Thermostat frequently disconnects from Wi‑Fi or Schneider Electric cloud app.

Safety: No electrical work is required.

Steps:

• Check Wi‑Fi signal strength on the thermostat (if displayed) or via the Schneider Electric app. If signal is low, move the router closer or install a Wi‑Fi extender.
• Ensure the thermostat is connected to a 2.4 GHz network if it does not support 5 GHz. Disable band steering or Smart Connect features that may confuse IoT devices.
• Update the thermostat firmware via the app or building management system to the latest version.
• Assign a fixed IP address (DHCP reservation) to the thermostat in your router to reduce connection drops.
• If other devices are stable and only the thermostat drops, the internal Wi‑Fi module may be degrading; replacement of the thermostat may be necessary.
