I think I got it! It seems to be correlated to the use of the nic too soon from login. E.g., I start the computer, login appears, enter user/pass, as soon as the desktop appears I start Thunderbird: Ubuntu network stops working. Shut down the system (or reboot in recovery to make the NIC reset as explained in the first post), test again this sequence and it behaves the same way: network freezed. Shut down the system (or reboot in recovery to make the NIC reset as explained in the first post), login, and this time I wait few seconds befor opening Thunderbird: A-OK! All engine runnings! We have a lift off! :-)
Try this on your machines and see if the problem is for all or only for some hardware. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/746579 Title: Network stop working and soft reboot is not sufficient -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
