Why Is My Smart Thermostat Not Connecting to Wi-Fi?
Most smart thermostat Wi‑Fi issues come from signal or setup problems. Typical causes are weak signal at the thermostat, incorrect password, recent router/SSID changes, or a 2.4 GHz vs 5 GHz mismatch. Power or wiring can also interrupt pairing. Appleton Campbell installs and replaces thermostats and diagnoses smart controls and zoning in Warrenton and nearby areas.
- Restart the thermostat and router.
- Use the 2.4 GHz band if required.
- Re-enter the exact Wi‑Fi name and password.
- Improve signal or add an extender; then retry pairing.
