If you have a router that the computer is connected to look for a second port ...if you don't have a router and use dialup then connect the ethernet to teh PC or you can connect the ps3 to a laptop with the ethernet if the Laptop has internet( run network connections on the laptop as well)...then



Goto settings



Goto network settings



Goto network connection, select enable



Goto Internet connection settings just below internet connection-



Push yes when it says you may be disconnected



Select wired or wireless



For wireless use scan or enter manually



Follow on screen instructions.



Once that is set up return to main menu and go to network near the rightHow do i get my ps3 online?
you need a highspeed internet connection like DSL or Cable the cable goes from the PS3 to the Router or cable / DSL Modem
