Now that is more concise! Now we know, you did have a measurable decrease in signal.The only variable that I know of that has changed recently is that two 5G cellphone networks have gone live on (3.3GHz-3.8GHz range), which I assume do not interfere.
So then is it possible but for what I quoted you; I wouldn't write the 5G down at all, since even if not the same frequency its strong signal could interfere with your WiFi. I am no expert on the matter, but it is my opinion...
