Ever since I got my WiiU I've been experiencing interference when playing Wii games. Button presses get ignored occasionally and holding down a button will sometimes release in-game even though I haven't let go. I know my controllers arent broken, because this happens with all 5 of my Wii Remotes, both of my Nunchucks, and my Classic Controller. This makes it impossible to play games that require me to hold down a button or direction for more than a single frame. I've unplugged every other electronic in my house to see if it would help, but nothing changed.
My question is this: Is there something I can get that will let me plug the Classic Controller directly into the WiiU so that it sends the signals directly through the wire to the console instead of to the Wii Remote to send wirelessly? It is extremely frustrating not being able to play games properly. This is probably a silly question but I'm really getting desperate here.
If not, is there an extention cable I can get for the Classic Controller so I can just place the Wii Remote directly on top of the console? If there is nothing between them but the plastic of the controller and console, it might remove any interference problems.
