Thermostat Wi‑Fi connection drops frequently or cannot stay connected to the home network

Safety: No HVAC electrical work is required.

• Signal strength: Use a smartphone at the thermostat location to check Wi‑Fi signal strength. If low, move the router closer or install a Wi‑Fi extender.
• Router settings: Ensure the router is broadcasting a 2.4 GHz network with WPA2 security, which is commonly supported by smart thermostats. Avoid using hidden SSIDs or unusual characters in the network name.
• Static IP / DHCP: If your network is complex, ensure the thermostat is allowed to obtain an IP address via DHCP and is not blocked by MAC filtering.
• Firmware updates: Update your router firmware and, if possible, the thermostat firmware.
• Thermostat hardware: If other devices work fine on Wi‑Fi and the thermostat alone drops frequently, its Wi‑Fi module may be failing. Replace the thermostat.
