I received Mi Box today, and right after initiate process it automatically restart (without questions) and install update. WTF? So I don't know is it problem in new update or not.

PROBLEM: After ≈5-10 min WiFi and BT stop working at all. Luckily I enabled CEC control. WiFi toggle button is off and can't be changed (not disableb but return back). Factory reset not resolve the problem. So I switch to WiFi 2GHz and looks like it is sollution. (I try 5GHz on Apple Time Capsule and on Mikrotik)

​

And KP related to problem, I think:
