I don't know if this is going to be helpful, but I had started down the same road when I found your post. Thank you for this, great info!!! In my case, I had the same symptoms. I decided to see what the WiFi was even doing.
I started with a signal analyzer I had and realized, I was not putting out anywhere near the right amount of power. So I switched my power supply, it turns out my favorite dell USB C power pack is toast. It was at one point 40w now its putting out enough power to fire that led on the crab nice and bright and no more. I don't know if this will help you, but I hope it helps someone.
