I have what I think might be the same problem on a new installation of Lucid (which I chose for LTS reasons).
After install, my AR8152 v1.1 wasn't available through NetworkManager. After some investigation, I installed linux-backports-modules-wireless- lucid-preempt to try to get a working atl1c module. Then when I booted into 2.6.32-30-preempt (which wasn't the default in GRUB), eth0 appeared in NetworkManager. Unfortunately, DHCP failed. I tried manually setting IP information, which sort of worked. When I ping my gateway, some packets get there and back, but very few: PING 10.34.55.1 (10.34.55.1) 56(84) bytes of data. 64 bytes from 10.34.55.1: icmp_seq=8 ttl=64 time=0.149 ms 64 bytes from 10.34.55.1: icmp_seq=50 ttl=64 time=1.35 ms 64 bytes from 10.34.55.1: icmp_seq=65 ttl=64 time=0.156 ms ^C --- 10.34.55.1 ping statistics --- 69 packets transmitted, 3 received, 95% packet loss, time 68000ms rtt min/avg/max/mdev = 0.149/0.554/1.358/0.568 ms The same ethernet cable to the same gateway does perfect pings every time from an older laptop running Fedora 13. ** Attachment added: "Output of lspci -nnvv on Tim's laptop running Lucid with linux-backports-modules-wireless-lucid-preempt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/754752/+attachment/2044252/+files/lspci-nnvv-tim -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/754752 Title: [driver: 'atl1c' ifindex: 2] When I plug ethernet cable after system boot eth0 still down :( -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
