Solution

1. Preparation

Ensure the vehicle is parked in a safe location.
Confirm that the Wi-Fi router is functional and within range.
Gather necessary tools for potential hardware inspection (e.g., screwdriver, multimeter).

2. Reset Network Settings

Go to the vehicle's touchscreen, navigate to "Settings," then select "Wi-Fi."
Choose "Forget Network" for the current Wi-Fi connection.
Reboot the vehicle’s infotainment system as described in the diagnostic steps.

3. Update Software

Check for software updates by going to "Software" on the touchscreen.
If an update is available, ensure the vehicle is connected to Wi-Fi and follow on-screen prompts to install the update.

4. Router Configuration

Access the router's settings via a web browser (usually 192.168.1.1 or similar).
Ensure that the firmware is up-to-date; if not, update it.
Adjust settings such as channel frequency (2.4 GHz or 5 GHz) to see if one works better for the Tesla.

5. Hardware Inspection (if necessary)

If the issue persists, inspect the vehicle's Wi-Fi antenna, which may require removing trim to access.
Use a multimeter to check for continuity in the antenna wiring.
Replace the antenna if any faults are detected.
