Simply turn off "Ask to Join Networks" and you will never see the WiFi popup you refer to.
I believe having this off is default behavior since at least iOS 9.

I always had this option off. Now I went into settings and see that it's on. It's frustrating that an upgrade changes things and also requires the user to take specific actions to get it back to how it was (after the upgrade, I had to sign in to the App Store, to Game Center, and a few other things that were already setup).
