No idea ours is normally plugged into the router.

can you connect an Ethernet cord to it?

I don't have that ability.

i know that most commonly sony won't help you fix it but rather send you a new one, which even if they would do it with a ps3 (they may only be replacing ps4's now) you'd lose all yourshit unless you could back it up, but even that may screw up your dlc

That's the conclusion that I am coming to as well. I thought about buying flash drive with a decent memory size and seeing if buying a used one that is known to work on Wifi and transferring the data to that one. But the way things are going GT7 is rumored to be coming out on the PS4 next year. So it may be a waste of my money to do spend it on a possible obsolete set up only months ahead of the newest thing.
