Fedora 16 killed my eth0 ?

['Chris Hall']

Once upon a time I was happy with Fedora 14.

Then my hard disc crashed, and I thought that was an opportune moment to move up to Fedora 16.

Big mistake.  Huge.

Cannot stand the new Gnome.  So I'm trying KDE.

More important.  Somebody has killed my eth0.  It's gone.  "Device eth0 does not seem to be present..."  I cannot find it anywhere.

Help !

Thanks,

Chris
