Thermostat frequently disconnects from Wi‑Fi or Trane Home app

Note: This does not usually affect basic HVAC operation.

• Step 1 – Check signal strength: Use a smartphone at the thermostat location to verify Wi‑Fi strength. Aim for at least 2–3 bars.
• Step 2 – Move or upgrade router: Relocate the router closer to the thermostat or add a Wi‑Fi extender/mesh node.
• Step 3 – Update router firmware: Log into your router and install any available firmware updates.
• Step 4 – Change Wi‑Fi channel: Set the router to a less congested channel (1, 6, or 11 on 2.4 GHz).
• Step 5 – Reset thermostat network settings: Forget the network on the thermostat and reconnect with the correct password.
• Step 6 – If dropouts continue on a strong network: The thermostat’s Wi‑Fi module may be failing; replacement may be needed.
