Solution

1. Preparation

Ensure the vehicle is in park and the ignition is off.
Have the Wi-Fi network name (SSID) and password ready.

2. Restart the Vehicle

Press and hold both scroll wheels on the steering wheel until the touchscreen turns off and the Tesla logo appears.
Wait for the system to reboot completely (approximately 1-2 minutes).

3. Update Software

Navigate to 'Controls' > 'Software' on the touchscreen.
Check for any available software updates and install them if necessary. This may require a Wi-Fi connection temporarily.

4. Reconnect to Wi-Fi

Go to 'Controls' > 'Wi-Fi'.
Select the desired Wi-Fi network from the list.
Enter the correct password and confirm the connection.
Ensure the Wi-Fi icon appears in the status bar indicating a successful connection.

5. Check Network Configuration

Access your Wi-Fi router settings via a web browser.
Ensure that the router is not using MAC filtering that may prevent the Tesla from connecting.
Check for any updates or settings that may improve connectivity (e.g., changing the Wi-Fi channel, ensuring 2.4 GHz band is enabled, as some vehicles may not connect to 5 GHz networks).
