FC6/Dell Inspiron 8500: problem with eth0

[Jim Lowman <jmlowman@xxxxxxxxxxxxx>]

The FC6 install recognizes my network controller correctly as a 
Broadcomm 4401, but I get this message when I try to activate it:

error for wireless request   "Set Encode" (8B2A)   Set failed on device 
eth0; No such device

I know that the hardware is functional, because it works when I boot to XP.

FC6 was on this computer previously.  I reinstalled XP and FC6 after 
upgrading the HD from 40 to 100 GB.

Any help with my latest problem will be appreciated, as always.

Jim
