Iphone 15 Pro stops connecting to Wifi & Cellular networks - Unreliable phone issue!

Do you use a VPN on your iPhone? If you do turn it off, or better yet, remove the VPN completely from your phone. They are simply unnecessary on iPhone and often cause issues like you're seeing on your iPhone.

I don't know anyone whose phone iOS 18 caused Wifi or Cellular to turn off. Saying Apple needs to fix something, which is not a universal issue won't help you.

My wife and I are having the same exact issues as the Author of this post. Both of us have a iPhone 15 Pro Max and have been unable to connect to our home wifi and even our cellular network (Verizon) since waking Sunday morning. Our connectivity with every other device (TV's, tablets, iMac, Macbook, Ring, etc) in our home works perfectly fine. I've also tried restarting our modem and router multiple times, restarted our phones, shuffled airplane mode and even Cellular Data on and off, and reset Network Settings. Also like the Author, a VPN is NOT running. I've attempted every hack or suggested fix I can find with no results.

Completely unresponsive response. How dare you insinuate this is a user issue and not an Apple issue when many people have the same thing, and shortly after “upgrading” to iOS 18.0? Those of us who have a $1400 brick are ******. Further, for you too insist that a VPN iOS to blame and not even necessary is insulting and shows your knowledge pool is pretty shallow. I’m returning mine to the store today.
