Thermostat frequently disconnects from Wi‑Fi; the app shows it offline several times per day.

Safety: Network-only troubleshooting.

• Check signal strength: Use a Wi‑Fi analyzer app near the thermostat to confirm signal is strong (better than −65 dBm).
• Change Wi‑Fi channel: Log into your router and select a less congested 2.4 GHz channel (1, 6, or 11).
• Disable router client isolation: Ensure features like AP isolation or aggressive idle timeouts are disabled.
• Relocate router or add mesh node: Move the router closer or add a mesh access point near the thermostat.

If dropouts persist with strong signal and stable router, the thermostat’s Wi‑Fi hardware may be failing and the Ngenic thermostat should be replaced.
