I just installed Ocelot on my new machine (with an ASUS M5A99X EVO motherboard and on-board gigabit ethernet), and I asked it to download updates while it installed. The install took forever, the longest part being the download of updates, which should have been my first clue. Post install, accessing the internet is sketchy at best, but mostly just broken. The adapter consistently fails to pull down down an ip address or the DNS addresses from my router.

I should also note that I know this isn't a hardware problem, because I can boot into Windows 7 (dual boot), and the ethernet works just fine. Actually, blazing fast might be a better word. But there are many things (primarily software development) that I need to do in Ubuntu instead of Windows.

I feel that it is a driver issue, but I don't even know where to start, since I've always just relied on Ubuntu to install the correct driver automatically for me. Why would the driver be wrong, and what should I do about it?
