Google Nest Mini (2nd gen) — smart-home gadget keeps going offline

Why does my Google Nest Mini (2nd gen) smart device keeps going offline?

The short answer

"Something went wrong" when setting it up in a far room, or it drops out of a speaker group. On the WiFiXpert Compatibility Index the Google Nest Mini (2nd gen) scores 80/100, and its weakest check is "Works on a guest network" — which is exactly where this problem comes from. Casting from a guest network does not work.
