Ummm... you said you installed "many" atheros drivers?
There is probably only one that actually works.
Go to Control Panel>System>Hardware>Device Manager and double-click on the atheros wireless device, then click the "Details" tab. Come back with the string of numbers and letters you see and I'll see about getting you the correct driver.
Note: What you will see is "device instance ID" and the box will show "PCI\VEN" and a lot of gibberish. That string of characters is what I need to help you.
