Wifi not available after updating to iOS 10.2
Let me start off by saying this is a customers ipad and not my own, she updated her ipad to 10.2 and now does not even have the option of even turning on wifi(wifi was working perfectly before). i have reset network settings and have done a restore. i can not erase the ipad in the settings because it asks for the apple id and password (which i have and am sure are the correct credentials, having logged into iTunes) and since the ipad is not connected to the internet, it fails to communicate with the apple id server. i was wondering if anyone had a similar issue and or knows a fix for this issue.
Esta é uma boa pergunta?
