Are you using this computer for gaming?
What exactly do you mean by noise and sound distortion regarding your WiFi traffic?
Nope, I am not. This laptop is not a gaming laptop. It's a business model from Lenovo.
The noise is a popping noise. And as for sound distortion, it sounds like the distortion you would get when you listen to music while using a CPU test software to exhaust your CPU cycles. And they only happen when there is something going on through wifi, e.g., loading a webpage, downloading a file, watching Netflix, etc.
