Possible Causes

Weak Wi‑Fi signal at dock location, Incorrect Wi‑Fi password or unsupported band, Internal Wi‑Fi module fault, Antenna cable loose or damaged

How to Fix / Troubleshooting

Safety first: No internal high‑voltage risk, but avoid opening the robot unless experienced.

  • Check network: Ensure your router is on 2.4 GHz (if required by your Eureka model) and that the password is correct.
  • Improve signal: Move the dock closer to the router or use a Wi‑Fi extender.
  • Reset Wi‑Fi: Use the app or button combination to reset the robot's network settings and re‑pair it.
  • If E16 persists near the router: The internal Wi‑Fi Module / Antenna may be defective or disconnected. This typically requires opening the robot and reseating or replacing the Wi‑Fi board or main PCB.
