From what I recall, some game servers have been shut down. Final Fantasy 11 just shut down their servers after 14 years in March, to play online in certain games that are down, you need to do something with xlink, and yeah you probably need the network adapter startup disc to configure it and as for the hard drive, make sure the hard drive is formatted for the ps2 itself, which you can do with a hard drive format utility disc, which u can find online too
