Hello,
Tonight I tried two different ROMs on my T-Mobile G2 (USA) and experienced a very weird Wi-Fi unavailability issue in both out of the box. Wi-Fi is not active. I cannot turn it on. It's not that it can't find networks or died after an hour, it's as if the Wi-Fi module is missing to the OS from the moment the device booted. When I go to the settings menu, find Wi-Fi, and flip the toggle switch to ON, it immediately goes back to OFF. Rebooting does not help. Going to Airplane Mode and back does not help.
Some quick background:
My previous working build is Ice Cream Jibwich 2.0. (Link)
While rooting this phone, I followed directions for gfree, and did not get SuperCID, simlock-off, or S-OFF.
I use ClockworkMod Recovery. As of now I can recover to my Ice Cream Jibwich install with no problems.
Here's what happened on the ROMs I've tried:
CM9.1.0 (Link), Kernel 3.x., gapps-20120429-signed
Factory reset, clean install. There is no Wi-Fi as detailed above, and it doesn't even recognize my T-Mobile SIM.
So I try another ROM:
Andromadus Mimicry 1.5 (Link), gapps-20120429-signed
Factory reset, clean install. I did not install either EdKeys' WiFi Calling or the .19 Radio lib-RIL/GPS .so updater.
I do get mobile service this time. However, the Wi-Fi problem remains.
Since I can download something this time, I installed some diagnostics tools. Elixir2 reports that the Wi-Fi module is "unknown", its connection state is "uninitialized", and it thinks it's "ready to start data connection setup" in the Detailed State. logcat shows no errors that are relevant to Wi-Fi.
Dom's Diagnostic Tools has "Unknown" or "Not Available" for every category under Wi-Fi.
I have tried Wifix for Mimicry (Link), and I don't notice any improvement.
What am I missing, what can I look for, and what are my options? Your help is very appreciated, as I'm losing patience for Jibwich's lag and instability. I can live with it, but the people that I want to gift this phone to won't.
Thanks!
Just last week my DZ started to have a very similar (probably the same) issue. When I try to start wifi, the phone gets stuck at "Turning on Wi-Fi..." and never actually turns the wifi on. It started happening occasionally on EliteMod ICS but a reboot would often fix the issue. Eventually rebooting stopped fixing it however. I have since wiped the phone and flashed a new ROM (Andromadus Jelly Belly Beta 1), and the issue remains. The MAC address is shown as unavailable in phone status and when checking in Elixir, I see the same things that infinip sees.
I have read elsewhere on other forums for other phones that it may have something to do with a faulty modem file or something, but frankly I have no idea.

Sounds promising. Do you remember where?
Hi all since upgrading to android 4.3 the wi-fi no longer works, it just gets stuck at turning wi-fi on and nothing else happens, ive tried a different rom and different kernel to no avail and its not my router as ive tried it at home and work where it previously worked fine, any suggestions?
Thank you for your time reading the post and if you reply with suggestions you are awesome.
Give us kmsg.
Go back to stock through fastboot/factory images.
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".

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.

HELLO
I have exactly the same problem and I think we're not the only...
D855 :
-Wifi and Bluetooth doesn't work.
-Wifi keep turning on itself and the battery drain..
-3g/4g works perfectly.
-Downgraded on kk and Wi-Fi works so it is not a hardware issue
-Even on fulmics Rom Wi-Fi and Bluetooth doesn't work
HEELP ME PLEASE
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.

Have you maybe tried to change the kernel of your device? I have never done that so I am scared if I would damage something.
http://forums.androidcentral.com/google-nexus-7-tablet-2013/306730-wifi-stuck-turning.html
Here someone says it's the kernel that is having problems and installing a new one and going maybe back to the old one will fix it.

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.

i also faced wifi keep ON issue in stock ROM, but i restarted few times and It worked fine then... or you can try the MTK/Android settings by typing like some *#*#1234#*#* to access wifi and try on/off if any
--Please hit thanks if Helped:good:
I am having pretty major issues with the wifi on my G3 D855 - When I try to connect to a network (secured or not, doesn't change anything), it instantly sets itself to 'saved (secured)'. It takes multiple tries for it to turn to 'Connecting' and then it goes back to 'Saved'. If I keep trying, it eventually shows 'Authenticating' and then 'Obtaining IP address', after which it will connect to the internet for a maximum of around 20 seconds. This renders the phone virtually useless unless on mobile data. I am currently on the stock Android 4.4.2 KitKat, but before I was on CM 12.1 Snapshot, and before that was a CM13 Nightly. The issue started around 2 weeks ago whilst still on CM13, but it had been installed for a few days beforehand, so it surely can't have been caused by it (please correct me if I'm wrong). I tried to install .zips for different modems to see if this would change anything but to no avail. Any help would be greatly appreciated.
