You need to remove what I believe is a defective RealTek WiFi card and replace it with an Intel AX200NGW WiFi. I did that and have never experienced another WiFi issue. I never used Bluetooth so I don’t know whether my solution solved the problem. Lenovo would never own up to the defective part so I just purchased the part myself and installed it. Although it might appear to be that the wires from the WiFi antenna have been compromised, I assure you that is not the problem.
