Let me tell you a little story about a 2008 Chevy truck. Around 2018 we had daily interference with our satellite receivers. It was a ongoing problem and we couldn't find anything wrong. We changed out LNB's and even the receivers. Ran temporary cable replacements on the ground. Finally someone noticed out outdoor wifi was going down at the same time as our other problems. We fired of a spectrum analyzer hooked to a tuned 5ghz dipole and nothing out of the ordinary. The next morning our CEO was calling cause fox news went out in the middle of his daily indoctrination and he was getting calls from his assholes buddies he golfed with were not getting their fix of manufactured outrage. We go to the headend and sure enough its out and the spectrum analyzer was showing a massive signal wider than the analyzer could display at once.
We of course were dealing with the problem and didn't notice the twenty year old in one of our old trucks loading up what he needed to bury some drops that day. We also didn't notice as soon as he drove off that everything started working again. After a few minutes of getting our ass chewed when the CEO called and wanted to know what we did and we had done nothing, our operations guy called the kid in the chevy back for something unrelated. As soon as he drove up everything went tits up again and it dawned on us all it was that truck. We switched him to a different vehicle and parked that one. After replacing a number of parts the problem went away on the truck.
It doesn't matter if its the weather or if it exists in you corner of the world. It can be anything cratering your signal. I've seen old lighting ballast interfere and all manner of electrical appliances. I know you can't be convinced because it hasn't happened to you yet but wireless is a poor poor substitute for a hard link.
