The same thing happened to me when i got the game. I had one of the old old ps2s, and played for a while unitil i kept on gettin the disk read error. I tried the laser cleaner CD thing but didnt help, but i used the same netowork adapter and stuff. It wasnt until that i found out that the laser probably got bumped out of place. You could maybe get that fixed, if thats the problem, somewhere(no idea where though). But even if you did buy a new PS2 you woulndt need a new adapter. And like the posts above me, try to keep dust our of the PS2, by sucking it out of the filter thing(dont blow in because that just puts it in there)
Hope this helps
