Why is my iPhone 4S's Wi-Fi greyed out?

I bought a new iPhone 4S off Ebay in March, and originally had the same thing when I got it, but over the summer, the Wi-Fi was working fine. Now it's greyed out again and I've tried all of the steps on the Apple website to get it to work, including resetting my whole iPhone and it still won't work. I'm going to ring Apple at some point, and I'm now not gonna buy an iPhone again but I was wondering why it decides to grey out so you can't use it?

Just follow these steps and your Wi-Fi should work fine!

1. Reset the network settings by tapping Settings > General > Reset > Reset Network Settings.
2. Ensure your device is running the latest version of iOS. You can check for updates in Settings > General > Software Update.
3. If all fails, do a software restore in iTunes.

Hope this helps!

  • Why are my Itunes Tone ringtones Greyed Out? My tones appear under the "Devies-Iphone" section but not under my library. Also under the "iphone-Tones" section they are greyed out and will not let me drag or drop them anywhere? They were bought from itunes! Off of my iphone! So No, they are not illegal!
  • My iphone 4s has a greyed out no wi-fi? I own an updated iOS 5.1.1 iPhone 4s. Just yesterday it wouldn't connect to my friend's Wi-Fi. Now it won't connect to any Wi-Fi and just says "No Wi-Fi" and also won't let me click on it at all. I've tried resetting my network settings, resetting all of my settings, and even resetting with the home button and hold button.
