Hyundai charger cannot connect to the home Wi‑Fi network; app shows the charger as offline.

Safety first: Network troubleshooting does not require opening mains compartments.

• Signal strength: Use a smartphone near the charger to check Wi‑Fi bars. If low, move the router or add a Wi‑Fi extender.
• Reconfigure network: In the Hyundai app, forget and re‑add the charger, entering the correct SSID and password.
• Router settings: Disable MAC filtering or add the charger’s MAC address to the allowed list.
• 2.4 GHz vs 5 GHz: Ensure the charger is connecting to a supported band (often 2.4 GHz only).
• If still offline: The internal Wi‑Fi module or antenna may be defective and should be replaced.
