wifi

I have been having this same or similar issue recently as well. It was noticed after the dealership did a software update to the MyLink / radio software because the entire radio/screen would reboot if you changed the volume and sometimes even if you didn't. I can see the SSID that I created and am able to connect to it however my phone appears to not stay connected and it does not automatically reconnect if you shut the vehicle off. Is this a hardware issue within the vehicle or is a software/firmware issue within the vehicle hardware or is it something else. I would love to know so that I can get it resolved as well. I have reached out directly to OnStar they claimed everything appears from their end. Let me know.

Finally I found others with this issue. This has been happening to my 2020 Traverse for the past year.

They've reset the wifi many times by onstar. Dealership has replaced the radio, checked the Ethernet cable but it still can't be fixed.

They can't even replicate it. I have video of this and have shown the dealer so they know it exists. In the end, I was basically told it's unfixable.

Be nice this could be figured out.

SAME issue...MY21 Silverado 1500. Most of my wifi issues with remote startbare at home, I assume, where I don't have very much 4G signal. In town remote start/wifi issues are rare. I have to shut the truck off and open the door for about 60 seconds for the truck to reset itself. Then I start the truck with pushbutton and everything works fine. 

I have been having the same issue for over a year and a half and have recently left my vehicle with the GMC dealer for over a week while I was out of town. Nothing found and nothing fixed. Sounds like a software issue that needs fixing. The question is, what is being done to address this KNOWN problem. 

Same here with my 2020 Buick Encore. Been that way almost since it was new, and I always thought it was an OnStar issue. I pay yearly in advance for both Wi-Fi and the remote capabilities for my phone, both currently expire a year and 1 month from now. But as usual, when I remote start I have to turn my car off and recycle it for like 5 minutes and then start it normally for the Wi-Fi to work.

Dash message says I have no data plan which as stated, I do. Tells me to connect to OnStar to get one, so of course I press the blue button, and it says it "Cannot connect to OnStar". So what if I were really in trouble, what if I were in an accident, would it still not connect to onstar?

I have contacted both OnStar and the dealership, who said I am supposed to be charged for a required software update, but that didn't work anyway. Now seeing if I need a module which I may or may not have to pay for. This is been an issue since I purchased the car new and I have an extended warranty that was supposed to cover such issues as "electronics". I'm tired of paying for two services, yet having to choose between them. Call OnStar on my telephone because of course the blue button doesn't work, each time they tell me to stop my car, turn it off, open my door for 2 minutes at least (I'm using my remote start, so it's probably also cold), then restart normally. Which we already discussed that of course it will work then, because I'm not using the remote at that point. Then they insist on running the same old diagnostics which has nothing to do with this problem and btw, yes I knew Im due for an oil change, but there is still no resolution. Seems like with all these complaints, GM would figure something out

Same exact problems!!!!!  Well explained!!  Hopefully someday they'll figure out it the problem 🙄

I recommend everyone here sending an email to the social media email above to get some eyes on this issue. It's clearly a systemic software bug and not a 1 off thing. 

My 2020 sierra does the same thing. Virtually every time I remote start the vehicle (via app or fob), when I get into the vehicle and hit on button, wifi is non functional. Which is frustrating because it means I can't stream music. 

I noticed when I go into the on star page, it does not seem to be linked to my account as it shows no account but states it has a data plan, but it doesn't work. The only thing that works is turn truck off and open door, and wait for 3-4 minutes and then turn it on. It's very frustrating that this happens nearly every time. 

What's more frustrating is that GM has a button combo you can hold to reset the head unit on models before 19-22 and on the new 23+ head units but absolutely no way to reset it on 19-22 without parking the truck for several minutes, which is frustrating when you don't realize the wifi is not working until you get in it and start driving. 

Please fix this issue. It's been a problem for years. Clearly something with the head unit not connecting properly when remote starting.

It is now 1/14/2024 and nothing has been done to fix the problem on my vehicle, even though they told me they would keep my case open for the fix. Is anyone actually working on finding a fix or are we all just getting blown off ?

It is possible there could be an issue with your OnStar hardware. We'd have to look further into your account to understand the errors you are receiving to know for sure. If you are still having trouble with your WiFi, don't hesitant to contact an Advisor at socialmedia@gm.com or by pushing the blue OnStar button within your Silverado.

Same issue; 2020 Traverse. Same response; Call Onstar / Reset signal / Wait it out.

In Canada, we don't have great wifi plans so doesn't interfere there, but it does remove the streaming SirusXM stations.
