I searched & couldn't find any information about this on the forum. The parking space underground at my apartment where the EVSE is installed is just barely too far away from my apartment to be able to access my wifi. This has never really matterd, but since the Model S uses wifi for software updates I am wondering about the impact. Will the software updates only download over wifi? Is there a way to make them download over LTE? The AT&T cellular signal in the parking garage is also very poor. My AT&T iPhone frequently switches to "no service" when I'm underground in the garage. So I'm not sure how well installing updates over LTE would work at home. I may have to install the updates when out somewhere and the car is parked for hours.
