so i installed windows 7 onto my Acer Aspire AOD255-2331, and i went to their website to download and install all the drivers, but there is one problem. I cannot turn on the wifi. It is normally controlled through keyboard shortcut of fn+f3, which doesn't work. what kind of driver is for those shortcuts? or is there another way to turn it on? (i checked there is no physical switch for it on the comp).
