What all does it take to hook up PS2 to my computer, I have router, and all that stuff?

I have some extra Ethernet wires, do I need anything other than that? Do you have to have something special for this? I know I am kind of new to the PS2 online thing, I know I need to get with the times they already have ps3, Anyway just let me know if I have to buy anything extra I technically know how to physically hook them up, just dont know what I need to get? Thanks in advanceWhat all does it take to hook up PS2 to my computer, I have router, and all that stuff?
hopefully this will point you in the right direction..





if an old PS2 (with CD tray loading of games). then you need a network adaptor


slim ps2.. this is built in.





both - need the network adaptor disk (this may come with some games ??).. i think i got this posted to me when i registered with playstation on-line...comes with a driving/shooting game





i seem to remember it took a few goes to get the network disk settings to do their thing
