Cellular to WiFi when signal is weak
My iPhone 15 doesn’t switch to my strong WiFi signal when the cellular signal is weak.
why?
iPhone 13 Pro Max, iOS 17
Is your iPhone set to auto-join your WiFi?
Settings->WiFi->Ask to Join Networks. If the option is off turn it on.
You could also try “forgetting” your WiFI then logging back manually.
For what it’s worth my iPhone 13 switches to my WiFi the minute I walk in the door. That’s what it is supposed to do.
