Galaxy s4 Wi-Fi authentication issues - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

Hey guys,I was wondering if anyone else is having issues with there Wi-Fi staying connected? Mine will randomly drop and u will see 3g and when I go to Wi-Fi,I see an authentication error has occurred.
Its pretty annoying. locking the phone and than turning it back on will fix it but than it just happens again.sometimes hours later sometimes, right away. I did some Google searching and saw a few other people have this issue but none of the threads have a definitive resolution. I am on stock rooted rom and had the issue before I rooted.I also haven't done the mf9 update yet so I am still on mdl.any help would be great!

I am on mf9 and no issues. Is this only happening on one router? If so maybe its a router issue.

No it happens on allot if different routers,I googled the issue and see allot if different people have the issue but no solutions that I can find. I just updated to mf9 and I still have the problem.if I rest the router it works just fine for awhile.wet have many different devices and the galaxy is the only one with the issue.

I think it's an issue with the mf9 kernel, if you are rooted try flashing a custom kernel and then wiping cache & dalvik then fix permissions then reboot. that should fix the issue. if you are not rooted, i'm not sure what you can do other than take it in to sprint and see if you can get a new device.

apparently has to do with wifi power save mode
you can turn it off by following the instructions
dialing *#0011# which takes you into"service Mode",,, then pushing the menu button and selecting (at the bottom) the "Wi-Fi" option from the pop-up,,, then the toggle "ON/OFF" for wi-fi powersave
you will have to redo this after a reboot so I just save *#0011#as a contact to easily pull up when I need to

Help!
I did the *#0011# thingy then nothing happend, it's still saying "saved,secured" sometimes "Authentication error occurred".
is there any way to solve this problem? T.T

** make sure you have the correct password saved for the network your trying to.connect to.. id click it.. then hit " forget ".....then try to re-enter the password again....

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 was having this problem earier for a while if you go into the nttings menu and go to wireless networks unclick and click the check bow to enabled and disable wifi that fixed th problem for me.

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.

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.

Mobile data connection doesn't work after using WiFi. Only after reboot

Hey guys,
I am using ICS Evervolv a5 on my N1. The mobile data connection works only if I don't connect to a WiFi network. If I do, the only way I have found to make it work again is to reboot the phone.
This means that while I am at home, everything works through WiFi, however, if I leave home, I have to reboot my phone once I am sure the phone is far enough from my WiFi access point to be able to connect. Then, it starts working with the cellular data plan
The only thing I can relate to this is that I have the "application protection" app installed, protecting the settings menu do with a code so my kids don't mess up with that. However, is still hard to believe that's the culprit.
Thoughts?

I too had this problem when i updated from 4.0 to 4.1U2. I tried couple of things like clearing cache/dalvik cache etc. nothing worked.
Later i used 4EXT Recovery to format all except fat32. After this i did clean install and things are working fine
Do you just have gray bars or is the connection icon showing an x?
I had the problem that I could not connect and I had to clear the data of the Google framework to get it going again.
But that might have been another problem.

Try turning airplane mode on and then off, so you don't have to reboot the phone. It works for me.

I am getting the gray bars. It seems that is working these past couple of days. I will try clearing the data from the Google framework the next time it happens..

I noticed that I was getting grey bars over the last few days too, but using CM7. However it corrected itself yesterday. Perhaps it's something external causing it?

Just a quick note, i guess most people on xda know this but if not, you could try to use an app called catlog or other similar apps.
You can find out if programs are behaving badly by using it and by Googling errors you often find the solution faster.

after switching from wifi if the data doesnt work.
just put ur phone on airplan mode for few seconds and back to normal network mode

[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

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?

WiFi hangs and drops

Hi
I'm currently having a problem with my S4 that is driving me mad.
Ever since I got the phone I've had a bit of a problem with the WiFi connection. I've flashed a few kernels and some seems to help the problem more than others but it's still there.
What happens is the phone connects to WiFi no problems. Then maybe after a few minutes of use the phone won't give me any data. If I search a Web page it just hangs and then says unable to display web page. I then have to knock the WiFi off and back and and it cures the problem temporarily.
Sometimes the WiFi connection can be fine and last a few hours without hanging. Other times it can last a few minutes. The WiFi icon always remains on the screen and the arrows act as if data is getting processed but nothing ever happens. The odd time it will also kick itself off the WiFi and reconnect.
It's driving me mad having to constantly knock it on and off. I'm missing WhatsApp messages for hours because of it also.
Is it a common problem? If not the phone
is still under warranty so I will have to send it back but then that's me phone less for god knows how long
Any help would be great.

if you are rooted, flash this http://www.adrive.com/public/8DJWtV/WifiFix.zip
its a fix that sorted out my wifi problems
I think you should revert back to the latest stock and reset your modem. There might be some fancy settings in your modem software that need to be turned off. I read that somewhere but can't remember which ones. Just search on here.:cyclops:
Hi guys, sorry I've just seen the replies and thank you for taking the time
I shall have a blast at both your solutions and report back.
Thank you again
Well I tried the WiFi fix but that hasn't cured my problem. Today I will flash to stock rom and then re-root and see if that makes a difference. If not its off for repair under warranty and the old Nokia 8210 will be coming out of retirement for a few days lol

Hi jehbrian.
I've never heard of this fix but I'm willing to give it a go (whats the worst that can happen lol).
Done the above and indeed you get to a point where Wifi power saving mode is on. I've knocked it off and will see how I get on in the next couple of days. It does make sense that the power saving mode could be killing the Wifi every now and again.
Thanks for the tip and have a pleasant day :fingers-crossed:

Does it?
Surely there must be something else that can compensate for this loss if it means the Wifi actually works. GPS? Bluetooth? Screen brightness?
My phone is on my dock so can't verify the loss of battery.

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.
