Why Is My Smart Thermostat Not Connecting to Wi-Fi?

Most smart thermostats fail to join Wi‑Fi due to weak signal, wrong password, 5 GHz–only networks, or router security settings. Power issues (like a missing C‑wire) and recent router name changes also block pairing. Our Denver team installs, programs, and troubleshoots Wi‑Fi thermostats, and we offer $50 off thermostat services through 2025-12-31.

Quick checks:

• Verify 2.4 GHz SSID and password.
• Reboot router and thermostat.
• Ensure steady power/C‑wire.
• Forget and re‑add the network.
