    Welcome to Android Central! When you go to Settings>Wi-fi and tap the toggle, does it move at all? Is it greyed out?

    Try wiping the cache partition: https://support.t-mobile.com/docs/DOC-27393

    It could be a problem with the firmware, or a hardware issue with the wi-fi radio itself. You could try reinstalling the firmware using Samsung Kies: [GUIDE] Force Samsung Emergency Recovering with Samsung Kies
