Wii remote (motion plus inside) won't stay connected for more than a few seconds

[SK91]

I have a Wii motion plus inside Wii remote (though oddly enough it doesn't have the TR at the end.) It works perfectly fine for a few seconds using the"Passthrough a Bluetooth adapter" option until the wii remote disconnects after about 15-20 seconds. I've tried a fresh pair of batteries and I can tell you that's not the problem either.

I can't find out any specifics of what kind of Bluetooth adapter I have either, it just shows up as "Intel® Wireless Bluetooth®".
