I need to make an ethernet cable to run to a computer 50-100 feet away from a router. We have CMX cable, which looks identical to CAT 5. Same shield, same number of wires, etc. Anyone know if it will work? If there's a definite "No". I won't waste the cable trying it, but if we can save some money, I'd rather use what we have. We're a non-profit House, so pinching pennies wherever we can is a plus.
