Audi wallbox’s Wi-Fi connection is unstable or frequently drops, causing remote control and monitoring issues.

Safety first: Network issues do not affect electrical safety directly, but avoid opening the unit with power on.

• Check signal strength: Use a smartphone near the charger to measure Wi-Fi signal. If weak, move the router closer or install a Wi-Fi extender.
• Change Wi-Fi channel: In your router settings, select a less congested channel to reduce interference.
• Update firmware: Ensure the charger firmware and communication module firmware are up to date via the Audi app.
• Inspect antenna connection: With power off, a technician can open the unit and verify that any internal Wi-Fi antenna cable is securely connected to the communication module.

If instability persists despite strong signal and updated firmware, the Wi-Fi module may need replacement.
