Superb article, high on info, low on confusion! For my own home, I used to try to optimize the hell out of it (regularly switching channels, trying new routers etc.) Now I "installed" a TP-Link Deco M9 system. I have 250 Mbps coming in, and at the worst part of my house, my iPhone will still get 100 Mbps from that. That is more than enough even for streaming 4K. So I have now arrived at the "why bother tinkering with a good enough system" stage of WiFi, which is a huge relief.
