cable

I have a wired network connection that worked fine in version 11.10. I upgraded to 12.04 and immediately after the upgrade was completed, the OS reported my "cable unplugged". It is not unplugged and it is not defective. I have a D-link DFE-530TXS 10/100 ethernet NIC and I see what seems to be the generic 10050 driver loaded. Is there any way to just flush anything and everything to do with the network configuration and have Ubuntu reset/find everything again? If not...is there any way I can get it to realize that my network cable is not unplugged? (considering it worked mere minutes before).

Thanks.
