Stuck on "turning WiFi on"

Two days ago I turned off my GNex and as I turned it on and tried to turn on the WiFi, it get stuck with the writing "turning WiFi on" and the WiFi "button" blocked (I can't turn it neither off nor on).
I tried to reboot several times but the phone is stuck with this problem since the moment I turn it on.
I never modded anything with my Gnex, never changed ROM or kernel, so I found this problem quite strange.
Does anyone knows how to solve this issue?
Thanks in advance

so i assume you are completely stock. hard reset should fix the issue. i have seen this before on other phones and the hard reset seems to fix the issue.

Check the system logs i.e. 'logcat', 'kmsg' to check if something's wrong with the hardware.

Your next step, if factory reset doesn't solve it, is to reflash factory images. It will wipe your device's entire memory. Step-by-step instructions here.

I'll try to flash a factory image asap, thanks

Wifi switch Grayed out
My Sprint Galaxy Nexus is presently on 4.2.1 and has been facing wifi issues. The Wifi button/switch/toggle under the settings options has "Grayed OUT" and wouldn't allow me "ON it".
This happened after I downloaded an app from google play. However after which i removed the same by unistalling it and have been facing this wifi issue since then.
I did a Factory Reset but WIFI remains "Grayed OUT". Can some one guide me to solve this issue.
Thx in Advance

Just read the thread (and linked threads). The troubleshooting steps are the same for you. No need to hijack the thread (you didn't even mention which app that was, for example, you only need to press thanks and follow our lead).
P.S: I honestly don't care if anyone presses thanks or not.

I just brought it to the assistance and they changed the wifi module

That's good, glad to hear it. Have you grabbed the logs from kernel/system, back when it was not working?
If you did get them, now we have a "template" of what the kernel and system report when it finds this kind of failure.

[Q] wifi bug?

Obviously i have the ascend P6-U06,
the main problem was the WIFI connection, WIFI is sometimes blocking,showing the icon but it has no connection, to activate it i need to go into airplane mode, wait 5 seconds, then switch to normal again. Only then i have a good WIFI connection. but i have to repeat this every time the phone comes out of sleep mode.
I have done several updates en upgrades. but nothing seems to work. I tried B112 firmware and the B510 and B512. recently upgrade from android 4.2.2 to 4.4.2, first with B634 firmware and now B635.
Still the same problem, Does anyone have a solution for this.
Thanks in advance !!

This is somewhat dissapointing. I was hoping that someone had a solution
Mayby i can install en new (more stable ROM) ???
i don't know if that would be the (a?) solution.
Anyone an idea??

Try installing CM 11 with full wipe on the phone.

WIFI will not turn on

Hi guys i have a lg g3 that has been running fine on kitkat
it the received the lollipop update OTA and all went fine apart from now it wont turn the WiFi on
you can click it on and it moves to on but seems to be always trying to turn on..?? without turning on.?
any ideas..?
I have done a reset etc still no joy

Did you try to reflash? (I think that you mean by resetting that you full wiped your phone and not reflashed the rom)

Same issue here.
I get around it by forgetting network then just signing in again. Wifi works perfectly until I leave the house and return later. Then I just do the above and viola, working wifi.
I've checked with speed test app and wifi is definitely working.
Funny thing is, if I switch off wifi then turn back on it also works.
Only when ive left home and returned later does this bug arise.

Hello guys,
This thread is a little bit old, but I am curious to know if you found a workaround for this issue.
I have the same problem as the OP (not at the second poster): since I received Stock Lollipop the WiFi won't turn on. When I try to, it says "turning on" for a while then acts like it is off.
I just bought my LG G3, NCIX the reseller, refuses to refund me or replace my phone...
I performed several factory resets and tried to flash different KK stock Roms. The weird thing is that the WiFi works with KK...
Thanks for your help.

Identical experience here.
I recently got a D855 16GB, which was on stock unbranded V10a, jumped through several OTA updates through V10g, V10j, and V10k (IIRC) all with wifi working fine before getting the lollipop upgrade OTA for V20c.
Immediately wifi will not switch on - the switch itself is on, but with the off section a lighter grey compared to the bluetooth switch.
On the wifi screen itself it says "Turning Wi-Fi on..." but after a while the switch reverts to off.
It's now had OTAs to V20e and V20h, but wifi is dead on both versions.
Note that this is stock and unrooted (never rooted) so I can't believe it's something I've done. Next trick will be to root and poke around /data/misc/wifi.

Does bluetooth work or the problem is only with the wifi? I also have the same problem, wifi, bluetooth is not working and when I check in the settings the mac adress it says "unknown".

Accountability
Unfortunately this isn't a unique problem. There have been countless bad updates from multiple manufacturers. In this litigious world, I'm surprised no one has sought damages for bad updates that effect usability.

I have the same problem from yesterday. wifi and bluetooth seem to be turning on but they never turn on. i've done many factory resets but it didn't work. has someone found a solution?

^^^ Exactly the same issue. Would love a solution!
Same issue. Tried Hard and soft reset and have also updated firmware using LG Mobile Support Tool but had no success.

ok, after 24h with this problem I think I got it back to working. Let me explain what have I done:
1. Mine is a dual sim model, that I bought in hong kong by the end of 2014.
2. Yesterday, I removed sim #2 (no longer needed), without removing the battery. I had a couple of messages indicating to restart the phone, blah blah. Can't remember if I finally restarted it or not.
3. This morning I saw no wifi connection in my phone, only 3G. Tried to start wifi in the quick access menu, but this kept blinking, never starting wifi. Restarting phone... nothing. turning off bluetooth... nothing.
I figured out that the problem had to be related with the SIM as this is the last thing I had done with the phone. Thus, I tried this, with success:
4. I turned off the phone, changed sim from slot #1 to slot#2 and started the phone. Wow, it worked for some minutes, then stopped, then started again. Well, a good sign.
5. Changed again sim from slot #2 to slot #1: Wifi working again. After some time it stopped working, but soon started again. Hasn't given me more problems (after only 30 min, that's true).
Hope it helps.

Got the same problem here. I have my G3 since november 2014 and recently I rooted it to install CM 13 on it and Xposed bcs I got tired of the laggy software of LG. One morning I woke up to drink some water and saw my phone restarting a lot of time... ok I thought its a simple bootloop. Tried to install CM again, didnt fix it. Flashed stock software and still... Bought new battery and new power flex and the problem is still there. I go into download mode, installed the software with LGs support tool and got pass the bootloop, but now wifi nor bluetooth works. I thought it's the software so I dared myself again to root it and installed TWRP and CM13, but it wouldn't boot. I installed then Liquidsmooth, based on CM13, and got it to boot up, but in the configuration menu where WiFi is needed to be added it couldn't turn on. I skiped it and in the middle of the process it started again to restart. I don't know if it's a hardware based problem or software... But I would like to try everything out before I have to buy a new phone.

I installed CM13 and in the setup screen I actually had wifi and I could connect to my router. It was kinda strange. But bcs I have some problems beside wifi, the reboot thing, I couldn't test out if it works too. Try flashing CM13 or ROMs that are based on it like Liquidsmooth. Maybe it will help.

Unable to start Wifi & Bluetooth

My LG G3 wifi & bluetooth stucked at turning on. Tried factory reset, flashed the ROM & use FXR wifi fix and rescue but still not working. Have not tried changing to another Kernel yet. Could it be hardware problem?

I don't think so... Maybe an app is in conflict with wifi & bt.

Similar issue on my end - About a month ago, I opened a support ticket with LG. They returned as "repaired" and my phone worked for about three days before the issue returned.
Using Titanium Backup, I restored the bluetooth system software and it worked for about a day. Considering flashing my phone back to stock and starting over.
If anyone has experience on finding a permanent fix to this issue, I'd be all ears.

Try booting into safe mode and see

I'd be very interested in a fix for this too.
I've a completely stock unrooted D855 that last week seemed to over heat and shut itself down. On restarting it's eaten it's way through the battery in very short order, gotten hot and shut down again. Rince and repeat a couple of times. I've then factory reset and its continued to do the same thing.
Further investigation has shown the WiFi and Bluetooth "turning on" constantly without ever actually turning on. And I've then discovered that the MAC address (and Bluetooth equivalent) are missing.
Would appreciate any help possible

Seems like i'm not alone. Yup my phone auto restarted few days ago after turning on wifi & it keep rebooting if the wifi is turned on. Only stable after i flash the ROM but the WiFi & Bluetooth issue persists. Safe mode does not help.

Same issue started 2 weeks ago. Factory reset didn't fix and battery life being killed by constant searching for BT and wifi. Unlocked G3. Waiting for Marshmallow in the hope it fixes it.

You could also have broken firmware when i got my g3 wifi turned on and off and always dropped connections i ended up reflashing stock with flash tool and tot method and it fixxed i had a bad firmware download straight from lg

hmm so no one has a way to fix this issue?

On 4.4.4 = boot loop, and for android 5 battery drain and wifi bluetooth issues.
Waiting for marshmallow

i found a post by someone else in another forum that fixed this problem. I followed some of his steps to reboot into safe mode to turn off the bluetooth & wifi but it didn't work so i turn on Airplane mode while i'm on safe mode & reboot again in safe mode & it works.

Any fixes with Marshmallow ?

Would be good to know a fix as recently happened to me. Can now only use data for Internet and am getting through a battery in 3 and a half hours as the phone is constantly trying to connect the WiFi and BT. Tried Factory reset. Used LG Mobile Support to update software. Now finally have the lovely Marshmallow but the issue remains. Please help!

Has anyone found a solution to this problem?

Anyone found anything on it?

New Battery
Hey everyone, I had the same problem. After installing an OTA update, my D850 crashed. When it started up again, I had no WiFi/BT. I tried several factory resets, flashing multiple custom roms, tried unrooting and returning to stock. Was convinced it was a hardware problem. As a hail mary, I ordered a new battery off Amazon. I put the replacement battery in my phone, and WiFi and Bluetooth are now fully functional. Is it possible that everyone with this problem just has a bad battery? It's definitely worth a shot.

probably a hardware issue...
Hey guys,

Can't turn on WiFi

Hi guys, I have discovered an issue few days before. My WiFi don't became on when I turn on the screen. Same as if I want to turn it on manually, the switcher in settings came back to off position itself again and again. But after few try it stayed in on position - but only sometimes. Sometimes I have to reboot phone to get working wifi, immediately after reboot it working without issue. Maybe it have something to do with deep sleep.
I have tried reflash the ROM(leedroid), kernel, uninstall Magisk and now even restore stock TWR backup. But problem is still here. I'm S-ON and don't know what I can try next.

Is there the possibility that the Wi-Fi module of the phone itself (hardware) is acting up ? Just thinking out loud for a bit......

I don't know how to verify it. But I'm not alone who have this issue acording to LeeDroid thread. But I think it must be software issue. If try to switching it on again and again, after few try it generaly turn on the wifi.. From the other end, when wifi working and I turn screen off, wait a few minutes and turn it on, wifi is still running. I have the option that turning on wifi in sleep mode..

It's very strange that just a handful of the complete user base is having this issue. You also restored your stock rom so it's not a leedroid thing for sure, it's also not a mismatch firmware/software (because it's happening on stock software too)
I'm running out of ideas to be honest

Mine even bluetooth stopped too. But I will try flashing official rom and see if that helps.

I've had the opposite problem where my wifi won't turn off unless I reboot it.
I'm about done with this phone. WiFi has always been crap, and phone still reboots randomly several times a day, despite going to Oreo from a clean RUU and trying a couple different ROMs (Maximus and LeeDroid).
Sad thing is, my M8 is still kicking and is bulletproof. My son puts that thru the works and it can't be killed.

I have same problem. In WiFi settings, I always set Keep WiFi on during sleep to 'never'. After I did something with radio settings using dialer code *#*#4636*#*#, I have started facing this issue. For now, I set that setting to 'Always'. I don't know if resetting phone will fix it. I'm using official software from HTC.

I will going to downgrade to Nougat and try it on Nougat firmware with the guide I posted bellow as I'm S-On. Hoping that I not ended up with bricked phone
https://forum.xda-developers.com/htc-10/how-to/how-to-rollback-oreo-to-marshmallow-s-t3787101

Hi guys, let me inform you that I'm o Nougat now and my WiFi problem is gone, it working without issue! So it is not a hardware problem and it has nothing to do with ROM or Kernel. It is something in Oreo (or firmware) what causing this. Maybe there is a problem in OTA to Oreo, who knows. I will take the OTA (by official way) to Oreo later this week and we will see

I'm still on Leedroid Oreo, I turned off button light notifications and volume button tweaks and I have not had the wifi problem since.

Those are totally not related to each other, code and settings don't come near Wi-Fi actions. BLN is btw a kernel tweak, volume buttons a rom tweak. I bet my life on it that its something else.
And to ensure you, i use the same tweaks. All fine on my end.

I have tried take OTA by official way = WiFi issue on Oreo
I have tried install OTA from recovery = WiFi issue on Oreo
I have tried install Oreo RUU after OTA to Oreo = WiFi issue on Oreo
But everytime when I downgrade to Nougat, WiFi wokrs like a charm..
Anyone have idea what I can try next? I think that issue is in the Oreo update

Ah oké, i installed the 2.41 ruu and updated via OTA. My Wi-Fi is always on. I'm not using the option to turn it off when the phone sleeps.
Full setup

- Basic leedroid rom
- Root via SU (no magisk for me)
No modifications whatsoever.

So u updated by the official way as me (setup is same for me). Interesting. Can you try turn on the option which turn off wifi when phone sleep (only without charger) and test it for day or two? Watch on your wifi when You wake up your phone..
It might be enough if you turn it on when you go sleep and watch wifi in the morning when you wake up your phone. And your phone have to unplaged from charger over night..

Sure, will start testing it after work. will report back tomorrow.

Also maybe good to mention is that i am using a 5ghz network. I put the option that my Wi-Fi always go to sleep. Let's see what happens til tomorrow

I wonder if turning wifi scanning off, in location settings, is also a trigger. I think I didn't have any issues with it, then yesterday I turned wifi scanning off and today my wifi toggle didn't work and I had to reboot my phone to ge it back.
