My 2019 Blazer Premier has recently started saying "No Network Connection" I thought this was an AT&T issue, but upon turning the vehicle off and back on it reset and started working. That was a few days ago, today I was going to the West side of town and just left the garage and "No Network Connection" so I had to pull over turn OFF the Blazer and restart it to connect the internet provider. They really need to update the Infotainment software so some of this stuff goes away. Of course without internet connection it won't update anyway.
