After further testing, I finally encountered an error: the ethernet chip not being activated at all (slow blink on ethernet switch, no connection).
However, to my surprise, I was able to fix it by issuing the commands: sudo rmmod r8169 sudo modprobe r8169 No turning off at the wall, or even rebooting needed. (The first command may not have been necessary.) It's kept the correct MAC address throughout. I wonder if this is connected with booting between other distros. I've had it happen occasionally in the past when I was playing with Puppy linux and running Hardy as my main OS. -- r8169 ethernet MAC address changes in 2.6.32 kernel https://bugs.launchpad.net/bugs/562742 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
