I've recently revived my old GA-X79-UD5 and it mostly works fine with Windows 10 64bit, except the wireless interfaces.
The wireless extension board had been detected as Qualcomm Atheros AR1111 WB-EG by Windows 10 which seems to be correct. Wi-fi seems to be working ok-ish, there are so hiccups every now and then, but Bluetooth is not available at all.

Tried installing Bluetooth drivers for Windows 8, that are provided on the support page but it doesn't seem to help.

Is there any way to make Bluetooth work on Windows 10 at all for GA-X79-UD5 or it's too old and I should just abandon the idea?
