Possible Causes

Defective Wi‑Fi module on Andersen communication board, Antenna cable disconnected inside enclosure, Corrupted network configuration in firmware, Excessive RF interference at installation site

How to Fix / Troubleshooting

Safety first: Network faults do not usually affect electrical safety, but do not open the unit while live.

User steps:

  • Reboot your home router and the Andersen charger (power cycle at consumer unit).
  • In the Andersen app, forget the charger and re‑add it following the pairing instructions.
  • Move Wi‑Fi access point closer or add a Wi‑Fi extender if signal is weak at the charger location.
  • If available, switch the charger to a 2.4 GHz SSID (many IoT devices prefer 2.4 GHz).

If E11 persists and Wi‑Fi remains unavailable:

  • A technician may need to open the unit (power isolated) and check the Wi‑Fi antenna connection to the communication module.
  • If the antenna and cabling are intact, replace the communication/Wi‑Fi module.
