If you dont mind, can reformat and use windows 8.

If you dont want reformat, download the drivers, go remove old drivers from device manager. uninstall whatever program u used to install drivers

restart in save mode and install the drivers you download earlier

I tried clean format to win 8 but still unable to turn on wifi capability. I am still only able to use Bluetooth and use internet via Ethernet cable only, cant use wifi to access internet.

Suspect your laptop has a white list that restrict wifi cards.

But I thought Acer don't have whitelist? Any way to bypass the whitelist with mod bios?
