How do I revert to a previous iOS version on iPhone 6s to fix Wi-Fi and mobile data issues?
My iphone 6s was updated to ios 15.4 recently but will not stay connected to my home wifi .
It no longer gives me access to mobile data
How do I remove it, save all my information and revert to an update that doesnt cause issues
I am not the only person who has had this issue
