Go to this website and try the drivers there.http://www.realtek.com/downloads/downloadsView.aspx?Langid=1&PNid=24&PFid=24&Level=4&Conn=3&DownTypeID=3&GetDown=false#1
Download one of the 64-bit versions from the list. (I had a lil trouble fiding how to download, but once I actually read what each column was, I figured it out. They're all the way to the right. CN, UK1, US1, etc.... Either me being dumb or maybe a problem someone else would have.)
If you're not sure how to do it, download the README file that is in the same list as the drivers. If THAT won't help, just post on here and let me know. I hope that this helps!
