Thanks very much Ryan, that has fixed it.
My wife has Parkinson's so she must have accidentally hit this icon when
shutting down - it is very close to the shut-down etc icon. Funny enough
this particular icon is not present on my machine on the toolbar top
right hand side.
The same connection editing screen can be reached by 
System>Preferences>Network Connections.
Thanks very much again, I have learnt something.
Cheers
David
