In short, you can't. Use corporal punishment for the child instead.

You *could* perhaps setup another router, using the same SSID as the
neighbors, in the room immediately adjacent to the child's room. Most game
consoles only go by the SSID name with the strongest signal. Turn on the
router and leave it connected to nothing. Granted, this may also cause some
headaches for the neighbor.

Personally I'm of the opinion it's better to use non-technology driven
solutions to parenting problems. But hey, feel free to be as lazy as you
like, someone's gotta raise the next generation of fry cooks, right?
