Lost eth0 after taking regular upgrades

[molly.moggins]

I have been running 12.04 for a while now and today I have a problem which seems to have arrived with the latest set up updates via update manager.

I have no internet connectivity at all and ifconfig no longer shows an entry for eth0, my wired connection.

When I use the system settings tool under Network I get an error message saying "network services are not compatible with this release" which flashes up in a box after I see a brief message saying that my network cable is unplugged - which it isn't.

I am forced to use a Windows laptop to access the internet and I have no idea what to do about fixing this.

I saw a suggestion elsewhere that I should install wvdial which I did and I ran wvdialconf but that told me it was unable to detect a modem.

I am not sure that was about my problem anyway.

I am also posting this in the Networking forum.
