How do I get an Atheros AR9485 wireless card working?

About a year before, I was having problems with that same Atheros AR9485 on my Ubuntu "Natty Narwhal". Back then, Ubuntu not even recognized that hardware as integrated to the computer. I purchased a cheap USB wireless network adapter that has worked excellent on Ubuntu; it has the form of a USB pendrive, and I connect it through an extension wire (I read that for health purposes is better to place it 15 cm. far to your body).

The name of the adapter is "Realtek RTL8187B WLAN Adapter". --it works pretty good in Ubuntu by just conecting it to USB port. If you buy an adapter, I recomend you to take your laptop to the store and ask to try the adapter right there before buying it.

Today I have upgraded to Ubuntu Precise Pangolin LTS and now the atheros works..., but with that same problems you mentioned. So I prefer to go back to my Realtek adapter. I did it by disconnecting the Atheros network and allowing the Realtek:

1----Connect the adapter on USB port

2----left click in the network icon (on the top right of your screen)

3----click on "disconnect" atheros

4----click on "connect" the Realtek adapter (or whatever wireless adapter you have)

There is another method, but I haven't try it:

1----Obtain the Windows driver for your Atheros network card. (You can download it in
the official website of your computer)

2----Locate the specific file that ends with ".inf "

3----Install "ndisgtk" --use your linux repositories--.

4----Open ndisgtk

5----Select "install new driver"

6----choose the location of your windows ".inf" file and click "install"

7----click o.k.

for more information on this method google: "ndisgtk"

I did all this comands and still not work - so I try just on the wifi using the keyboard combination FN+F2 | PROBLEM SOLVED
