Has anyone else noticed that if they have wifi enabled, if the car detects and connects to a wifi source that it will NOT use 3G for any reason. This becomes a problem if the wifi source itself is having connection issues or if the wifi signal isnt' strong enough to work with any reasonable speed. If either of those scenarios happen, the car becomes stranded connectivity wise. On iphones, there is a wifi boost feature where it prefers to use wifi but if the signal is weak or connectivity is slow, it will assist it by using 3G/LTE. The brainless implementation of the wifi in the Model S is a joke.
