Solution

1. Preparation

Ensure the vehicle is in a safe location and powered on.
Have your Wi-Fi network name (SSID) and password ready.

2. Restart the Vehicle

Press and hold the two scroll wheels on the steering wheel simultaneously until the touchscreen goes blank.
Wait for the Tesla logo to appear before releasing the scroll wheels.
Allow the system to reboot completely.

3. Forget and Reconnect to Wi-Fi

On the touchscreen, go to 'Controls' > 'Wi-Fi'.
Select the current Wi-Fi network and choose the option to "Forget Network."
Wait a few moments and then select the network again.
Enter the Wi-Fi password and confirm the connection.

4. Update Vehicle Software

On the touchscreen, go to 'Controls' > 'Software'.
Check for any available updates and follow the prompts to download and install them.
Ensure the vehicle is connected to Wi-Fi during this process.

5. Router Settings Adjustment

Access your Wi-Fi router settings through a web browser.
Ensure that the router is broadcasting on both the 2.4GHz and 5GHz bands, as the Tesla may perform better on one of these frequencies.
Look for any MAC address filtering settings and ensure the Tesla's MAC address is allowed.
