Public bug reported: This is a curious one and all administrative attempts to narrow down the source of the problem failed. The symptoms:
- When booting off the Live CD, network is running just fine. - After installation, on the first boot, too. - After another reboot, ethernet doesn't work at all, DHCP doesn't pick up. Further investigation: - To satisfy the connection indicatior in the top Gnome menu bar, I can set up ethernet manually with the default-installed tool (network- manager-gnome?). Still, pings to computers in the same network report "Destination unreachable". ifconfig, in turn, reports what I'd expect for a working ethernet device, IPv4 and IPv6. - Attempts to blacklist ipv6 failed, but that's another story. Workaround Just by chance I found this report in german which describes pretty much what I experienced: http://computerverein-rostock.de/viewtopic.php?f=2578&t=58386 At the bottom you see a screenshot from MS Windows. He explains how enabling Wake-On-Lan in MS Windows solves his networking problems in Ubuntu. Exactly as it did in my situation.
