solved by editing a different (but similarly named) file in LinuxMint

Clicking on it shows that all interfaces are in "unmanaged" mode so that Network Manager has no control over them. This occurs without the user making any changes to the interfaces. User has not manually set the devices into unmanaged mode. How to correct it in the Network Manager -> Edit Connections dialog is unclear. Details: $ cat /etc/network/interfaces auto lo iface lo inet loopback iface eth0 inet dhcp auto eth0 iface wlan0 inet dhcp wireless-key XXXXXXXXX wireless-essid XXXXXXXXXX To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/280417/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
