SM-G901F WiFi Pemanently Switch Off - Galaxy S 5 Q&A, Help & Troubleshooting

Hi All
I have an issue with my S5 Plus (G901F) a few days ago I rooted, TWRP and installed the stable MM ROM from Tkkg1994 and have been happily using my phone. This morning while I was opening the Gmail app the device rebooted and when it came back up I noticed WiFi was not on. Pressing the quick menu WiFi button turns it green for a second before going back to disabled. Likewise going to into settings - WFi and using the slider does not work either, it just goes back to off.
So far, I have wiped ART/Dalvik, reflashed BL and Modem, factory reset. Wiped the whole device and redid everything including diffrerent ROM's on the same BL/Modem (CPE1) and have the same result.
Everything else works, just not WiFi, I should also add I have tried with and without the SD card and disabling/enabling other radios (GPS/BT) in different combos has not worked either.
Has anyone come across this and can they suggest next steps?
I'm currently downloading the stock ROM that came with my phone to see if that helps.
Cheers

Stock ROM did not help.

Did you find solution? I have recently started to have same issue with same device.

Probably not. The S5 seems to suffer a lot by such issues. I bought mine 3 months ago in a shop. It worked for about 2 months very well. Then all of the sudden it became hot in my pocket so i had to quickly remove the battery. After this the device suffered by ocessional reboots. Nothing helped. Even trying to reflash the stock firmware by trying several Pit´s.
Finally got a replacement as obviously either the RAM or the CPU got defective. The other phone lasted for one week as the wifi module got defective there. Nothing helped either. Now it´s my 3th S5. This weekend my flashlight and camera stopped working. Fortunally got this fixed by reflashing the stock firmware.
Honestly I like the phone but it seems to be quite buggy. Never got such problems with my old S4 and am thinking about going back to the older device.

dude try flashing 4 files flash through odin

Atrix keeps crashing (wifi?)

I have an ATT Atrix with 4.5.91. A couple of days ago, the Atrix started crashing 10+ times per day. It always happens if I try to turn on wifi, but happens other times too. Sometimes wifi will show error, instead of turning on. Bluetooth has been spotty as well. Any ideas? I tried reflashing 4.5.91 already.
Did you flash any ROMs? Kernels? Is phone unlocked?
Please, give more info....

Have you recently installed any apps that are using internet connection?
Install one of the firewall apps for android and monitor what's happening when you turn on the wifi.
It is unlocked with the 4.5.91 pudding + preroot sbf. I had the upgrade.zip version on it when I started experiencing the problem. I then flashed it with the 4.5.91 mentioned above to see if that would fix the issue. I have not installed any new apps recently, but some could have updated I suppose.
Just out of curiousity.. what Radio are you using?
I have never flashed the radio specifically. My baseband version is N_01.77.30P.-
I am also having this problem. I currently have stock 2.3.4 on ATT and my baseband version is N_01.77.30P. I've never rooted or unlocked my Atrix, all stock.
When I am able to turn wifi on, it will sometimes connect but only for a few seconds. Then it just reboots multiple times. If I am able to get it running, it says error by the turn on wifi option under settings. Mobile hotspot doesn't work either. If I keep wifi off, it doesn't crash.
I've tried restoring to factory settings, both through the factory data reset while the phone is on and through android recovery, but neither help. Any other ideas?
thanks
Backup your current rom. Flash stock 2.3.4 via fastboot. Wipe via fastboot. Reboot. --> problem solved

I tried that. The issue persists. I am thinking it might be hardware based.
Absolutely the same Wifi problem for me.
I'm on stock 2.2, rooted and deodexed.
Never has any wifi issues previously. And it's started for no reason.
Last program i installed was Tunein Radio and it worked fine about a day with Wifi. Not sure it's related.
Tried to restore my old cwr backup, but it's not helped.
A friend of mine had this problem with his atrix. His was stock ATT firmware never modded or unlocked. I factory reset it and problems persisted. His wouldn't connect to wifi at all. I believe it was hardware related, so if you didn't void your warranty, return it. If you did, you can ask Motorola to fix it... see what happens.
Side note: I kept the malfunctioning phone away from my functioning phone as I did not want it to get any ideas.

This happening to me now. Still no solution for this? My atrix:
System version: 4.5.91.MB860.ATT.en.US
Android version: 2.3.4
Baseband version: N_01.77.30P
Kernel version: [email protected] #2
Build number: 4.5.91
If I set the IPaddress, it wont connect. If I left the IPaddress blank, it automatically set to 192.168.1.253
Help please, thanks.
(FIX): go to wireless settings go into advanced settings. Click on sleep settings chose NEVER! Problem solved! Try it works

If I were you, I would contact at&t and see if you're still under warranty (by default motorola gives you a 1 year warranty). I have had the same shutting down issue with 3 atrixes. my 4th one is actually in the mail and should be here today (wooo... kinda). I also believe that the atrix has a very bad issue with hardware. Ive tried tons of rom, stock and others such as cyanogen, and this issue persist no matter what software you run.
I've had issues with WIFI/Radio causing regular crashing, especially when trying to switch to Airplane mode. I'm running CM7 (stable) and 77.36 radio. I've been able to resolve the problem by booting into CWM and reflashing both CM7 and the radio. Sometimes I have to reflash the radio a couple of times. Eventually it seems to take and then the Atrix is quite stable.
For me, the instability problem occurs whenever I reset the battery stats. After I perform the steps above, it seems to resolve it.
Anyway, if you're running stock, I'd recommend downloading a copy of the radio you're using and try reflashing it a couple of times via CWM before you give up on the phone.
I had the same problem. Returned mine under warranty. They told me that just the day before me they had someone come in with the same problem..
Well... started having this issue recently myself, not too sure exactly what had caused it. I had been flashing a few of NFHimself's Gobstopper's, after my phone took a nose dive (one of the screen shattering, battery flying and denting variety) and I started getting reboots. I hadn't had a chance to play with it prior to the nose dive, but I do know that I had reset the battery stats (something I DON'T normally do when flashing) so I'm hoping I can replicate the fix of radio flashing.
Right now I'm going to keep re-flashing ROM's and Radio's, so far just trying the Gobstoppers 2.2.2 and upwards as well as samcripp's Fruitcakes and this radio, I'll be sure to update if this works. Pretty sure I've voided my warranty a few times over already (unlocking, plus the shattered screen kinda shows signs of abuse) so returning isn't exactly my first idea.
I'm guessing that it would seem to be related to this battery stats issue, as my GPS seems to be working and I'm fairly certain that it is the same chip that controls GPS, WiFi, and Bluetooth. So unless it's some very specific hardware based issue, this is my best guess.
If anyone is aware of any other potential solutions to this issue, or knows of any other Bell Mobility (Canada) radios/ROM's, I'll be more than happy to try your suggestions!
I had a similar issue. My phone would crash multiple times a day. It started after att released an update. I read somewhere that it could be an app causing it so I went into taskmanager and had all apps end after use with the exclusion of pandora and navigation. Problem solved. Not sure what app was causing it but I never had a single crash/random reboot after. Phone was unhacked and the only update on it was the last official one released by att (sorry can't remember the number. I've since upgraded to a Cm7 rom).

Problem with touchscreen since 4.4.2 update

Hey there
A friend of mine has the following problem with his Note 3 (completely stock).
Since the latest 4.4.2 OTA update, sometimes suddenly the screen does not respond to touching it with your hand. It does react to the stylus.
Locking and unlocking the screen does the job, but only for a few minutes.
I wiped the phone via stock recovery, but the problem persists.
Anyone with the same problem, or maybe a clue?
Thanks!

Hi
Same problem here,I tried several 4.4.2 official and custom roms but not fixed and I tried these too:
I tried mega wipe and last rom in samfirmware!
I removed my external sd card
And I googled and found there are others with same problem so it shouldn't be hardware problem
p.s.When screen freezes just half of it works! And just doesn't work by fingers and it works by s_pen!
There no way to come back to 4.3 too
What should I do?
Ty in advance
Finally Solved!

I did everything u said like:
mega wipe and changing rom
custom roms
taking out battery when it's on ( I Did this but I don't know It had any effects on my phone or not!)

Solution:
But I had a flip cover and I separated that from phone and thanks God,surprisingly It's Fixed and it works like a charm!!! after that I used my original cover and there is no problem till now.
Good Luck
Had the same issue posted it here bit no one responded.
Solution: The flip case I had..there's a problem with it where it locks the screen even when the case is not closed. But lately I had no issue it just seem to gotten fixed by itself.

[Q] Why does my Wifi & Bluetooth not working even with stock rom?

Hey guys,
I have a Galaxy S4 (i9500). I installed Omega ROM v22 on it and everything went smoothly, Wifi & BT working perfectly.
After a few hours of using the device (nothing special at all, texts and stuff like that) - I noticed my wifi isn't working and by not working I mean that I click the wi-fi button and it changes from gray to the mid-state between gray to green for around 20 seconds before it goes back to green ago.
If I open the menu to see my networks it just says "Enabling" without any networks there.
I had to drive somewhere so I went to my car and tried to enable Bluetooth, and same thing happens there - Bluetooth will not turn on and will stay stuck on mid-state between gray and green for a while and go back to green.
I flashed omega rom v22 again and the problem was gone, or so I thought. I went back to the car for another drive and realized the bluetooth issue is back - and when I got home I realized the wifi issue is back as well.
I figured I need to reset everything so I tried the following:
Full wipe (including dalvik and even including "internal SD card") and then flashing stock rom (from the official website, stock rom of my country).
The issue was back after a few hours. I do not have BT or Wifi access. Yesterday Wifi suddenly started working for a few hours but then it stopped working again.
I really need help! I have no idea what to do with this issue!
Well rule number one when you have problems after flashing without wipe.
1. perform a full wipe and see if the problem persists.

Tried that, no luck.
What else would you try?
In some places when people had problems with Wi-Fi they said to flash a different kernel but I don't see why I would have this specific issue with Omega Rom and why the default kernel with it wont work well?
Maybe this could be a root issue? My root works fine but I have this weird gut feeling like this is some permissions thing that's going on.
I'm trying to think why it would work right after the wipe but then stop working shortly after.
Another symptom: It randomly started working for a few minutes and then stopped again (around three hours ago).
Any idea what's going on?
Well, if you fully wiped and didn't restore any apps and settings then it can be two other things.
Or it's a bug in the rom or a hardware failure in your phone.
I would suggest trying a different rom first. Do not restore anything, not even your google account.
wi-fi fix?
Do you actually have an i9505? or is it a canadian or att version? if its the latter sometimes the devs offer some wifi-fixes, also try a different kernel. otherwise it could be that your radio/modem are not compatible with the version of the ROM you are flashing.
Tried arrow ROM and this issue doesn't seem to happen in this rom. Hope it stays like that...

Sadly, it did happen with this rom, after just a few hours.
I'm now using stock rom and still suffering from the issue.
Does anyone have ANY idea what I can do to fix this?
Thanks in advance!

Galaxy S4 doesn't work properly anymore.

To preface the current issue with my phone, I guess I should probably give some history of what I've done to it. I got my S4 around November last year, where I kept TouchWiz for about a good 3 months. At the end of those 3 months, I downloaded and installed CM KitKat using their easy installer and it worked! However, when Lollipop came around, I got a little impatient and decided to get CM12 using Antares version. Initially, I noticed there were a few bugs/glitches, but ignored them for the time being. As time went on, it became increasingly aggravating and so a few dayus ago I tried to switch back to stock TouchWiz. When I was setting up the phone, I noticed that the wi-fi would just not turn it. It would stay at "turning on" for a very long time with no sucess. Thus, I decided to switch back to Antares version of CM, but now there were a few issues: service was VERY spotty and the piece de resistance: no sound at ALL, and youtube would never play videos. I searched around and saw that using the Sound Recorder would give me an error: "Internal Application Error. Microphone may be in use." Now I'm not the most techy person around and probably should not have been messing around with my phone, but now all I want is a properly working phone, doesn't matter if its kitkat or lollipop. Your help is greatly appreciated. (If you need to know more info, go ahead and ask, because I'm very new to all this) Thanks!
If you want the stock ROM back, flash it twice using Odin. General consensus here is that you need to flash the modem twice in order for WiFi and cellular radios to work properly. Flashing the ROM twice will do that without having to track down just the modem file and trying to flash that.

Unfortunately, it doesn't seem to be working :/ When setting up my S4, it's still stuck at turning on the wifi
I switched back to Antares CM, and everything works fine except for sound/microphone (to my knowledge). Would there be any way to fix this?

My OnePlus2 seems to break more and more in software :/

Before some weeks ive been asking here what ROM I should use. Ive done this cause my power drains to fast.
So I switched back to OxygenOS3.0 and everything worked fine until today.
Today my phone got always authentification problems with my WiFi at Home.
So ive thought to fully unroot my device and go back on the first stock ROM.
But it fixed nothing and I also restart my router so thats not the fault.
Also the Fingerprint Sensor including the Touch Function doesnt work anymore ive also got this problem before a half year but fixed it very fast after installing CM13.
Now ive wanted to know if someone got the same problems or one of them and could help or give some advices the phone is only 1 year old and I didnt want to swap to another one until a year.
​
What I would do is flash some other roms and make sure that you're using the hybrid twrp
Or probably start over again after flashing stock ROM.
Before that try clearing cache and Dalvik which solves issues on most deodexed ROMs.
