Ok everybody, I know this is an old thread but I've had to deal with this driver failure just as recently as 2 days ago.
My system was behaving just as everyone has indicated...slow as slow could ever be!....nothing works.....reinstall several times doesn't rectify the situation.
Fear not, I've found the fix.
You have to clear your Real Time Clock (RTC) Ram in the CMOS. The RTC Ram holds this like the time and date but also includes things like startup information.
I dug thru the manual until I stumbled upon the walk-thru on page 2-19. If you can't find your manual or don't have one your only option is to look online and as you can't install the driver to do that I'll attempt to provide an explanation of where it is and what to do.
DISCONNECT POWER CABLE BEFORE ATTEMPTING THIS OR FRY YOUR BOARD! You've been warned.
1. Remove the on-board battery.
2. Directly to the right of the battery (this assuming you're looking at your board the right side up) you will see a blue jumper covering
the CLRTC. Remove the jumper from pins 1 and 2 and place over pins
2 and 3 for 10 seconds.
3. Reinstall the battery.
4. Plug in power cord and turn on computer.
5. Hold down the <Del> key during the boot process and enter BIOS
setup to re-enter the CMOS data.
6. Reinstall Windows and this time you'll have no problems with the
Atheros drivers.
PEACE
