Charger shows E13 and cannot connect to the Hyundai EV charging app or network.

Safety first: Network troubleshooting can be done with power ON; do not open live compartments.

• Check router and signal: Ensure the home router is powered and within range. Test Wi‑Fi signal strength near the charger with a phone.
• Reboot devices: Power cycle the router and then the Hyundai charger (via breaker) to clear temporary network issues.
• Verify credentials: In the Hyundai app, confirm the correct SSID and password are configured.
• Ethernet models: If using Ethernet, verify the cable is fully inserted and test it with another device.
• If E13 remains and other devices work fine: The Wi‑Fi/Ethernet module or antenna inside the charger may be defective and should be replaced by a technician.
