Robot vacuum does not respond to app commands, but cleans normally when started manually.

Safety first: Network troubleshooting does not require opening the robot.

• 1. Check robot Wi‑Fi status: On the robot or in the app, confirm it shows as connected to your home network.
• 2. Restart network: Power cycle your router and modem, then reboot the robot.
• 3. Update app: Ensure the LG ThinQ app is updated to the latest version.
• 4. Re-add device: Remove the robot from the app and go through the pairing process again.
• If the robot cannot stay online while other devices work fine, the internal Wi‑Fi module or antenna may be failing.
