Why Is My Smart Thermostat Not Connecting to Wi-Fi?
Most smart thermostats fail to join Wi‑Fi due to weak signal at the wall, wrong network/password, 5 GHz–only routers (many thermostats need 2.4 GHz), router security/settings conflicts, or low thermostat power. Our trained techs install and integrate smart thermostats and can diagnose connection issues in Roanoke, Cave Spring, and nearby areas.
Quick checks:
- Confirm 2.4 GHz SSID and correct password.
- Reboot router and thermostat.
- Move router or add a Wi‑Fi extender.
- Disable VPN/guest isolation; update router firmware.
- Verify C‑wire/power at the thermostat.
