at bug #83143 someone told about: disconnect network cable and re-plug it and then paste the result of a : dmesg |grep link
and this is what i got: [ 12.413843] audit: initializing netlink socket (disabled) but without the grep help i can get the link up and link down information: [ 1578.601659] e1000: eth0: e1000_watchdog: NIC Link is Down [ 1587.888119] e1000: eth0: e1000_watchdog: NIC Link is Up 100 Mbps Full Duplex maybe it's something setup wrong with the network-manager to get messages about link up and link down. -- Wired connection not detected (Worked nice on Beta) https://bugs.launchpad.net/bugs/109496 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
