    1. Hi, may i know which iOS version you are using and your iPhone model number? I have tested this technique in my iPhone, friends iPhone and it worked very well. Thanks.



    1. Ok. I know its going to take some extra work for you, if the Reset Network Settings didn’t help, give a try with iOS 9.3.4 Fresh installation. try it on any one device first and if it works you can download the full iOS 9.3.4 for other iPhone as well.

      Connect your iPhone to iTunes and take backup before downloading and installing a fresh copy of iOS 9.3.4. This should definitely fix the problem with frequent WiFi disconnection.

      Please let me know if that helped.
