2021 Buick Enclave no wifi

Yep but Onstar can’t fix it🤬

My guess then that it's on the Buick/GMC side of things. On my Suburu, they had to replace the entire entertainment console as it is one integrated unit. That's why it took most of a day to replace/test. Of course this was last year, long before the 3G/4G shutdown.

@Perq  Life is all about marketing in one form or another. What AT&T does is not unique to AT&T. All providers and companies do it all of the time with their products.

I’m not sure what that has to do with my problem

OnStar relies on CDMA mobile to communicate with your car, which is cellular. AT&T's 4G network, prior to Feb. 2022, was actually 3G as I mentioned above. GSM and CDMA are part of the 3G spectrum. If OnStar is now using true LTE because most providers have, or will be dropping 3G very soon, then your Buick's Nav system needs to be upgraded to work.

Can you use any of the OnStar features at all? OnStar features work fine in the Suburu but I use BT to connect my iPhone to the car's NavSystem for any number of things. My car always connects to my home WiFi system when it gets within range.

Everything works except for WiFi.  Thank you for taking the time to explain all that to me

@OttoPylot I don’t know if that’s true or not but the specifications I found for a 2021 Enclave says the mobile internet is 4G LTE, not CDMA. Besides that, ATT’s connected car is definitely not CDMA. 

@jbean618 When you say only WiFi doesn’t work, do you mean devices can’t connect to the vehicle WiFi or do you mean they can connect, they just don’t get internet?

They won’t connect. My phone finds the network in my car but the car doesn’t have the network. When I try adding the network it cannot be found

If there’s a way to post pictures I can show you what I’m talking about

@sandblaster  The info I found for OnStar says it uses the CDMA network but maybe that info was old.
