Can't turn on my WiFi?!?! I've already done a factory reset :( HELP!

Question

I got a system update this afternoon and now my S4 wont let me turn on the WiFi 
  I did some reading online and read that you have to do a factory reset if you've tried rebooting your WiFi at home and still nothing  My computer connects to the wifi just fine....Anyone else??

Try this.  From your home screen tap Menu>Settings>Wifi>Tap Menu again>advanced and uncheck the Autoswitch Network opiton.  Now hit back and make sure WiFi is switched on.  Find your network and tap it.  Tap forget.  Let it rescan for a network and when yours pops back up, tap it and set it back up.

Hope that helps,
