Thermostat frequently loses Wi‑Fi connection; app shows device offline intermittently

Safety: Network-only troubleshooting; no electrical work required.

• Step 1 – Check signal strength: Use a smartphone near the thermostat to check Wi‑Fi signal bars. If low, move the router closer or install a Wi‑Fi extender.
• Step 2 – Router reboot: Restart the router and modem. Ensure the router firmware is up to date.
• Step 3 – Change channel: Log into the router and change the 2.4 GHz channel to a less congested one (1, 6, or 11).
• Step 4 – Limit devices: Reduce the number of devices connected to the same network or enable QoS if available.
• Step 5 – Static IP (advanced): Assign a DHCP reservation or static IP to the thermostat to avoid IP conflicts.
