No, not to charge. The Tesla Wall Connector delivers power to the car without an internet connection. Tesla says connecting it to your home Wi-Fi lets you control, schedule and see data from the unit in the Tesla app, and lets firmware updates install automatically. Many owners connect it for updates and data, but charging itself does not depend on Wi-Fi.
