Things You'll Need
Instructions
For a wired connection, connect your PlayStation 3 to broadband internet with an Ethernet cable. The Ethernet port is located on the back of the system. For Wi-Fi, you will need an internet-connected wireless router. If your wireless router requires a password for access, you can enter this password in the "Network Settings" menu on the Cross Media bar.
Insert any game with online functionality into the PS3 console (check the back of a game box to make sure you can play that particular game online).
Select the "Sign Up for PlayStation Network" icon on the Cross Media bar. Input the requested information to complete your registration. Unlike Xbox Live, using the PlayStation Network is free of charge.
Start the game and access the main menu. You should see a "Multiplayer" or "Online" option. Select it and enjoy the online community experience.
