[Q] wifi keeps disconnecting for no reson

I use cm 7 and have no other mods installed on the phone but for some reason my wifi keeps getting discounted then after a few seconds it will come back on then off again?

Look for adv wifi settings and set sleep policy to never. Thats what I do on my droidx2 FWIW.

Did that and still have problems.

Just check out this thread. Might help.

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.

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.

Great info thanks.

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]

[Q] Wonky GPS on AT&T S4?

Hi all. I'm having a bit of GPS weirdness. GPS can get a lock quickly and accurately, however, I have to turn it off/on every time I open an app that uses it. Otherwise, it won't ever find the location. Once I turn it off/on it picks up and stays locked while the app is running. Also, if I switch to another app that uses GPS I have to do the same thing to get a location fix.
So obviously, the GPS function works, but something in the OS is not recognizing it until it's reset. Not the end of the world, but definitely annoying. Is anyone else seeing this?
This is on the AT&T version, by the way.
Thanks!

Check if you have GPS and Mobile Networks turned on for Location.
Else return it.... and get a new one... GPS has been quick and spot on...

GPS is quick and spot on. Per what I wrote, I have to turn it off and on for an app to be able to use it.

I've noticed this once, where something in the background was starting a GPS lock, but seemed to cancel, and retry before it ever succeeded. Turning the GPS and location services off, then back on worked for me. Haven't had an issue since.
If you haven't tried resetting to factory default, I suggest doing so.

Well, I was hoping for a bit more granular approach than a full reset. I'll wait until the new OTA is applied before doing anything drastic.

Less drastic than returning it. I suppose it depends on how attached you are to your current setup - but I would say if you're experiencing that issue repeatedly, the factory reset is exactly what you'd need. I doubt the OTA will address it since it appears to be an isolated problem.

Be my guest but to get the quickest results please just turn off all gps settings then do a battery pull. Restart it and turn the gps services back on... Viola
If that's to drastic for you then your SOL

You can also try to download GPS Status from the play store and download aGPS data and see if that helps

Nope, the issue is with ANY app that requests GPS data.

So, yeah. Today's OTA update did indeed fix this. i would press my own Thanks button, but that would be sinning!

Same issue here and it's driving me INSANE. lol I am on stock rom just rooted and unlocked. If i ever want to use Gps I need to turn on/off the toggle. Very annoying. Wasn't like this from day one so something must have changed. I have tried clearing the cache for Google Maps as well as re enabling all of my location settings downloading aGPS data data did not work

Do you have yahoo weather installed ?
Sent from my SAMSUNG-SGH-I337 using Tapatalk 4 Beta

I do not have yahoo weather installed. Another bit of info I forgot in last post:
I do sometimes, in a quick glance, see the gps icon running out of the blue. The notification of "acquiring gps signal bla bla" is present as well.. only to disappear within seconds. So it seems as if a specific service or application is using the gps in a faulty manner, blocking other services/applications from using it. May be why resetting the gps allows the application your trying to use access it. (my only fix)
If someone could read a logcat of what's going on I could post one up
Sent from my SAMSUNG-SGH-I337 using xda premium

I've actually been combing through the logcat output and see a line reappearing often referring to "no secgps file" I do remember on my previous devices messing around with that file and others for GPS configurations. Does anyone know if this file is supposed to be included in the stock rom?

Seeing a few other posts in this sub forum for GPS locking issues, and most the others see the fix to turn on and off via the toggle.

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 function fail (turning off involuntarily)

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.

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

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
