Wi-Fi for iPhone 4S blurred out?

I'm just causally using my phone and I noticed Wi-Fi isn't on. I go to turn it back on and bam it's blurred out. I turned off my phone and even hard reset it when you hold the power and home button. If I back up my iphone to my computer and factory reset it to brand new will it start working again?

If its a software issue it should work after you restore it. If its a hardware issue you need to repair it.
