I'm using an Intel Dual Band Wireless-AC 7260 Plus Bluetooth adapter and I have the latest bios and the latest drivers installed under Windows 8.1 64-bit, so everything is up to date.
The problem is with the bluetooth connection, because I have a bluetooth mouse and the pointer stops at random times for 5-10-20 seconds, so I tried to uninstall and reinstall the drivers, but nothing helps and this is really annoying.
I completely disabled 2.4GHz on my router, but the bluetooth problem is still there, and I even tried to disable the power management settings on the adapter, but nothing changed, so I really need a solution.
With an usb bluetooth adapter the mouse is working great and it's working great with my other computer too, but I don't want to use an usb adapter with the NUC, this is why I ordered the Wireless-AC 7260 adapter.
