Nest thermostat shows N1 and cannot find any Wi‑Fi networks

Note: N1 affects remote access but not basic HVAC control.

• Check network settings: On the Nest, go to Settings > Network and ensure Wi‑Fi is turned on.
• Reboot Nest: Press and hold the ring for 10 seconds to restart the thermostat.
• Reduce interference: Move cordless phone bases, baby monitors, or microwave ovens away from the thermostat and router if they are very close.
• Test with another network: If possible, create a mobile hotspot and see if the Nest can detect it. If not, the Wi‑Fi hardware may be faulty.

Persistent N1 usually indicates a failed Wi‑Fi module; the Nest display may need replacement.
