My iPhone 12 Pro has been in and out from WiFi and 5 G for months, causing text messages not to send or my log on to internet to fail. But my husbands iPhone 11 never has a problem.

Perhaps a long shot:
Do you have a 3rd party VPN installed, even if you are not using it? If so, delete the VPN profile in Settings/General/VPN & Device Management/VPN, then restart your device. Don't just turn it off; delete the profile. Updates sometimes "break" VPN, and it needs to be removed. If that fixes it, you can try reinstalling VPN, but probably shouldn't.

No, we used to but not now. I just checked.
I can try the update but actually I had problems after a few updates ago
