LG G2 WiFi stuck to "Turning On" - G2 Q&A, Help & Troubleshooting

Hello All,
I have upgraded LG G2 to
LP 5.0.2
BB : M8974A-AAAANAZM-1.0.190128
Kernel : 3.4.0
Build : LRX22g
Software Version : v30-eur-xx
i am facing consistent WiFi issue after switching on it gets stuck at Wifi Turning on but does not connect.
It has got an MAC address. sometimes very rarely it may connect to WiFi but then disconnects after 3-4 minutes.
I have tried clear cache, factory reset but problem still there, has anyone faced similar issue and can help me here
many thanks

Did you have a problem before upgrading? If not, then it's unlikely to be a hardware issue and something could have gotten messed up in the update process.
If I were you, I would TOT back to KK following THIS GUIDE. After it installs, do a factory reset. After it restarts, then update to the latest ota and factory reset once more. That will get you a clean install as possible.
Btw, have you tried connecting to another wifi access point? Sometimes networks can be setup incorrectly(ie two routers with dhcp enabled on one network) which can cause problems.

Hello Stan54, I rooted my LG G2 last year and was on Kitkat, phone was running fine since that, in December I installed nova launcher and couple of other applications but not able to find the log. After that I started having this issue. One peculiar thing is it can start it's hotspot correctly and I can connect my PC to phone's hotspot WiFi SSID and bluetooth is fine as well but only Wifi keeps stuck at "Turning on" mode.
Since then i have
1. Flashed it to stock JB ROM {Using LG Flash tool}
2. Upgraded to LP5.0.2 using LG PC Suite
still the issue remains
one slight improvement I saw after that is
1. It connects to WiFi for a minute or 2 then goes to "Turning Wifi on" mode
I will try to go back to KK and follow steps as suggested and update.
thanks
Edit : I have tried connecting to other WiFi networks as well, same issue.

[Q] My samsung galaxy s4 won't remember my wifi network

Okay so I have a Samsung Galaxy S4 from sprint, I love the phone it’s great. I was on the mdl update stock rooted and everything was working fine with wifi. Then I did a factory reset updated to mf9 (the latest update) and then rooted it still stock. Now my phone will connect to wifi if I manually connect to it and works fine, however, if I disable and reenable wifi or restart the phone or leave my house and come back, it will not reconnect to my network automatically, I have to select it myself and put the security key in everytime. When I disable and reenable my wifi it will show “secured” under my network, making it seem as if it never tried to save the network in the first place, So it won't automatically connect like it use to on the mdl update, because it seems as if it forgets it when it disconnects.
I tried even connecting and then forgetting the network and then connecting again to see if that would fix it but it didn’t.
The weird thing is that at my work it remembered the network and connects automatically and when I’m in range. And when I’m away from work I can see it saying “not in range”. Why isn’t my home network doing the same thing, and how do I fix this? (btw I really don’t want to do another factory reset if I don’t have to.)
-I have a 2wire 3800HGV-B router.

Okay well I fixed it by unrooting and using odin to go back two updates prior to mf9, then did 2 ota's back to mf9 and rooted again. all is working fine, also fixed the phone's getting too hot problem and battery last longer than ever.
it's your kernel that was causing this...for future reference, if you're on mf9 with the stock mf9 kernel and do not want to have to wipe your phone to fix this, you can use ShabbyPenguin's kernel...i had this issue before on my s4 and this worked for me...why the rooted stock rom doesnt like the stock kernel for wifi blows my mind...lol
How was it going on? Do you still have the problem with the wifi?
Perhaps you can try this: http://forum.xda-developers.com/show...56&postcount=2 (Greatly appreciated and high credit to dajumper's work.)
This works on my I337 NI1 Unlocked Rooted. I uses ES Explorer with Root Explorer enabled.
I went to the "system " folder in the device, scrolled down until I found "build prop" then edited using ES Explorer Note Editor.

Nexus 4 wifi troubles after upgrade to 4.4.2

Hey guys,
I am having trouble connecting to wifi after I upgraded to 4.4.2.
When I leave the house my phone shows its still connected to my home network, or if I connect to a network and return home, it shows I am still connected to that previous network. Also when I return home I am unable to connect to my home network until I reboot my phone.
Wifi optimize is off, wifi idle on sleep is off... I am not sure what else it could be. Any suggestions? I use my phone for voip over wifi (csipsimple) so this is extremely frustrating !
Thanks
Was this a OTA update? Are you running the latest radio? Did you try a factory reset?

my phone was rooted, so i could not install the OTA update. I tried many ways to update it without wiping the data over the phone but it would not boot. In the end I had to wipe the phone and flash the image from the google website (manually flash, bootloader, radio, image and all). Lost all my pictures .
I used the image from : developers - google - com - Android 4.4.2 (KOT49H)
BUMP^ any ideas what I can do to fix this?
After flashing to 4.4.2, does the baseband end in .97 or .98?

Wifi and bluetooth malfunction

I have a p8 lite. A couple of days ago it froze and i had to press the power button for a few seconds to reboot it. After that the wifi and bluetooth are not turning on. It was working fone before that. It just locked tge bootloader and rooted it after this. Do you guys think i can try flashing another rom on it to see if its a software issue. Can i get the baseband or radio for it so i can flash that?
Formwaee is b130
Its a dual sim phone ale l21
Your help is appreciated.
I am also having the same issue. The phone shutdown and when i turned it back on the wifi/bluetooth stopped working. Wifi can be switched on scans for available network but cannot see any, though my other devices are connected to the same router. There is another P8 Lite phone connected. Router has been rebooted and reset. Same thing happens to BT it wont see other BT enabled devices and other phones cant see the device. I have already rebooted the phone, checked wifi settings, Wipe Cache Partition several times and even did a Factory Reset but it didn't seem to help.

Boot into recovery (while turnig on your phone hold power + vol- + vol+), and wipe cache. It solved for me.

Yes, there is a fix available for the »»» Huawei P8 Lite ««« :
I have the same problem with the WIFI & BLUETOOTH: Both wifi & bluetooth buttons are gray and disabled.
This issue happened after an update from » Android 5.0 | EMUI 3.x « to » Android 6.0 | EMUI 4.0 « .
I researched a lot on the internet and found one useful information:
It is not a software issue - it is a hardware issue.
The best way to fix this ridiculous bug is simply to look for » Huawei Customer Service « so they can change/repair (or anything else they do) your hardware.
This is what i am gonna do the next days.
I hope this information was helpful somehow!

Hi, for me it solved with disabling only bluetooth search. :good:
I have my P8 Lite (2015) updated with original B634, only with bootloade unlocked.
The mobile phone is guaranteed by Huawei until 22/10/2019 (marketing bid in October 2017).
However, in recent days, I'm having difficulties in the speed of wifi (does not exceed 10k / s) when I have the bluetooth activated (for example when I arrive at my house and came with mobile phone connected to the bluetooth of the car).
If I turn off the bluetooth the speed of the wifi normalizes immediately!
Is it a software problem and a reset resolves or will it be a hardware problem to be solved under warranty?
Thank you for your opinion.
its hardware issue,just applied from my mobile operater,in Serbia
this issure is still on update? or they already fix the bug
SOLUTION!
In a Spanish forum I saw that they had solved this problem by installing the ALE-L21C432B564!
I tried but it did not work for me!
Then I remembered to do something I had not done yet!
I reset the factory settings with deletion of internal storage data, installed the rom ALE-L21C432B574 by fastboot (look for link FlashRom B574 Dual Sim).
Surprise!!!
Wifi worked at full speed, even with bluetooth on!
Then I installed the ALE-L21C432B636 by the native mode (dload - UPDATE.APP - off - start with the 3 buttons pressed)...
It is updated and with the problem of wifi + BT resolved.
NEW SOLUTION!
I found the reason for the Wi-Fi problem too slow (or stopping) when Bluetooth is turned on!
The problem is "Your location" from Google Play Services!!!
Until version 11.6.73 (14-09-2017) there is no problem, but from that version, more precisely 11.7.41 (05-10-2017), until today (12.8.74), and in the next versions (13.2 .77 beta), the problem persists.
Will Google solve the problem?
I do not know.
But to solve the problem I found this solution:
Disable GPS-Then go to Settings-Apps-Google Play services-Permissions-Your Location-Location Settings-Disable Access to my location.
From there, you may already have Bluetooth enabled and Wi-Fi will work properly.
However, if you also activate GPS (wf + bt + gps), the Wi-Fi will be very slow again, until you deactivate the GPS again.
It seems that some equipment does not have this problem! If so, good for them, but for those who have this problem, the real reason is already found, and until they solve it (if they solve), we have this solution.
I'm grateful that you also report this error to Google, to see if they fix it.

WIFI problems

Hi,
I open this thread because I detected this issue after doing a downgrade of the STOCK ROM.
- After apply the OTA for NPNS25-137-33-11 (RETEU) and return to NPNS25-137-33-5 I start to see very annoying troubles. Sometimes, when the WIFI state changes (mainly when stating it, or enable hotspot mode, or chaging from one to other network) in this case the phone hangs. The only solution is a hard power-off. Also I noticed that the WIFI range is very small.
I listen before that some users have troubles with WIFI. I haven't detected any problem before, only now. My assumption is that the OTA has updated some partition with RADIO data. Then, now the driver is unstable.
Perhaps some others have a similar problem because an upgrade using a flash backup and not upgrading their RADIO partitions.
Please, share your experiences to see if the problem is widespread?
Thank you!

No wifi on stock ROM and MAC address reads 02:00:00:00:00:00

My G4's been working fine since i had but about a week ago i noticed it wasn't connecting to any wifi networks. It was searching but couldn't find any.
I did a hard reset and now can't get past the android set up page, as soon as it starts searching for a wifi network it locks up and then reboots after about 10 seconds.
The MAC address is listed as 02:00:00:00:00:00
I've reflashed the Stock ROM that was already on it but it's made no difference,any ideas???
Have you got root?
No never been rooted
You could try rooting your phone and changing manually the MAC with some app.
Can't get past the android setup so I can't install any apps!
Give more detailed info about your problem
Bootloader unlocked or not
before flashing on whick rom you were?
What flashing instructions you used and what guide you followed?

The bootloader isn't unlocked.
Before flashing it was on NPJS25.93-14-13/3
I reflashed using https://forum.xda-developers.com/moto-g4-plus/how-to/stock-rom-npjs25-93-14-4-march-1-t3608138
Just to clarify the wifi wasnt working before the flash hence the reason for reflashing
Just tried unlocking the bootloader so i can try other roms but it wont let me. Keeps telling me to tick allow oem unlock. Cant do that as i cant get past set up screen!!
are you sure you are flashing the right version for your device??? flashing wrong firmware causes the MAC id issue most of the time!

Yes definitely the right version. The MAC id problem was there before any flashing was done.
at setup screen skip the setup, if you can. I am not sure, if you can skip it or not..I don't know, what other way you can do things without unlocking the bootloader
There's no option to skip the setup unfortunately, It locks up and restarts once its trying to connect to wifi. I've tried using the mobile network but it still crashes and restarts (I'm assuming that this is because wifi is still being turned on).
I'm at a bit of a loss what to do really???
I'm not sure whats causing the issue with the wifi,flashing stock ROM hasn't helped and i'm unable to unlock the bootloader because i can't get it to boot! Any help greatly appreciated!!!
Im beginning to think that there's no way to fix this,what i can't understand is why the wifi still isn't working after reflashing stock ROM surely that should clear everything back to factory including whatevers stopping the wifi working.
Could possibly be a hardware issuei suppose ,is it possible to replace the wifi chip?

I still have the original stock rom and exactly the same problem!
The last update ****ed it over!
I will now try cache clear on stock rom before I go further
Edit - No change! Definately need a solution for this
As I have the same problem I will wait for further support so that worst case I can provide help for the other user.
Mobile Data still works tough
Phone: never rooted, after cache clear it doesnt ask for update anymore which helps
EDIT 2: Got it to work. I wsa able to get into a public wifi download the new update and all is fine.
1. Clear cache
2. public wifi or download the latest update from XDA and start manually
This should fix it!
Just to share what helped me to recover Wi-Fi and solve the MAC address 02:00:00:00:00:00:
A. Get the apk file of the Wifi Mac Changer app and install it in your phone without Wi-Fi.
B. Open it and grant root access. You'll see that your "Real" MAC address will be 02:00:00:00:00:00.
C. Then you have your "Fake" Mac Address. Copy it into the line "New Mac" and press "Hard change" button. You don't need even to reboot to restore your Wi-Fi.
D. For me, it worked at the first time, I can also uninstall the app later. Later dirty flashes of ROMs got Wi-Fi without issues.
Hope it helps.
