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.

To do this - in a terminal:

sudo nano /etc/NetworkManager/NetworkManager.conf 

change the line managed=false to managed=true

Save, stop and start network manager:

sudo service network-manager restart 

Alternatively, you can remove the interface from /etc/network/interfaces.

backup the current interfaces file:

sudo cp /etc/network/interfaces /etc/network_interfaces_backup 

Then open the file:

sudo nano /etc/network/interfaces 

Delete everything in that file and copy and paste the following:

auto lo iface lo inet loopback 

Save, stop and start network manager:

sudo service network-manager restart 

enter image description here

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.
