Wifi will not turn on all of a sudden in my S4.

Started on 6/30/14. The wifi icon, will turn a dull green when touched for about 15 seconds, then it goes back to grey and won't scan or turn-on. It was working just fine the night before. On 7/1/14, it worked briefly (for about an hour), then it stopped and hasn't worked since. I did not updates, app downloads, etc recently.

Oh boy! We want to make sure you are able to access WiFi again, columbine8. Can you try WiFi when the phone is in Safe Mode http://vz.to/15rkFOi?

the WiFi worked in Safe Mode. When I turned Safe Mode off, it was still working for a little while, however, I notice as it re-loaded apps, the WiFi disabled again. I wonder if I should try Safe Mode again, and turn it off again, but pay attention to which app was re-loaded when the WiFi quit working?

I re-did Safe Mode, the WiFi did NOT turn-on this time, however, when I turned Safe Mode off, the WiFi DID turn-on. I went and uninstalled all the apps that were most recently downloaded from my phone. It's been about 30 minutes and it's still working so far (fingers crossed). I'm cautiously optimistic the issue was in one of those apps I removed.

well, problem is NOT solved. The WiFi will only stay on for about 30 min to 1 hr in both safe mode and regular. Sometimes it will turn-on, and sometimes it won't. Now I don't know if a factory reset will help since it won't even stay on in Safe mode. Please advise

Has anyone figured out this issue? I have the same problem on my S4, WiFi will not turn on. Goes light green then back off. This is an intermittent issue, sometime it works. But only for a little while. Seems to be more consistent if I turn on WiFi but there is no network to connect to; it.e. then the WiFi actually comes on.

However, it is totally random and has been for a couple of months. However, at this time it does NOT work most of the time, so it's a problem.

I also tried the standard stuff - pull battery while phone is on, turn off phone for 30 minutes, etc. Nothing has worked. Also, it makes no difference it my phone is in safe mode or not; WiFi does not toggle on in Safe Mode either. Searched the internet for hours last night and this is not uncommon. However, seems like even those folks that rooted have not solved this issue.

My phone is out of warranty. Without working WiFi it is somewhat useless.
