ya i have internet and all just cant connect to the playstation network
Hmmm... Okay. Try unconnecting your internet from the PlayStation 3 in the Settings>Network Settings>Internet Network Settings, then you can try removing the internet connection and re-connecting it.
ya not working i even get on my dads playstation and he can log on but then i try logging into mine on his playstation wont let me , stupid playstation network
Okay, if you're still having trouble get on the PlayStation Network, you can try calling Sony. 1-800-345-7669
It is an unknown error code. While searching, I couldn't find an exact reason for it/definite solution.
You could always try going into "Safe Mode" and selecting option 3.
See if that helps. Worth a shot.
