iPad can only connect to public wifi but not private wifi
Hi all. My ipad cannot connect to any private wifi installed at home or iPhone's personal hotspot. It can only connect to those public wifi available in school, restaurant or Apple store, etc.
A network setting reset / factory reset / recovery in iTunes / recovery in DFU mode / reset in router cannot solve my problem. The problem has persisted for a few weeks, before that everything is working perfectly fine.
Does anyone know how to solve the problem? Or if there is any way to manipulate the settings in my router to make it function like a public wifi? Much appreciate your help!
