Unfortunately system restore did come to mind, but also failed. As it transpires, the issue appears to have sorted itself out. After becoming frustrated with this card coupled with WiDi issues related to windows 8.1 and multiple monitors (can't add the wireless extender connected to my TV (a P2TV3000) as a 4th display), I purchased a $12 USB Bluetooth adapter from Amazon in an attempt to restore Bluetooth to my PC and planned to just leave Bluetooth disconnected. Upon plugging it in though and having it register in device manager no problem I was still unable to pair my phone or tablet to the PC as they would not detect from the PC or device end, likely due to some sort of conflict with the wireless adapter that I was still using for WiFi.
Defeated, I removed the USB adapter which I can hopefully use somewhere else and on a whim re-seated the card once more and re-connected the Bluetooth cable as I had it originally (pins reversed). Miraculously, when I re-booted the card registered this time with Device Manager and Bluetooth was restored (successfully able to re-pair my phone and tablet)!
The only other possible thing I can think of that might have caused a conflict was I had my infrared sensor enabled in BIOS which was not being used. Disabling this also removed the unknown device I was having trouble identifying in device manager. For reference my motherboard is an Asrock Z68 Extreme3 Gen3.
Now if I can just get the WiDi issue sorted, but that's for another forum which I know you're involved with. No disrespect and I know this isn't your fault, but in my opinion, Intel should really just stick to processors and leave wireless networking to more established brands like Cisco and Netgear, as this card has been nothing but a headache for what should be simple tasks. Thanks anyway for trying to support the community!
