MacBook Air 2019 wifi disconnection with overheating

It's so annoying that whenever my MacBook gets overheated it comes with repetition of wifi connection and disconnection, which happens obviously when running heavy programs such as Zoom, FaceTime or even Google Chrome... Why does this happen...? What's the mechanism between overheating and wifi disconnection? Any fundamental solutions other than not overloading my Mac or putting limits on CPU?

Thanks in advance !

Hi,

Try to run Apple Diagnostics if it's caused by WiFi hardware related issue(CNW001, CNW003 to CNW007).
