Charger randomly disconnects from Wi‑Fi or cloud services; remote control via app is unreliable, but local charging works.

Safety first: Network issues do not usually affect electrical safety, but avoid unnecessary opening of the unit.

Steps to try:

• Improve Wi‑Fi signal: Move your router closer, add a Wi‑Fi extender, or use a wired Ethernet connection if supported.
• Check router settings: Ensure DHCP is enabled and that the router is not blocking the charger’s MAC address.
• Assign static IP (optional): For stability, assign a static IP to the charger in your router settings.
• Firmware update: Update both router and charger firmware to the latest versions.
• If still unstable: A technician may need to replace the Wi‑Fi module or antenna inside the charger.
