I own an old PS3 that can play PS2 games ( www.gamestop.com/Catalog/ProductDetails.aspx?product_id=64006 ) and I've never connected it to the internet. I tried today, using a wired ethernet connection. I tried to sign up for the Playstation Network (LittleBigPlanet said I needed to to go online), but I got a DNS error, number 80710102. Repeated tries gave the same results. I looked on playstation.com, but the troubleshooting page confused me and I am unsure of what I should do. I would try to download the newest system update, but I am afraid that it would take away my ability to play PS2 games. Help please!
It might be your connection. I use Wireless Connection, it might not be as reliable; but it works. Using pure internet connection sometimes doesn't go as well as the Wireless, but that might be me. :/
Wired Connection is better than the Wireless. As for the error I think you either need to update your software or check your network settings. if you need further help feel free to message me and ill tell you how im set up.
if its a 60GB than it would play ps2 games even if you update the system.So JUST UPDATE THE THING AND I GARENTEE YOU IT WILL STILL PLAY PS2 GAMES AND IF IT DOESNT WELL AT LEAST YOU CAN PLAY PS3 GAMES,RIGHT
