The Nintendo Channel has pretty much been a bust for me. I don't have the patience to wait for the videos to download. I get 9 seconds of video than I wait up to a minute or more for another 9 seconds to download. That's no way to watch a video. Maybe the wireless link is weak/bad but everything else (Internet Channel, Wii Shop and all of my Tivos) seems to have no problem with the WiFi connection.
