Hi there!
I recently got a car stereo that has wifi capabilities so I added a Sierra Wireless AirCard 763S to the car to turn it into a permanant mobile hotspot. The car system can use internet access for navigation, traffic info and internet radio. My son can also connect to the network using his ipod or ipad on longer trips.
The only issue I've had is that the unit drops all devices when we go from an area with LTE coverage to one that has 4G. It requires a restart in order for devices to reconnect.
Tech support had me modify the profile so it stays on 4G to fix the problem. That does work but it seems like a less-than-ideal solution when I have LTE access 95% of the time but am forced to stay on 4G to have a reliable connection.
Is this really expected behaviour as tech support suggests?
