How much is the Wi-Fi transferring for you? I have been measuring my Model X + Wi-Fi for around ten days now and witnessing steady but small transfer rates: Receive: 3.1 MBytes/day Send: 0.7 MBytes/day The car is parked at the Wi-Fi for most of the day and night. As mentioned, Tesla talks of music service caching (Future in-car services and music caching through Wi-Fi?), but obviously not at these rates. I don't use the online services in the car much, nor has data sharing been on during this time, so that certainly explains some of the smallness of the numbers. Curiously I am also not getting any software updates (as has happened before when using the Wi-Fi), so no 17.17.4 for me. I will probably give up on the WI-Fi, since Wi-Fi has hurt more than it has helped here. I do check the mobile app perhaps 0-2 times a day, if it is not turned off for some reason. I have also turned off energy saving etc., but they do not seem to have any effect on the transfer rates.
