Yes three clicks of the mouse and it is connected again so no real difficulty.
really?
how do you do that? 
can you try with a different ethernet card?
in pcc, network & internet, network center what do you have?
One click on the NetApplet icon in the tray brings up Network Centre
One click to expand the connection
One click on the Connect button ...... and it is up in maybe three or four seconds.

A fourth click closes Network Centre.
It is not important enough to change NIC cards or any other hardware.
It functions fine ..... just not connected at boot up, despite the setting being selected during creation of the connection.
No need to spend time over it ....... I was really just wondering if any one else had seen this or if it is peculiar to my setup.
regards.
