Macbook pro 2019 constantly dropping wifi

I have seen this issue listed multiple times and never see a real answer.

Why is my MacBook Pro, which conveniently didn't do this when it was still under warranty, suddenly dropping wifi constantly?

This happens regardless of router, regardless of reseting router, computer fully up to date, regardless of distance from router. Computer is not overheating. Password for wifi is correct. Computer cannot and is not registered to try to connect to any other router in the area. When I mentioned this did not happen before, I want to clarify that I had the same router at that time, so the effectiveness and range of the router is not a contributing factor.

Please tell me there is a real answer for this problem.
