Tesla Vehicle Wireless Network Software Glitch (Initializing Loop)

This is a video of a wireless network card software glitch that was introduced in Tesla Firmware 17.11.3 (the first 8.1 update) and affects HW2 cars and possibly HW1 cars as well.

The symptom experienced is that once connecting to certain Wifi networks, the wireless network card resets and displays "Initializing" for a minute before it can see wireless networks again. This affects both the WiFi and Bluetooth connections. Once initialization finishes and it connects to the WiFi network again, it stays connected for 10 or so seconds before it happens all over again. 10 seconds of actual connectivity result in a minute and a half of being disconnected in an endless loop.

The problem would seem to be that the WiFi card is getting a response back from another device on the network (in response to a broadcast packet) that is causing the driver to crash. If this is the case, it's something that will need to be fixed by a firmware update from Tesla.

There is a workaround that can be done in the meantime, and that is to connect the Tesla to a wireless network that it doesn't have to share with other network devices. This can be done by turning on Network Isolation (a feature that blocks devices on a network from talking to one another) which may or may not be desirable. Another option is to put the Tesla on a separate SSID (which works with multi band routers/access points) or Wireless Guest Network (an isolated network on a separate SSID for visitors). I'll post back with results if this works.

**** UPDATE ****

After a lot of testing I've been able to get the car to stay connected if I place it on an isolated network segment where it can't talk to any other devices, only the internet. That appears to be a valid workaround until this bug is fixed.
