Comment 53 for bug 86798

I also see the same problem, on a newly built box which has never run windows. Connectivity seems intermittent - the network cable is plugged in all the time, and sometimes it will boot up with a working network, other times nothing. Unloading and reloading r8139 fixes the problem.

Asus P5Q SE motherboard, with built in RTL8111/8168 B PCI Express Gigabit Ethernet Controller.
