When I did my first game I used an 80 foot crossover I made.
No I didn't make it just for that; its original use was to link my XBox with a buddy's so we could play Halo on two TVs from one side of the house to the other. Wireless was working okay, but every time the phone rang we would lag. Seeing how both my phone and my wireless run in the same 2.4GHz band…
Plus it was the only thing I had laying around at the time.
Never had any errors or probs with it, no errors or any thing. Only prob I had, was my buddy’s dogs chewed through the first one I made while I was over at his house once…
Just don't get a cable over 300 feet (100 meters), that’s when you will have real probs.
But remember the shorter the better.
