I upgraded from xp to win 7 on my Acer Aspire One 532H, I choose to format my driver to start with a clean computer. I tried to connect to wifi but I couldnt, turns out my wifi driver got deleted, I download the driver and I ran the setup but its still not showing up in device manager. The wifi driver is Atheros 18.104.22.1689. Ive tried everything and I cant use the ethernet cord forever. Please help.
