The range stretches round the whole world through Wifi
Just to let you know, it is not exactly worldwide. For wi-fi games, you can only play people in your country. But back to the real question, I'm not too sure. But whoever said that the sensor bar does not matter, you are wrong. One time, my sensor bar fell down, and i didn't notice it, and I couldnt do anything on the wii.
