the problem is if the teammates/opponents also buy that $10 accessory ...

if not you might have a good connection, but it doesnt really matter if you opponents lags in front of you or if you play games like street fighter and your inputs are messed up ...

Contrary to what some people here think wi-fi works and Wii U has the best protocol available! You can play games lagless with it and doesn't need a 10 dollar accessory for most cases - if your connection sucks it'll suck with or without it.

Otherwise people wouldn't be playing Vita/3DS or watching HD Movies on iPad.
