u dont need a network disc, ive got my slimline hooked up to net. all you do is plug ur ethernet cable into the back of ur ps2, and the other end in ur router or whatever, then go onto network on pes5 menu screen. u'll need to configure network settings on your memory card, but jus put everything as auto and yes and you shouldnt require a password or something it says from your internet provider. after that test ur connection and if it works your ready to roll
