I have apparently a simple issue but I've been so far unable to solve it. My system won't connect to the Ethernet connection automatically on start up, I have to manually click on Wired Connection 1
It is the only connection available under Networks and Connect automatically and Available to all users options are both checked. I've tried deleting the connection and letting it be created again, but still the same.
This started happening after I unplugged my router and connected it to another system. Before that the connection worked fine and started automatically, but after moving the router to another system and back this issue began.
My /etc/network/interfaces file reads:
iface lo inet loopback
