Need help with ps3 internet hook up

you can go wireless, but personally wired is better. what router do you have? switch everything off, plug a ethernet cable from one of your ports on router to ps3 then then switch it all on. on ps3 go to settings - network settings - internet connection settings - then select easy - then whether you wanna do it wireless or wired (up to you) then let it do its thing, once its found all your settings you can test the connection.
Have you set up an account on your ps3 yet?
