Before we go any further, we would like to inform you that Intel does not support integration which is when the original wireless adapter is replaced by a different one. This kind of procedure is meant to be done by the computer OEM, regarding laptops and for motherboards that come with the wireless card already integraded, the manufacturer of such motherboard must be consulted as they may have modified and customized the pre installed card to meet the requirements of their product.

It also worked for me on a NUC6i5SYH which was showing a code 43 in bluetooth radios in device manager with the latest Intel drivers for the NUC6i5SYH. Nothing I could do, including uninstalling Microsoft’s KB3161608/3172605 and installing the Intel BT patch, would result in removing the yellow exclamation mark against bluetooth in device manager, although the patch did result in changing the bluetooth entry from a generic adapter to an Intel entry but with the error code 10.
Are there any more recent wireless and bluetooth drivers that work for the NUC6i5SYH running Windows 7 Professional 64 bit?
Unfortunately, there is no driver updates in sight for this adapter as of this post. At the moment, we have no information if there will be any updates for Windows*7 expect for the ones that already exist in our donwload center as you can confirm here: Intel® PROSet/Wireless Software and Drivers for Windows 7* - Version: 19.1.0
The latest version of the wireless driver listed on the page Downloads for Intel® NUC Kit NUC6i5SYH Drivers & Software is 19.0.1 dated 6/30/2016. This works for wireless with the NUC6i5SYH, but the latest driver for bluetooth listed on that page version 19.00.1621 does not install properly. From your post of 29 December 2015 it appears that a combination of working PROSET wireless and bluetooth drivers is needed for bluetooth to install properly. Is there a bluetooth driver that works properly with the PROSET driver you list at Download Intel® PROSet/Wireless Software and Drivers for Windows 7* ?
My bluetooth is also not working on my 8260. WiFi is working fine, but I get the "Unknown USB Device (Device Descriptor Request Failed). Checking its properties, it shows error code 43. I'm using a Gigabyte GC-WB867D-I (rev. 4.2). win10 pro 64-bit.
I was going to try your solution but I am unable to completely uninstall the wifi drivers. I have uninstalled the pro/wireless drivers from the programs list. I have uninstalled from the device manager, however, there is no option (checkbox) to delete the driver itself. When I restart the PC or scan for hardware changes, the wifi gets reinstalled.
