I can confirm that Feisty's NetworkManager indeed misbehaves when there is more than one network card present. I have two cards, one connected to public internet, one is for my home network. Only one card works at the time, I can even use NetworkManager to choose, which one.
As others have noted, temporary workaround is to execute "sudo /etc/inid.d/networking restart" after each boot. It is pain in the... you know, where. -- Feisty network-manager 0.6.4-6ubuntu3 update killed NIC https://launchpad.net/bugs/92085 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
