An idiot actually doing this would make me smile knowing they spent more money than it cost to get a cable just to make a wifi scarlet letter disappear, while effectively making their network even worse in the process.
Sucker, I'm already doing this! Time to buy this game!
(I just repurposed my old Netgear Nighthawk router to a bridge because it's a fuckload better than the PS4's built in wifi, and I live with my landlady who will DEFINITELY not be cool with me snaking an ethernet cable from my bedroom, past 2 other bedrooms, down the stairs, past the dining room, and into the router behind the TV. OTOH I don't play fighting games so you don't have to worry about my wifi ass blowing up)
