  1. wired device not managed
  2.  
  3. Most probably your interface appears in /etc/network/interfaces. By default, NetworkManager does not manage interfaces that appear in /etc/network/interfaces. You can change this behaviour.
  4.  
  5. To do this - in a terminal:
  6.  
  7. sudo nano /etc/NetworkManager/NetworkManager.conf
  8.  
  9. change the line managed=false to managed=true
  10.  
  11. Save, stop and start network manager:
  12.  
  13. sudo service network-manager restart
  14.  
  15. Alternatively, you can remove the interface from /etc/network/interfaces.
  16.  
  17. backup the current interfaces file:
  18.  
  19. sudo cp /etc/network/interfaces /etc/network_interfaces_backup
  20.  
  21. Then open the file:
  22.  
  23. sudo nano /etc/network/interfaces
  24.  
  25. Delete everything in that file and copy and paste the following:
  26.  
  27. auto lo
  28. iface lo inet loopback
  29.  
  30. Save, stop and start network manager:
  31.  
  32. sudo service network-manager restart
  33.  
  34. enter image description here
  35.  
  36. Double check in network manager (click on the indicator) that you have Enabled Networking ticked and you should also force deletion of old "wired connections" and selecting the new wired connection shown in the network manager indicator
