am experiencing the same issue it seems running 11.04 64bit, have a RTL8111/8168B network card
I seemed to be able to "fix" it by unplugging/plugging in the network cable a few times and then it would suddenly connect this had to be done every startup now I found a workaround through this link: http://ringlord.com/news-20110429.html I added following command to /etc/rc.local ifconfig eth0 down sleep 10 ifconfig eth0 up sleep 10 ethtool -s eth0 port tp and now my 11.04 is connected automatically before I'm logged in (so when it's still on the logon screen) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/573259 Title: Ubuntu 10.04 makes RTL8111/8168B network card unusable until cold reboot -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
