Troubleshooting Steps:

1. Check the Wi-Fi Settings:
The first step is to verify that the Wi-Fi settings on your Mercedes-Benz C4 Xentry Diagnostic Tool are correctly configured. Ensure that the Wi-Fi setting is enabled and that the tool is connected to the correct network. Double-check the Wi-Fi password, as any incorrect entry may hinder connectivity.

This step will remove any saved network configurations and allow you to set them up again from scratch. Refer to the user manual or manufacturer's website for specific instructions on how to reset the network settings.
