Mercedes-Benz Unstable Network / Connectivity Issue

Wallbox frequently disconnects from the Mercedes-Benz app or loses remote connectivity, but local charging works.

Possible Causes

Weak Wi-Fi signal, Interference from other wireless devices, Faulty Wi-Fi module, Router DHCP or firewall misconfiguration

Note: Connectivity issues do not usually affect basic charging.

Improve Wi-Fi coverage: Move the router closer, adjust antennas, or install a Wi-Fi extender near the wallbox.
Use 2.4 GHz band: Ensure the wallbox is connected to a 2.4 GHz network if it does not support 5 GHz.
Assign static IP: Configure a DHCP reservation or static IP for the wallbox to reduce connection drops.
Firmware update: Update both router and wallbox firmware to the latest versions.
