Google Nest speaker & display — smart-home gadget keeps going offline

Why does my Google Nest speaker & display smart device keeps going offline?

The short answer

The cast button disappears, or the speaker answers but won't play from your phone. On the WiFiXpert Compatibility Index the Google Nest speaker & display scores 80/100, and its weakest check is "Works on a guest network" — which is exactly where this problem comes from. Your phone can't cast to it across a guest network.
