Google Nest Audio — smart-home gadget keeps going offline

Why does my Google Nest Audio smart device keeps going offline?

The short answer

The cast button disappears from Spotify or YouTube even though the speaker answers you. On the WiFiXpert Compatibility Index the Google Nest Audio scores 81/100, and its weakest check is "Works on a guest network" — which is exactly where this problem comes from. You cannot cast to it from a phone on the guest network.
