My iPhone 4S suddenly is unable to connect to WiFi. We went thru the process of restoring the phone, but it will still not let me connect to WiFi.  I see a number of people complaining about not being able to connect, is there some sort of a fix ?

If WiFi on off button grayed out? Or can you not connect to any WiFi in different locations? If it's grayed out after full restore your WiFi antenna is done so you'll need new equipment. Under warranty?  Apple store can replace

Yes my WiFi on off button is grayed out and I cannot connect in any location and it is still grayed out after a full restore. Thank You for your input.
