Safety first: Network adjustments are low risk; avoid opening mains-powered devices.

Improve Wi‑Fi coverage: Move the Tydom gateway closer to the router or use a Wi‑Fi extender. Avoid placing it behind TVs or inside metal cabinets.
Reduce interference: Keep the gateway and thermostat away from microwave ovens, cordless phone bases, and thick reinforced walls.
Router reboot: Restart the router and gateway. Ensure the router firmware is up to date.
Fixed IP (advanced): Assign a reserved IP address to the Tydom gateway in the router settings to reduce DHCP issues.

If dropouts continue despite good signal strength, the gateway or thermostat RF module may be failing and should be evaluated by a professional.

Thermostat frequently loses connection to the Delta Dore Tydom gateway; app shows device offline intermittently.
