Windows 8.1 and Qualcomm Atheros AR9485 Adapter - No Wifi Connections - Fixed but wanted to share

I recently did the update to Windows 8.1 and it was wonderful.

 

Except it destroyed my wireless network.  After trying several APs/routers, and as many drivers as I could find, I was at my wit's end.  Nothing worked.  When I tried to connect to my AP, it would start Verifying, and then the keyboard indicator light  for Wifi would suddenly change from white to orange, and then back to white.  It couldn't ever connect.

 

I ended up misclicking on a different AP and it magically connected.  Wow, strange, right?

 

So I started digging.  At least in my case, if you have an Atheros based AP (my primary is a DLink DIR-615), and are trying to connect when the network type is set to N-only, this adapter cannot connect.

 

I changed mine to "NG-Mixed" and it connected.  I didn't have to change other settings.

 

So if you have a similar problem with that specific chipset (AR9485) take a look at your AP/router and see if your network mode is N-only.

 

Hopefully I'll save someone else some major headaches here.

 

Cheers!
