My phone internet has been unstable ... I have to turn airplane mode on and off to be able to have internet. I called At&t and they said it might be because of the software updates... any one with the same problem?
You can actually reset your network settings is what I would do. And then you can change it from randomized Mac to phone Mac ID and then restart your phone I had similar issues and that helped a lot. Also if you're using Wi-Fi you can check send device name to network helps also.
If you have that issue and you are att i will tell you 100% switch your sim card to new one i had that issue before on my S21 ultra. Most probably your issue should be fixed. That is the first thing you should try before any other options
