The Bluetooth functionality was not affected in my Hades Canyon by the Windows update. So, please recheck if Bluetooth is not switched OFF and/or use the Troubleshooter to find the problem.
Leon's luck notwithstanding, other folks have reported this phenomena.
I suggest that you try a clean WLAN install. Here is proper process for performing a clean WLAN Install:
Hope this helps,
"I do not even have Bluetooth in devices. And I do not even have button to turn it off or on." If your O.S. is Windows 10, than you have Bluetooth button: Windows Settings Devices > Bluetooth & other devices (see the attached image )
You don't have the Bluetooth toggle, since probably the Bluetooth is disabled.
1. Enter BIOS - click on F2 during boot when you see the intel NUC logo.
2. In Advanced > Devices > Onboard Devices, check the Bluetooth.
3. Click on F10 followed by "Y" to save settings and exit.
4. Even better, you may set the BIOS settings to defaults - instead of enabling Bluetooth only (see para 2 above), while in BIOS, click on F9 followed by Y and then F10, confirmed by "Y".
