Possible Causes

Weak Wi‑Fi signal at charger, Interference from neighboring networks, Faulty Wi‑Fi antenna or module, Router power‑saving or band‑steering issues

How to Fix / Troubleshooting

Safety first: Network changes are electrically safe.

  • Improve signal: Move the router closer, add a Wi‑Fi extender, or use a wired Ethernet connection if the VW wallbox supports it.
  • Lock to 2.4 GHz: Configure the router to provide a stable 2.4 GHz SSID; some EVSEs have issues with 5 GHz or band steering.
  • Assign static IP: Reserve an IP address for the VW wallbox in the router to reduce dropouts.

If instability continues, the internal Wi‑Fi module or antenna may be defective and require replacement.
