I've downgraded to Windows 7 (from Windows 8) on my Aspire E1-531. Unfortunately, I don't know which driver to install for the wireless adapter — Atheros, Broadcom or Intel? I ran the hardware detection utility and it only displays results for VGA and LAN. Nothing about the wireless card.
In System > Device Manager > Other Devices, I have a listing for Network Controller which is looking for a driver (I assume this is the wireless controller since all the other drivers, devices, etc. are working fine).
I've tried installing each of the drivers, one-by-one, but no luck.
Does anyone have any advice on how I get the wireless working on this laptop?
