Possible Causes
Faulty internal Wi-Fi module or Ethernet interface, Damaged antenna or antenna cable, Incorrect network credentials or router settings, Firmware bug affecting connectivity.
How to Fix / Troubleshooting
Safety warning: Network issues do not usually affect electrical safety, but always isolate power before opening the unit.
- 1. Check router and internet: Confirm your home network is working and that other devices can connect.
- 2. Re-enter Wi-Fi credentials: Using the Land Rover charger app, forget the existing network and reconfigure Wi-Fi settings. Ensure the correct SSID and password are used.
- 3. Move router or improve signal: If the charger is far from the router, consider moving the router closer or using a Wi-Fi extender. Avoid metal objects blocking the signal near the charger.
- 4. Inspect antenna (advanced): With power OFF, open the charger and check that the Wi-Fi antenna cable is securely connected to the communication module and that the antenna is not damaged.
- 5. Update firmware: If possible via USB or local connection, update the charger firmware to the latest version provided by Land Rover.
- 6. If E12 persists: The communication module may need replacement. Contact Land Rover support or a service partner for module replacement.
