Thermostat frequently disconnects from Wi‑Fi and drops offline in the Geo app, but local control still works.

Safety first: No high‑voltage work is required.

• Step 1 – Check signal strength: In the Geo app or thermostat menu, view Wi‑Fi signal strength. If low, move the router closer or install a Wi‑Fi extender between the router and thermostat.
• Step 2 – Use 2.4 GHz only: Ensure the thermostat is connected to a 2.4 GHz SSID. Disable band steering or create a dedicated 2.4 GHz network if necessary.
• Step 3 – Reduce interference: Keep the router away from microwaves, cordless phones, and thick metal objects. Change the Wi‑Fi channel to a less congested one (1, 6, or 11).
• Step 4 – Assign static IP: In your router settings, reserve a static IP address for the thermostat to prevent DHCP conflicts.
• Step 5 – Firmware update: Update both the router firmware and Geo thermostat firmware to the latest versions.
• Step 6 – Replace thermostat if module is unstable: If other devices are stable on Wi‑Fi and only the thermostat drops, the internal Wi‑Fi module may be failing. Replace the thermostat head unit.
