Wifi function fail (turning off involuntarily) - Galaxy S 5 Q&A, Help & Troubleshooting

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

Wifi turns on by itself?

It seems that every time I plug my s4 in, it will turn on Wifi. Then when I turn Wifi off the phone tells me "unfortunately smcc service had stopped working". Is anyone else having this issue?

I'm having a similar issue where it turns itself back on when it's turned off. This is happening even when it is not plugged in though I'm not seeing any errors when turning it off.
It is the Smart Mode located in Settings under Wifi.

That may be it. I just turned it off. We'll see what happens. Thanks!!!!!!!

Ahhh! My brain fart has been sprayed with Lysol..! Thanks Crawrj!
If that doesn't work check for a setting called "Connection Optimizer." I haven't gotten my S4 yet but on other Sprint phones it is Settings > Mobile Data > Automatic Connections > Uncheck "Connection Optimizer"
It's supposed to intelligently determine when to turn wifi and 4g on and off. Connecting to wifi will save battery over mobile data so it is best to connect to it, that's probably why they have connection optimizer on phones.

THANK YOU! After reading the description this does appear to be the culprit. And the longer you stay in one place(work) the more aggressive it seems to get.

It's not in 4.2 on our S4.

Ya it took me a min to figure it out. It's designed to read your location and connect to wifi in areas your always connected to wifi. But if you wish to shut it go to too:
Settings > Wi-Fi > Smart Mode > turn off.

Me too. Thanks so much for this. It was driving me mad. Up next: preventing it from disconnecting because it feels the wifi is too slow. UGH. Walking around my building there are good spots and bad spots. If I sit in a bad spot too long I am disconnected with no hope for auto reconnecting. Maddening.

Juice Defender vs. Smart Mode
I use the WiFi location-based trigger in Juice Defender instead of Smart Mode.
As I understand it, while Smart Mode tries to turn on WiFi for ALL of your common locations, JD can do this on a location by location basis. So, I don't like to be connected to WiFi at work, but I *do* at home. JD allows for this.
Sound right?
Thanks,
Eph
I have Smart Mode off - but Wifi still seems to come on at least once a day?
What else could be triggering this?

Not to sure. Happens to me once in awhile too. I'll go to turn on Hotspot and it says it needs to turn wifi off when I have Smart mode off. [emoji85] [emoji86] [emoji87]

My Nexus 4 shows the same thing unless I actually turn off the wifi. I just leave my wifi on so when I come home it auto connects.
Weird minesays the same. I had my wifi off for at least 5hours

You have to go into WiFi settings and select one of the other features in advanced settings
TWEAKED 2.5
Because your WiFi radio keeps actively searching for an active signal unless you turn it off.

I believe the option in the advanced settings is "Scanning always available". If you turn that option off it should stop.

Simple, because the WiFi radio is on.
I have found WiFi battery usage to be very odd on the Note, at least Note 1. I used to have it turn off on screen off (settings default), but that caused battery drain. I then used Llama (Location Aware Mobile App?) to turn it off when the screen was off after a minute. Still drained.
I eventually left it on all the time I was at home or work, and it was much, much better. I guess going on and off all the time was the drag, or caused another issue.
I then used Llama to turn it off whenever I leave home or work, and turn it back on when I arrive. Happiness achieved.
I just drag down the notification bar and hit the toggle. One less active app to hog memory and battery...
Then again I also turn off mobile data when it is not needed. That spares me a full 4 days, and that's just on the s3. Imagine how long a note3 would last... (I'll know when my order finally arrives...)

Thanks for this! I thought I was going crazy earlier as I knew I switched off wifi!!!
Got to work and saw it on lol!

Wifi Issues: Keeps Turning off & On

I've seen other people having issues with wifi but haven't read of anyone finding a fix. I'm watching the on/off switch go back and forth as my G2 continues to try and establish a connection. It connects to my router for a second, then disconnects...This has been keeping up all day.
Any suggestions?
Already reset my router. Tried to WPS push button method.

Did that. Nothing. Also tried to connect to the public wifi at work, same problem.
turn off battery saving stuff like switch off wifi when not using
Has anyone have a solution to this?
My G2 did the same thing as the OP says. It will turn itself on and off (about 5 second between each on and offs) but ONLY if the bluetooth is turned OFF. If the bluetooth is ON, no problem whatsoever. I usually left my bluetooth ON because I have a bluetooth headset and I want it to be ready every-time I want to use them. But, this night, when I turn off the bluetooth, the wifi keeps going on and off, and yes, battery drained and no internet connection for me
Please help if anyone have a solution for this. I'm in stock rom (D802) 4.4.2 rooted, with xdabbeb's camera mod, the only "root" apps that I've installed so far. Reboot and full power off is the first thing that I do, still no cure.

Sorry for replying to an old post, but I have exactly the same problem here, only difference is that in my case, charging stoped at 66%. I changed the battery, the charging issue fixed but still have the wifi/bt issue.
I flashed stock kk rom, and 3 custom roms with kk, lp and mm base, nothing..
Thx for any help.
Edit : my phone is a D800
WiFi issue is still there

Is your location services by any chance set to using WiFi, Mobile Data And GPS? If yes, turn it back to GPS only.
Done that, even tried disabling location service no joy

try turning off the network auto switch perhaps?
you can find it in Mobile Network section in Settings
I tried that it works partially, in a sense, if I turn off wifi, it brings on mobile data, but the main issue is the wifi is getting turned on in seconds of being turned off manually

Anyone experiencing constant WiFi disconnects after 7.0?

I mean, I'm seeing my Wi-Fi disconnecting and reconnecting seconds later probably every ten minutes or so. It's getting infuriating. It's not my home network, either, as none of my other devices are experiencing this issue. Even still, just to be sure, I've tried multiple reboots of my router, to no avail. Anyone else having similar WiFi issues?
I been having the same problem with wifi. It will be fine for a while and then randomly disconnects and reconnects. Im not sure what do do about it. Other than that, i have had problems with quick connect...cant connect to my tv anymore
Same

my wifes s7 edge does this but shes actually still on MM
I had the same issue. I performed a factory reset then used Smart Switch to re-install everything with the exception of apps. I had to manually select and install them (this was recommended from another post to avoid battery drain) and no issues again with Wi-Fi auto disconnect
I'm on AT&T and I have WiFi disconnects frequently. When the phone sleeps it always happens... And yea, I have the always on enabled.
.. Really annoying

My Data Saver was OFF ... you saying turn it ON and it fixes Wifi so it does not sleep / doze when screen is off?
Turning it off on mine fixed the issue. You may need a factory reset
