Charger shows E12; Wi‑Fi or network icon may be flashing; charging may still work but with limited features

Safety first: Network issues are low‑voltage, but do not open the charger unless necessary. Charging may still be safe if only connectivity is affected.

• Check Wi‑Fi signal: Use a phone near the EVgo charger to verify signal strength. If weak, move the router or add a Wi‑Fi extender.
• Reconfigure network: Using the EVgo app or local web interface (if available), re‑enter Wi‑Fi SSID and password. Ensure the network is 2.4 GHz if the charger does not support 5 GHz.
• Router settings: Confirm that the router is not blocking outbound connections from the charger’s MAC address. Disable overly strict firewalls or parental controls for the charger.
• Reboot charger and router: Power‑cycle both devices and check if E12 clears.

If E12 persists and other devices work fine on the same network, the EVgo Wi‑Fi module or communication board may be defective and require replacement.
