MY WI FI IS GREYED HOW COULD I SOLVE IT
iPhone 4S, iOS 8.1.2, DNQHRJPZDTC0
This is the only support document that Apple has for a grayed out Wi-Fi. iOS: Wi-Fi settings grayed out or dim - Apple Support
The final step in there is to contact Apple Support for help.
And if that still doesn't work, one last step to try is to restore it as new. It's not in that article, but if your device needs replacement, backing it up is an important step. Once you've backed it up, it's a simple matter to erase the device and set it up as new: [How to erase your iOS device and then set it up as a new device or restore it from backups - Apple Support]
AS I MENTIONED MY PROBLEM IN APPLE STORE PERSON SAW SOMETHING IN GENERAL SETTING AND REPLIED IT'S A HARDWARE PROBLEM THIS MAKE ME LITTLE NOISY.
If following the steps in the support document do not work, then it is probably a hardware problem. They were right.
