So you are asking if there is a product that will run a ethernet cable without running a ethernet cable? If so, no.
Do you mean how do you get your PS4 online without running a cable? If so, why not wireless? The PS4 has a built in wireless adapter. Do you have a wireless router? If so, what model number? Powerline might work well, but then you have to buy stuff, and depending on which adapters you get, how your house is wired, and what wireless router you have, it might not even work better.
