I've encountered what appears to be a bug in firmware versions 17.11.3 and up. When attaching to certain WiFi networks, the wireless NIC appears to crash resulting in it going into an "Initializing" state. It happens usually within about 10 seconds of connecting to a network. Best guess is that the response it's getting to its broadcast traffic from other devices once it connects to the network is causing the crash. I spoke with another owner who has both an S and an X at the Denver service center who has observed the same behavior. He said that a workaround might be to isolate the Tesla from other network devices (i.e. using a guest network or Network Isolation).
While I wasn't able to get my Tesla to connect to a guest wireless network at all (not sure why, would fail with no error) I was able to connect it to a second router running a double NAT off my main router. That fixed the problem, so at least there's a workaround.
I have two routers. The Asus RT-AC5300 and a Netgear R6300. The Asus runs as my primary for all of my devices and is my DHCP server. Here are the various things I tried:
- Connect Tesla to Asus primary 2.4ghz SSID: Connects but resets constantly (symptom)
- Connect Tesla to Netgear acting as bridge for Asus primary 2.4ghz SSID: Connects but resets constantly (symptom)
- Connect Tesla to Asus Guest SSID isolated from LAN: Fails to connect with no error.
- Connect Tesla to Netgear in bridge mode for Asus Guest SSID isolated from LAN: Fails to connect with no error.
- Connect Tesla to Netgear while it's not connected to the internet either as a bridge or over LAN cable (as an experiment): Fails to connect kicking back to password prompt (Tesla won't apparently stay connected to a WiFi network with no internet access).
- Connect to Netgear running as a "downstream" router from the Asus (double NAT, meaning that the Asus is plugged into my Comcast gateway through i's Internet port and my Netgear is plugged into my Asus through its Internet port, creating an isolated WiFi network with no other devices on it): Works.

I suspect that more people might be experiencing this issue but haven't noticed.
