Robot vacuum reports E11 and cannot connect to Wi‑Fi or the app; sometimes labeled as a communication or network error.

Safety first: Ensure the robot is on the dock with sufficient battery.

• Check Wi‑Fi network: Confirm your router is broadcasting a 2.4 GHz network (most Neabot robots do not support 5 GHz only). Ensure the password is correct.
• Move dock closer: Temporarily move the dock closer to the router to improve signal strength.
• Reset Wi‑Fi on robot: Follow the user manual to enter Wi‑Fi pairing mode (usually by holding a specific button until a voice prompt). Re-add the robot in the Neabot app.
• Restart router and robot: Power cycle your router and turn the robot off and back on.
• Firmware update: If connection is intermittent, update the robot firmware via the app when possible.

Warning: Do not attempt to open the robot to access the Wi‑Fi antenna unless you are experienced; internal antennas are fragile and can be easily damaged.
