I changed this to DHCPS-dynamic but it looks not working. So I go ahead connect another standalone router with this combo and turn the Wi-Fi from ATT combo off. So the car joined the Wi-Fi from the standalone Router with no more error.
ATT gave me a modem/router combo device. Its default set to allow fixed DHCPS-fixed IP passthrough which needs to be changed to allow DHCPS-dynamic. Tesla is not compatible with fixed IP so it keeps searching for Dynamic IP. While you can change this setting within ATT combo but lots of folks...
I had the same problem.
It looks ATT combo has some problems, I connected another router with the combo, and turn off the combo wifi. The car finally works with the wifi with no error.
