Wi-Fi is available as a data connection method and is often faster than cellular data networks.
Connecting to Wi-Fi is especially useful in areas with limited or no cellular connectivity.
To ensure fast, reliable delivery of software and map updates, Tesla recommends leaving your vehicle connected to a Wi-Fi network whenever possible (for example, if parked in your garage overnight).
To connect to a Wi-Fi network:
Model 3 will start scanning and display the detected Wi-Fi networks that are within range.
You can also connect to a hidden network that isn't shown on the list of scanned networks.
Just touch Wi-Fi Settings, enter the name of the network in the resulting dialog box, select the security setting, then touch Add Network.
Note: If more than one previously connected network is within range, Model 3 connects to the one most recently used.
Note: You can also use a mobile hotspot or your phone's Internet connection via Wi-Fi tethering (subject to fees and restrictions of your mobile carrier).
Note: At Tesla Service Centers, Model 3 automatically connects to the Tesla Service Wi-Fi network.
