Look, if it's showing up like that in the Device Manager like you said, then the thing actually has to be working...

I mean, it might be functioning perfectly fine, you just haven't figured out how to actually talk to it yet...
Try hitting Start > Run, type in "fsquirt" and hit enter, then just mess around in there and see if you can send or receive something...
Once you've done that, check this out:

See if there's a Wi-Fi icon hanging around somewhere and set it to stay visible all the time, just to be safe.
Also, check the Control Panel under "Devices and Printers" to see if anything shows up there.

...and hey, you can also head over to the Network and Sharing Center in the Control Panel > Change adapter settings > right-click on the Wi-Fi connection > view Wi-Fi network connections and then try to
add a device—there should be a button right there that says
add a bluetooth device.
