Smart thermostat won't connect to WiFi? Here's Who to Call
A smart thermostat that cannot maintain a WiFi connection loses remote control, scheduled programming, and energy-saving features such as geofencing and usage reports. The root cause may be weak signal strength near the thermostat, an incompatible router band or security protocol, outdated thermostat firmware, or a power issue on the C-wire. A smart-home installer diagnoses the connectivity fault, updates firmware, adjusts router settings or installs a mesh node for better coverage, and verifies the thermostat stays online through multiple connection cycles.
