Yes, please & thank you.  And maybe look at the tests that determine its bad 
and has to be fixed.  IMO, something fubar in the later bios versions is 
getting by that test.  Results are extremely unstable with either the 1604beta 
or 1701 versions of that bios.  1502 does trigger the fix, and the fix is pure 
gold.

The nic's (2 of them) are in the motherboards MCP55 chipset according to what 
I have been told.
