[Q] No wifi - Galaxy S III Q&A, Help & Troubleshooting

Hey guys
The wifi on my galaxy s3 just randomly stopped working. I was sick for a week and just left it in the car, and when i got it out, it kept turning it self off and wouldn't connect to the wifi. Instead of just not being able to connect, it cannot scan for wifi availability. It just turns off. Everything else works fine. I've restared and completly cleared the phone. I have no idea what is wrong with it, nor how to fix it. Any ideas or suggestions???

Flash full stock firmware and factory reset, if still the same then it's a hardware fault.

Anyone?

Yup, had this problem after applying this OTA.
When I click the checkbox to enable wifi, it just shows "error" and does not enable wifi.
A factory reset fixed it for me.
My wifi turns on and connect but won't give me any data

The Atrix has a driver related issue that causes problems connecting to WiFi access points in certain countries. I'm pretty sure they have figured out a workaround over in the Atrix XDA section, sorry I don't have a link for you.
Hi,
My name is Fisher, I have the same problem, I have the phone in Australia and I updated over wifi then my wifi just says error underneath it, also 4G does not work. I can turn wifi on by first putting the phone into aeroplane mode then restarting and turning wifi on while still in aeroplane mode. I have managed to get all working occasionally by having aeroplane mode and wifi on, then going to system updates which are greyed out then turning off aeroplane mode by holding down the power button and when ive done that i have a second or so before the wifi dies to click motorola software update that is now not greyed and it sometimes kicks everything on;-)
I have tried factory resetting the phone 3 times and formatting internal sd on third time, did nothing.
Now i have some dmesg logs with the wifi under error, working in aeroplane mode and all working with my trick, so let me knowif u want them all.
I have a feeling the issue could be a sprint app or process that disables it, look at the access/security settings for sprint zone, it can control wifi, everything seems to be briefley activated when i start the phone in the notification bar then wifi and 4g die, so maybe a sprint process detects that the phone has not activated or something and kills wifi and 4g.
I have reported this on the motorola forum in the thread someone else started, look for " motorola photon wifi error" in google and it might be the first hit.

Sounds good. Ill give that a shot. Lemme know if you find out more
Mine is working fine, though today I turn WIFI off and my battery had a run away effect. The battery drained 30% in 10 min and the phone was at 116 degrees. It also rebooted itself twice but now it is fine and I turned wifi on and off a few times and no ill effect.
and yep I have the update.
Wifi ERROR after OTA update
hello everyone
i am not a US resident and i bought this amazing phone i am using Cellcom Israel Sim card
i just saw the firmware update,the update run smooth but after the reboot i try'd to turn Wifi on
and getting an ERROR.
try'd to reboot the phone - wifi not working
try'd to pull out the battery and restart - wifi not working
the only thing that works is when i restart the phone in AIRPLANE MODE the wifi works
but soon as i turn the AIRPLANE MODE off the wifi disconnected and cannot turn
it on again until turn back the AIRPLANE MODE again.
i do not using any data plan connection i dont have any...
what can i do??
Just do a factory reset. That will solve this problem.
Its a known problem. Lot of people are facing it after applying OTA. Just do factory reset and you should be fine.

Factory reset doesnt do a thing bro
Hi, I had the same issue actually watch the router and say the wifi connect and then drop, i installed wifi manager and then for some reason it started working and i haven't had a issue since.
no sure why it did this but i also restarted the phone multiple times trying to get it syncing and it wouldn't until that program was installed then after i got connected i uninstalled the app and it still connects without the app
got installed "wifi manager" and again error "error enabling wifi"
Factory resetting does nothing for me, I even formatted the internal memory as well on the third time, the only way so far I have managed to turn wifi and 4g back on and also data as data seems disabled is by:
Enable aeroplane mode, restart and then enable wifi, then go to system updates and you will see the 3 options greyed out, disable aeroplane mode by holding down the power button then click on update motorola software and most of the time that has worked for me.
kc_sheets mentioned installing wifi manager, I have installed it but not restarted my phone as I've managed to get it all temporarily working and Ill test the wifi manager when I have to restart.
Let me know if anyone else can get them all working using my method.
For troubleshooting, I know dmesg is good and probably lsmod, what other linux info can help me find out what the issue it, I would not be surprised if sprint has done something to disable wifi, 4g and data as the phone starts up, but it looks like it only disables at the last minute, does anyones wifi connect as you start the phone up, I think mine may have done.
I'm hoping we can just rename the process or app that is the issue and have a non crippled phone what we paid good money for.

just flashed the phone and guess what??
wifi working again!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! w000ttttttttttttttttt
----------------------
after reboot the wifi error starts again.
that means no luck
I'm also out of the States and I just started having wifi issues today. It would see the SSID, try to obtain IP, then fail. I just set a static IP, default gateway, etc... and that did the trick.

Posted on motorolla forum:
Hey guys, same problem - briefly:
Sprint customer - overseas for the next 6 months,
1. OTA update successful, achieved over wifi
2. phone restarted, wifi connectivity lost "error" as with fisher and the rest
3. airplane mode allows wifi connection until GSM is connected again, at which point it gets knocked off
4. I /also/ fat fingered my phone during one of the restarts and had both wifi and GSM working, but it's my nature to test things, so i restarted and of course now it's gone.
5. I am not able to attempt wally's re-register with Sprint approach as I will be away from the states untill January
6. I tried the update sprint zone fix - no luck
7. I tried the disable roaming guards - same as fisher, some of them are green and grayed out, no luck
Thank you !

[Q] Problem with Simvalley SP-140

Hi
I need help with my Simvalley Sp-140, my wifi is not working. It turns on sometimes, and sometimes not. Also when i press to turn on wifi from on it goes to off. I gave factory reset but it's still not working.
I tried a lot wifi apps but with no resault.
There is no update for my phone.
Or if there is compatible rom i'll like to try it.
Android phone without wifi, useless.

[Q] WiFi Hardware Failure, need help.

Hey guys, So here's the problems. I believe my WiFi/Bluetooth hardware in the phone took a crap. I was running stock (rooted) and the wifi was starting to give me problems like tethering would not always be visible and whatnot then it just stopped working completely.
I installed CM10.1.2 along with flashing the boot.img (phone is S-On) and no help, the support thread there told me to try a sense rom and if that didn't work its most likely hardware failure... so I did (EclipticRez v8) along with installing their kernels blah blah blah same problem.
So here's what happens. The WiFi will stick on the "Turning on WiFi" so it seems like it just keeps attempting to turn it on. Occasionally it will just say error. When it is stuck on the Turning on WiFi it absolutely kills my battery. 10% an hour with the screen off in Airplane mode. When it says error my battery life is fine, but when I open any app that uses data wifi tries to turn itself on. I have tried the settings to "Never auto turn on WiFi" and it doesnt help (I think wifi needs to be off completely for that setting to help, but I cant get it to any other state but error or turning on wifi.
So obviously this is not fun at all for me or my battery. Now where I need help is if there is a way to just completely remove wifi from android. Like is there a way to just get rid of the kernel driver for wifi so It doesnt even exist on my phone?
Any other suggestions would be greatly appreciated
So if Wifi and BT don't work. Hardware then. Seems like it's starting to happen more frequently nowadays.
Same thing started happening on my wife's Rez last week. Mine is still running fine. I wiped and installed 3 different roms to establish that it is hardware related. She still isn't convinced it isn't due to me flashing new kernels, etc.

[Q] Galaxy s2 wifi issues

Hi all, the galaxy s2 I am using has always had problems with its wifi. I inherited it from my mum when she upgraded to the galaxy s4. The wifi didn't work when i got it, but did after a factory reset. The problem has come up a few times since then and has always been fixed with a factory reset.
So the problem- I can connect to the wifi, the phone says connected and has the wifi icon in the notifications bar. it says it has 3-4 bars, but the send/recieve arrows don't light up. The phone functions like it isn't connected to the wifi, even though it is. After every reset attempt the wifi comes back for about 5 minutes and then the problem starts again.
Is there any solution to this?

Random Reboots and Frustrations T_T

So recently I have been having random reboots for my s6 edge (SM-G925W8) running G925W8VLU2AOG2 stock
I am not sure whats going on but when i'm at home the phone seems to be fine when connected to wifi, bluetooth etc.
As soon as I got to my university and im listening to music with Wifi turned on I believe the phone just randomly starts restarting and I cant stop seem to stop it until the phone runs out of battery, it'll keep on rebooting. I have a theory that maybe the wifi is somehow conflicting but again im not sure. The phone works fine at home....
There seems to be too many variables at play and I have no idea how to solve this
I desperately need my phone for school and personal stuff
Troubleshooting steps I have taken
- FULL factory reset with ODIN (wiped everything)
- Tried Safe mode didnt help.
I would just to bump and update you guys that I have confirmed its the wifi causing it. Everytime i connect to my school wifi , my phone just starts rebooting randomly and just keeps going. Now the question is how do i solve this =/
