Unlike Sony PlayStation 3 and Xbox 360 controllers, which use Bluetooth technology, the Nintendo Wii runs off of batteries and must stay in direct line of sight of the motion sensor equipment. Because of this, if you want to connect your Wiimote controller to a computer system, you do not need to use the Bluetooth features on the computer.
Connect the Nintendo to PC adaptor into a USB port on your computer.
Insert the driver installation CD into the computer's disc drive, and wait for the installation wizard to load onto your screen.
Accept the end-user agreement, and follow the prompts to install the driver onto the computer.
Plug the USB data cable into the USB port on the bottom of the Wii controller. Connect the opposite end of the cable into the USB port on the adaptor. The computer will momentarily state that it has detected the new controller.
