Running Ubuntu 16.10 from a LiveUSB. Bluetooth adapter does not work. Even if I try Danilo Silva's suggestion of toggling Wi-Fi on/off using Fn keys. In my case, it should be Fn + F3. Actually, that key shortcut does not work for me. Pressing Fn + F3 if Wi-Fi is connected does not disable it, and vice versa.

Not sure if that matters, but Additional drivers suggested me installing intel-microcode (http://packages.ubuntu.com/intel-microcode). I installed it without effect.
