No wifi - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

Guys I'm trying to fix my daughters phone, I've looked around and I tried a few things to no avail.
The issue is the phone is on 4.4.2 nb1 from an ota update. The phone used to be my sister in law's. Before she gave it to my daughter she did a factory reset and now Bluetooth and WiFi both won't turn on. No matter what you do.
I tried to Odin a stock nb1 image to see if maybe the ota update was corrupted or something but it only starts and runs for like 2 seconds before it will just hang and do nothing.
Any ideas?

Has anyone ever had a problem to where the WiFi wouldn't turn on?

Try turning wifi power save mode off. Dial *#0011#, press menu then wifi and then switch it off and see if it does anything.

Wifi Error?

Anyone else getting a WiFi error randomly? I'm using a pre-rooted version of EC05 and use Barnacle WiFi tether sometimes at work. Sometimes I can fix it by enabling airplane mode then enabling it but it's about 50/50. Other times I have to reboot. Anyone know of another fix?

I have this same problem as well from time to time. It started when I upgraded to EB13 and it still happens on EC05 as well for me, I'm running the stock rom that is rooted with one click.
I have had this problem since EB13 and it's also on EC05. I have even tried clicking the WIFI under network settings as well and it still errors out. Sometimes it takes a few seconds to show the error notification, other times it may take several minutes. I have tried turning data off and on, airplane mode off and on and that may work 50/50. The only reliable way to get WIFI to turn on has been to reboot the phone.
Running stock rooted EC05 done via manual update from EB13.
Having this can't he issue a well. Mine requires a reboot

I get this. Mine's not random though; it never happens the first time I try wifi after a reboot and it almost always happens if wifi has been turned on and then turned off again at any time after a reboot.
I can usually get it to turn on wifi after a couple of tries if I use "wifi settings" to turn it on. It almost never works if I use the toggle on the little drop-down menu. The annoying part is that if I click to turn wifi on, there is a long wait until it will show "Error," and I can't retry wifi until that happens. I'd say maybe 10% of the time, tops, do I need to reboot.

Should I try reflashing the EC05 modem? I updated from EB13 to EC05. Should I use the modem from the EB13 to EC05 update or would using the DI18 to EC05 modem work as well? Odin or CWM the modem? Still learning flashing so please bear with my newbness.
OK just downloaded the EB13 to EC05 modem and flashed via CWM. So far i was able to turn the wifi on and off multiple times with no errors. We'll see how it goes in the long run.

I also experience this issue often. Its starting to drive me crazy.

In the same boat as everyone else here, and after re-checking any pertinent threads it still does not appear that anyone has found a proven fix.
Besides flashing the EC05 modem, any other ideas?
Can anyone who flashed the EC05 modem report their sustained results?
Thanks!
I still get a WiFi error with the EC05 modem.
It generally presents itself when I'm downloading data via 3G and then switch to WiFi. Without exception, all I've done is go into airplane mode and back again and close the app through Task Manager (dolphin, market, etc. whatever was using data) to get it working again.
I get this as well. I just go in airplane mode and try it again. Then it works.
same issue here.. when i leave the house i turn off wifi.. when i get home it almost always times out and i have to reboot the phone
I don't know if this will work for everyone, but I've found that decreasing the beacon interval on my router's settings completely got rid of this issue for me.

I haven't had the issue you are speaking of. I think that a reflash of the ROM may fix it.

Anyone know why I lose mobile connection every 10 seconds?

I am on AT&T, and every couple of days when on mobile data, my data will cycle from connected to not-connected every 10 seconds, making using the data useless. The only way I have found to fix it, is to turn on airplane mode, and then turn off airplane mode, and then it connects fine. I have looked at my logcat, but I do not see anything. Anybody have any ideas?
Thanks,

what ROM, kernel are you using.
people seem to never add it into their signatures anymore. thats why people do it for a reason, so it helps debug problems.
Sorry, and latest faux kernel and stock rom.

I have the same problem on stock rom and kernel. It's worse in NYC vs. Connecticut. I think it's also causing msm_hsic_host wake lock which is killing my battery.

Completely stock and same problem. Airplane mode toggle is my only fix too. It's got to be a software issue.

This is probably the simplistic explanation, but may not be the case: faulty SIM card.

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.

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

Location method problem

When I switch to 'Power saving' mode under Location method, my GPS is switching on too. But, Power saving mode is WiFi + mobile. When I switch off GPS, the whole Location thing is switching off.
I can't find something about this, so maybe someone has an idea?

Try resetting the phone by taking the battery out when on
Thanks, but didn't help. And I already have done a factory reset and formatting

Sorry I guess I misunderstood your question...
If you tap off the toggle that says GPS, yes that turns off all locations services... Is working as designed.
Really strange.
I got 3 options.
1. High accuracy (wifi+gps+mobile)
2. Power saving (wifi+mobile)
3. GPS only
You're saying, that option 2 is not existing?
It should only use wifi+mobile. NOT gps.
So it's not working properly. Before the update to NC9 firmware, it was working fine.

Quoting you..... "When I switch off GPS, the whole Location thing is switching off"
Yes that is how it works, if you tap the GPS toggle from the notifications......
Now... for this..."When I switch to 'Power saving' mode under Location method, my GPS is switching on too" let me do some test and get back to you...
Well, yesterday I flashed back to the NC4 firmware and it's working again
Sent from my GT-I9505 using XDA Premium 4 mobile app
Flashed another NC9, and again the same problem. Guess that's why there are so few NC9 firmwares.

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
