I bought a Computer Network Cable from RadioShack. It says Category 5e. Is it suppose to be used for the routher method or the crossover method? I tried to use it as a crossover but it didnt work. Do i have to be connectec to the internet to use the crossover method becasue I only have one port to put it in and I already have a ethernet cord in that port. Also I was wondering could I do it on a computer thats connected to the internet using a wireless adapter?
