That doesn't completely work. I deleted the file and rebooted. The file was 
recreated and now it says eth0, but:

- the network still does not start automatically (I have to click the 'System 
eth0' icon in the system tray in knetworkmanager)

- I still don't get my old IP address, which is vacant. I am still getting a 
different one that the default one I had on my local network.
