Wi-Fi connection is unstable or the charger frequently drops offline from the app.

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

• Signal strength: Use a smartphone near the charger to check Wi-Fi signal. If weak, move the router closer or add a Wi-Fi extender.
• Change channel: Adjust router Wi-Fi channel to avoid interference from neighbors.
• Firmware update: When connected, update the charger firmware via the app to improve network stability.

If connectivity remains poor despite strong signal, the internal Wi-Fi module may be failing and require replacement.
