Solution

1. Preparation

Ensure the vehicle is parked in a location with a strong Wi-Fi signal.
Have access to the Wi-Fi network's name (SSID) and password.

2. Restart the Infotainment System

Sub-steps:
1. Press and hold the two scroll wheels on the steering wheel simultaneously.

Sub-steps:
1. Access your router’s settings through a web browser by entering the router's IP address.
2. Ensure the Wi-Fi is enabled and broadcasting the SSID.
3. Check that MAC address filtering is not blocking the Tesla; you may need to add the vehicle's MAC address to the allowed list.
4. If using dual-band, ensure the 2.4 GHz band is enabled and try connecting to that band.

5. Factory Reset (if necessary)

Sub-steps:
1. Navigate to 'Controls' > 'Service' > 'Factory Reset'.
