LAN/NIC problem

I did cut the wires on a cat6 cable per his instructions, but did not work for me.

You may have cut the wrong wire.  

... the white wires with the trace coloring are difficult to see ( some vendors are worse than others ) and of course you should have good lighting.  My first guess is that the wrong wire was cut, and the other guess is that your cat6 cable might be defective ( one of the green or orange wires might have a break in it ).

On my cable I actually pulled the wires from their sheath. I cut the blue and brown pairs and physically pulled the wires from the cable, and resealed the cable with shrink wrap; worked fine. 

It pretty much has to work; unless you cut the wrong wire.
