Anyone else having issues with the wifi turning off on its own? Got my S5 yesterday on AT&T. There have been a few times that the wifi will turn off and it can't be turned back on unless I restart.

I've experienced this with wifi settings as is out-of-the-box and when I changed the option to only have it on during sleep while plugged in.

Wi Fi involuntarily turning off and cannot turn on without rebooting
I'm having the same problem. S5 goes to sleep when waking the wifi is switched off and I cannot turn it on in settings. I have to reboot

Try this, go into settings, press wifi, then press the button consisting of 3 dots in the top right corner and then press advanced. where the settings state "keep wifi on during sleep", make sure it is set to always.

also check the wifi timer is not on either.

Let me know how you guys get on

Yes, that's the problem. It is fixed by not using the feature... Great, isn't it?

I have the exact same issue and am thinking to call warranty and see what they can do. This happens on any router, very annoying. You can avoid phone restarts btw, just put the phone in airplane mode and back in normal, when you do that it will be able to turn wifi back on. I am wondering is this bug on every att galaxy s5?
this bug occurs when you have the keep WiFi on during sleep option off. this saves a lot of battery, and to me avoiding this option isn't a fix to the problem, because on every android device I have I make sure WiFi turns off during sleep and never had issues reconnecting back when I wake up the device but galaxy s5 has that issue
