hi Joseph, 3.8.0-12-generic 3.8.2-030802-generic 3.9.0-030900rc2-generic
I tested all the kernel above, the same symptom. However I realized it doesn't need sleep/wakeup. And it works on exactly the same cable and doesn't work on any other one. I tested a couple of them at my workplace. They are on the same network. ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed ** Tags added: kernel-bug-exists-upstream -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1131091 Title: LAN cannot be connected after wakeup To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1131091/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
