Wi-Fi chip / radio

Source-linkedVerify source — Reddit post

Nest Learning Thermostat 3rd gen (Backplate-5.3 hardware) lost Wi-Fi connectivity entirely. Owner suspects repeated power cycles from a faulty zone valve cooked the Wi-Fi chip and notes this may already be a prior replacement for the same failure, leaving only local non-Wi-Fi programming options.
