After my restoring my iPad on iOS 7.0.4 through iTunes, the wifi option is always off and greyed out. I'm pretty sure it's a software issue because the wifi was working fine before the restore. I'm aware of this being an issue on iOS 7, but only on iPhones, and usually a hardware issue. I'm kind of hesitant to try thowing it in a freezer... Any ideas, guys? I've tried restoring it already, thanks! FYI, celluar works.
