I want to network my old win95 comptuer wiht a 98 one. i've got two 10/100 network cards with RJ45 plugs. One comptuer is in the shed, and the other in the house, and i want to put plugs in the walls to amke it look all nice and tidy etc. I was told that only one of the leads from computer to the wall needs to be a cross over cable, and the rest straight. Is this correct??
