Unstable Wireless Connectivity
VW wallbox frequently loses Wi-Fi connection; app shows charger offline intermittently, though local charging continues.

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.
