Setting up ad-hoc multiplayer on your PlayStation 3 allows you to play locally with another PS3 console without an internet connection. Here's what you need and how to do it.
Ad-hoc connections can be less stable than wired or infrastructure-mode wireless. For best results, keep consoles within 30 feet of each other with minimal obstructions. Some games may require specific port forwarding or UPnP settings. If you encounter issues, consult the game's manual or the PS3 user guide for model-specific instructions.
