The charger's Wi-Fi signal is weak or frequently disconnects, causing unreliable app control.

Safety first: Network issues do not affect electrical safety.

• Check signal strength: Use your phone near the charger to see Wi-Fi signal bars. If the signal is weak, move the router closer or add a Wi-Fi extender.
• Change Wi-Fi channel: Log into your router and select a less congested channel (e.g., 1, 6, or 11 on 2.4 GHz).
• Reposition router/charger: Avoid placing the router behind metal appliances or in a basement if the charger is outside.
• Technician step: If the signal is strong but the charger still disconnects, a technician can inspect and, if needed, replace the Wi-Fi antenna or communication module.
