[ubuntu] Upgrade to 10.04 broke r8169-based wired ethernet (working only at 10Mbps) - Ubuntu Forums
What the heck? I was running Ubuntu 11.10 for the past two weeks and I go to reboot into Gentoo and my wired network no longer works!?! Found this post and another talking about shutting the system back down, turn off, unplugged, clear remaining power, and wait couple of minutes and plug back in. Well tada it worked, now what in the world did Ubuntu do to my onboard r8169 cards??
