Public bug reported: Seems that network manager crashed on a Lenovo laptop. Nothing shows in network manager panel expect "Enable networking"
Try toggling that and restart networking. Nothing. ifconfig only shows loopback Add this to /etc/network/interfaces: auto eth0 iface eth0 inet dhcp Restart networking service and it comes on. Restart PC and the connection is gone again but the manager dropdown now lists wlan and can connect on wlan as a workaround. Still no eth0 ** Affects: network-manager (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1506305 Title: eth0 suddenly lost and won't come back To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1506305/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
