We have had issues where the Wi-Fi hotspot would work for the first few hours but would not work when you restarted after fueling. Had several long conversations with AT&T and determined we needed the update as well. Very good tech @ Uconnect provided the 40.1 firmware version info and the info that the firmware status portion of the drive Uconnect website is non-functional for two years now.
Went to dealer to get the firmware update, and it wouldn’t load. They ordered an exchange radio that came with 40.1 installed. Wi-Fi still wouldn’t work so talked to an AT&T tech, who was less than helpful, and started to wait for more info. After a few days called AT&T again and talked to a very knowledgeable female tech. She said that since the radio was changed the IMEI number and ICCID numbers they had on file for my VIN would need to be updated. She said it would take 72 hours to become active.
Three days later we were on a trip and the Wi-Fi worked great.
The exchange radio came with a 4 digit pin as well. I’m wondering if this is the same pin required for FOB programming.
