I can confirm that something is definitely wrong with wired (at least) connectivity in Jaunty. Did not experience this in Gutsy, Hardy or Intrepid. I have three desktop machines which are connected by wire to the Internet. Over the last few days, each one of these has disconnected from the 'net and is dead in the water. Of course, I can't SSH in to restart them, so I need to get physical access to them. Here is what I found in syslog:
May 4 03:37:40 XXX NetworkManager: <info> DHCP: device eth0 state changed renew -> expire May 4 03:37:40 XXX dhclient: DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 5 May 4 03:37:40 XXX NetworkManager: <info> DHCP: device eth0 state changed expire -> preinit May 4 03:37:45 XXX dhclient: DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 5 May 4 03:37:50 XXX dhclient: DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 10 May 4 03:38:00 XXX dhclient: DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 11 May 4 03:38:11 XXX dhclient: DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 11 May 4 03:38:22 XXX dhclient: DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 10 May 4 03:38:32 XXX dhclient: DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 9 May 4 03:38:41 XXX dhclient: No DHCPOFFERS received.

May 4 03:38:41 XXX NetworkManager: <info> DHCP: device eth0 state changed preinit -> fail May 4 03:38:41 XXX NetworkManager: <info> (eth0): device state change: 8 -> 9 May 4 03:38:41 XXX NetworkManager: <info> Marking connection 'Auto eth0' invalid.

May 4 03:38:41 XXX NetworkManager: <info> (eth0): device state change: 9 -> 3 May 4 03:38:41 XXX NetworkManager: <info> (eth0): deactivating device (reason: 0). It seems that something goes wrong when the IP address is being renewed? I think this only happens on idle connections. ** Changed in: network-manager (Ubuntu) Status: New => Confirmed -- Wired Network Disconnected after upgrade from Intrepid to Jaunty https://bugs.launchpad.net/bugs/368709 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
