So I reinstalled Windows 7 on my Lenovo B560. I installed all the drivers (and the wireless one), but the wireless connection icon does not even appear and it does not work. As my Ethernet driver is Atheros, I think that my wireless driver is Atheros as well. But after installiation, it still not work. I can't find that driver on device manager or anywhere else, except the folder in program files. Don't know what to do. What could you suggest?
