I have very little wifi signal in the garage because of the distance, it's currently very difficult for me to stretch the router any closer to the car without getting under the house and moving the router to some awkward location. I do have a sort of older Apple Airport Extreme but it doesn't do all that well with AT&T when I use it as a wifi extender, possibly because it gets N/V but not G (again, I'm probably not describing this correctly), but I know it's one less than I currently can get through my router..Do you not have a good wifi signal? If the car can set up the VPN (it can login to the mothership), it should be fine. And wifi should be better than LTE. How strong does your wifi look on the MCU’s wifi signal indicator?
Charging shouldn’t be relevant. I have mine changing all the time as needed. Used to have an Apple AirPort Extreme for the whole house,’had a good signal in the garage, now have two Netgear Orbi’s to have a satellite closer and also to have the car on a guest network.
If any of you have tips, please let me know. I thought about logging in directly to the router (sorry if I'm describing this wrong) and then fix the IP address of the airport so it doesn't get randomly assigned addresses, and then perhaps creating a guest network from the wifi, would this work?
