last night while I was using my phone, it automatically did a hard reset and every since I have been unable to turn WIFI on. I've complete reset and restored and reset as a new phone. Still the WIFI is greyed out
iPhone 6, iOS 10.2.1
try this
If Wi-Fi is grayed out or dim on your iPhone, iPad, or iPod touch - Apple Support
and also check restrictions
Settings>general>restrictions wifi can be disabled and that can cause it to be greyed out
Use parental controls on your iPhone, iPad, and iPod touch - Apple Support
Make an appointment at the genius bar. That sounds like a hardware failure.
I appreciate the thought but restrictions were already disabled.
WIFI disabled on iPhone 6
