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.
We publish what breaks with each router and mesh system, and the setting that fixes it.
