Recently obtained a ZTE Velocity 2 mobile hotspot. My Model 3 refuses to connect. I've tried everything, including reboots of the car and the device, but it won't connect. In fact the car also produces this error: "Unable to obtain IP address. Please check DHCP server settings. Every other device I have connects -- my Model S, iPhone, ipads, and computers. Is Tesla wifi garbage or am I doing something wrong? Without a wifi connection downloading software updates are impossible. In fact, yesterday I spent over an hour trying to get any device to connect to the car's wifi, including my iPhone hotspotAll produced the same error. Finally my iPhone hotspot connected and the software update downloaded. But it took way longer than it should have.
