Are you using a wireless router sometimes i have to reset mine to get it to sign in , I ran a cable into the PS3 and now it works fine.

Im using a cable from my router. Sometimes it works and sometimes it doesn't but sure hey! Must try it again actually. Been too busy playing fm 08!

Just tried it again and now i can't sign in at all!

I've done an internet connection test and it says
Obtain IP address-succeeded
Internet connection- succeeded
Playstation Network- Failed

I don't know what to do!
