    I am a Model 3 reservation holder and will be living in a location where my car will be parked outside of the range of any wifi. Will I still be able to receive software updates via the built in LTE in the car? I am hoping that it will only take longer and still be able to receive the updates.

    Any info would be greatly appreciated.

    yes, wifi isn't required (at least on the current cars), but may give cars priority over the on-board cell signal (there's some mixed reports on this)

      The car downloads updates in the background by any internet connection it can get. It uses wifi if it has access to it, otherwise the built in LTE (or 3G for me).

      I have my car connected to Wifi at work (from the parking lot) and at home in the garage, but I've gotten new software update notices while it was sitting at an airport. (Note that as tempting as it may be, drive home first before installing that shiny new update, you'll thank me for that later).

          It is best to install updates on a 'quiet' network, like your home WiFi is at night after you go to bed. A busy network, like public networks can sometimes drop a bit or two because of all of the switching going on, other radio noise in the environment and low signal strength. This will not necessarily result in corrupted firmware because of file verification but may result in very long update times if several tries are needed to get it right.

            Of course... But, outside of visiting the service center directly and having them forced a released FW onto the car (at their discretion)...

            Tesla software updates just "magically appear" so, even if the file took a long time to download, you never know until it's ready to be installed (and all verification that it goes through is presumably complete.)

              Don't worry. The updates are downloaded in the background and stored for staging in the car over LTE, G3 or WIFI, whichever is available. Just remember that depending on the size of the update that is can take up to 2 hours to perform the update so your car is immobilized during that time. Best to schedule them overnight when you're sleeping.

              Since our car will live outside I installed one of these outdoor WIFI extenders on the house. It's powerful, I can get internet all the way down the street :)

                @TrevP perhaps you can lower your Internet costs by becoming your neighborhood ISP! ;)

                I just let our cars use the best available Internet for itself... Whether the wifi or the mobile connection...

                  Hmmm . . . using Ookla Speedtest, I find that LTE on my phone is up to 5 times faster than Wi-Fi in my house. Even with only "2 bars," it's 50% faster than Wi-Fi is at the same distance from the router as the car would be in the garage.

                  My Internet connection is 28Mbs but over Wi-Fi, either g or n, I measure only about 8-9Mbs. With 2 bars of LTE I get 14Mbs and with 5 bars, I've measured it up to 90Mbs, so I'm not positive that using LTE would result in "very long update times." It might be quite a bit faster, depending on location, but I don't think it would be slower.

                  Not that it matters in the end ;)
