This isn't the best way to get your PS3 on the net. If you do get it working with a cross over cable It wont be very quick. All network cables will be non-cross over by default, unless it is specified on the cable. You can tell by looking at the connector end, and look at the coloured wires. If they are in the same sequence at both ends (white/orange, orange, white/blue, blue, white/green, green, white/brown, brown) this is a normal network cable, if they are opposite at each end that is a cross over cable.
