I was messing around with my network settings yesterday in order to talk to a piece of medical equipment but when I came into work this morning, network manager had stopped managing the network adaptor.
There was a network manager update for Karmic yesterday that might have caused this, but it was probably me messing about.
The fix is easy enough though
sudo nano /etc/NetworkManager/nm-system-settings.conf
Change “managed=false” to “managed=true”
Restart
Solution from Launchpad
