Trell,
You might want to use a standard ethernet cable, most newer cards can work and determine where transit and receive are automatically. I had several cross over cable that were actually missing several wires, I could not understand why they were not working correctly and I buzzed them out and low and behold several ways were not actually used in the cable. I got a standard ethernet cable that I tested on my home computer and pulled that in and all worked as expected. Just a thought.
