Hi,
If you are connecting manually, then you will need to remove the device and repeat the whole connecting process again.
However, if you are using Smoothboard, SmoothConnect will help you connect the Wiimotes. You will just need to press the 1+2 buttons with SmoothConnect is searching for the Wiimotes. Once connected, the Smoothboard software will be launched automatically.
