What does your wi-fi have to do with your audio and video drivers??

What driver are you trying to install?

Are you getting the drivers from http://support.acer.com/us/en/product/default.aspx?modelId=2076? There are 3 audio drivers listed, did you try all of them, or the latests one?

And make sure you download the right 32 bit or 64 bit drivers.
