error 80710102

Hey, I think I´ve read a lot of forums about this problem and can´t see how to solve it, the thing is, I just got a Modem ( no router here) so, I was

just surfing the web and it was ok and then I hooked my ps3 and played with no problems for about 2 hours (killzone 2 and COD4) with the automatic

settings but then I quit playing and I tried later to play again but this damn error keeps showing, I tried all the stuff that people say but I can´t get to work, need help, thanks!!!

You could try power cycling the modem and see if that helps.
