Hi Marc, Please attach /etc/network/interfaces.
Ref: In `man networkmanager.conf` managed=false | true Controls whether interfaces listed in the 'interfaces' file are managed by NetworkManager. If set to true, then interfaces listed in /etc/network/interfaces are managed by NetworkManager. If set to false, then any interface listed in /etc/net‐ work/interfaces will be ignored by NetworkManager. Remember that NetworkManager controls the default route, so because the inter‐ face is ignored, NetworkManager may assign the default route to some other interface. When the option is missing, false value is taken as default. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/827491 Title: [Inspiron N7110] Ethernet is unmanaged To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/827491/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
