update to see if your drivers have been updated.
2- The Wireless N 300Mb/s (tp-link TL-WN821N, Atheros AR7015)
This one also has an outdated driver that can be updated from the TP-LINK website, just like the one above.
Make sure you unplug the other driver as you update the software for the first, and once both have drivers installed, reboot and plug in both adapters, works like a dream up to now.
