This could be related with the e1000e driver power management bug that
was present in the 3.8 (raring) kernel. Basically, the ethernet card
couldn't detect carrier signal if it was on deep sleep state (e.g., the
laptop was on battery, not on AC).
I've uploaded a test kernel here:
http://people.canonical.com/~henrix/e1000e-pm-bug/
Basically, it contains the fix for the e1000e PM issue. This fix is already in
Raring kernel master-next branch, and should be released soon.
In the meantime, I'm tagging this bug as a duplicate of bug #1152194.
