Charger’s Wi-Fi or app connection is unreliable; charging may still work manually.

Safety first: Network troubleshooting is low electrical risk, but still avoid opening the unit while powered.

• Check signal strength: Use a smartphone at the charger location to verify Wi-Fi signal quality. If weak, move the router or add a Wi-Fi extender.
• Change Wi-Fi channel: In your router settings, select a less congested channel to reduce interference.
• Update firmware: Use the Zencar app or web interface to check for and install firmware updates that may improve connectivity.
• Inspect antenna: If accessible and with power OFF, ensure the Wi-Fi antenna cable is securely connected to the Wi-Fi/communication module and not pinched.
• If instability persists: Replace the Wi-Fi/communication module per Zencar instructions.
