Did this update break Youtube playback in the browser? I was just trying to throw a video up on my TV and there's just an empty box where the Youtube player should be.
This is NOT the same as WiiConnect24. The Wii was connected 24/7 and constantly pinging Nintendo's servers with that. With the Wii U, this will only check the server every once in a while. It's very different and won't put stress on the Wii U's wireless card.
