Solution

1. Preparation

Ensure the Tesla is parked in an area with a clear signal to the Wi-Fi router.
Make sure the vehicle's software is up to date to avoid any compatibility issues.

2. Reset Network Settings

In the Tesla, go to Controls > Safety & Security.
Select Power Off to turn off the vehicle.
Wait for at least 2 minutes before turning the vehicle back on.
After powering back on, navigate to Controls > Wi-Fi and search for available networks.

3. Update Wi-Fi Settings

Connect the Tesla to a mobile hotspot if available to verify internet connectivity.
If the home Wi-Fi is still not recognized, remove the existing network by selecting it and choosing Forget Network.
Re-enter the Wi-Fi settings and connect to the home network again by selecting the correct SSID and entering the password.

4. Router Configuration

Access the router settings by logging into the router's admin panel (usually through a web browser).
Check the frequency band; ensure the router is broadcasting on both 2.4GHz and 5GHz bands (if applicable).
Ensure MAC address filtering is disabled or add the Tesla's MAC address to the allowed list.

5. Factory Reset (if necessary)

If connectivity issues persist, consider performing a factory reset on the Tesla’s infotainment system by going to Controls > Service > Factory Reset. This will restore settings to default but will not erase personal data.
