What if my Wi-Fi network goes offline?
If my Wi-Fi network goes offline, will the thermostat still operate as programmed?

ANSWERS:

Yes, if the Nest goes offline, it will continue to function as usual. You will not be able to adjust settings with your phone or computer, but adjustments can be made manually on the Nest itself.
Yes, it will work.
Yes it will. Have had this happen to me. As long as there is power to the thermostat it will work but you will not be able to communicate with it.
