Thermostat frequently disconnects from Wi‑Fi and goes offline in the Bosch app.

Safety: No electrical work is needed.

• Check signal strength: Use your phone near the thermostat to check Wi‑Fi bars. If low, move the router closer or install a Wi‑Fi extender.
• Router settings: Disable aggressive power‑saving features and band steering that may push devices between 2.4 and 5 GHz. Ensure 2.4 GHz is enabled.
• Change channel: Log into your router and set a less congested 2.4 GHz channel (1, 6, or 11) to reduce interference.
• Update router firmware: Install the latest firmware from your router manufacturer.
• Re‑add network: Forget and re‑add the Wi‑Fi network on the thermostat via the Bosch app or device menu.
