just downloaded window 8. my wifi isn't working so i went on acer's website to download drivers (i have a Aspire M5-481T) the acer upgrade assistant tool fails in downloading the RealTek part of the downloads and when it comes to instillation...just keeps saying it's installing when really it isn't (let it on overnight and nothing had changed). i decided to download the drivers one by one off acer so i started with the wifi's and even those weren't able to install properly! what is going on?

ps. i don't know a whole lot about computer os's so dumb it down for me
