I bought a Wii a few years back and never had a problem. I sat it by my tv, on a dresser in front my bed. The reason being so I could chill on my bed and play. Ok so, never any problems.
Well, my dog pulled my censor bar and Wii remote off the dresser and ate 'em
I bought a new censor bar identical to the one you get with the Wii (Not wireless) and a Wii motion plus remote. And now for some reason, I have to sit right up on the tv, if not two, three feet away for the cursor to show up. Where as before, I could sit like, 10 feet away. If I back up even 6 inches it starts jumping all over the place, back up to where I use to sit and it completely disappears. What gives!!
