Aurora R1 Ethernet Cable Not Detected Problem

I have an Aurora R1 with the Broadcom 5784 NIC chip.  System info says the driver/chipset are working fine but the ethernet cable is not detected.  I have confirmed operation of the Router (ASUS RT-N66U) and cable with my laptop.  I have re-installed the driver from Dell and tried a newer driver direct from Broadcom.  The LAN is enabled.

System:

i7-980 (upgraded from i7-920); GTX-260; 500 GB main HD; 2 TB RAID; 300GB Raptor drive

Recently I upgraded to Win7 Pro 64-bit from Home Premium but noticed no issues.  We did have a recent severe thunderstorm (close lightening strikes) but the Aurora was off but the router was on and active.  I left town for a couple of weeks and I do not recall if I started the PC after the storm.

I have googled this issue but what I found is over one year old and with no resolution.  Any help is appreciated. 

Thanks, Chris
