Public bug reported: I am having trouble with my e1000 integrated ethernet port. The problem is intermitent, happens under Lucid, and not under Windows. The same problem happens on all three identical computers which are Dell Inspiron 530s towers.
Doesn't work, means that the port never acquires an ipaddress. I have tried 2 diffierent switches, from two diffierent manfacturers, af both work under Windows and not under Lucid. ethtool says that the card is MDI-X instead of MDI. Typing "ethtool -s eth0 autoneg off" fixes the problem until next reboot. I do need to restart "networking" and "network-manager" to get a ip afterwords though. I put this in rc.local as a workaround, but I'd really like a better solution: ethtool -s eth0 autoneg off service network-manager restart && true service networking restart && true sleep 3 Would looking at anything in a packet sniffer help at all? Also, Linux machines that are NOT Inspiron 530s work just fine.
