Well, it looks like you have a fatass ps2 since you've had one since it's came out. You need to buy a network adapter, I can't remember how much they cost, I think around $20-30. Then you just plug in a phone cable or ethernet cable into it, load up a game that can play online, go to network play, and configure it correctly. If you have broadband and a router, like I do, try just checking everything that says automatic.
