I am experiencing the same issue, same phone and rom i9195 JDQ39.I9195XXUBMJ7. Wifi works after reboot for about 10 minutes and then stops responding. It may stay connected for a few hours after it stops working, but the phone can't send data over it.
I have wiped data/factory reset the phone to no avail.
I read somewhere about a few people with other devices on 4.2 having troubles with AES encryption on their routers. Might be somewhere for us to start troubleshooting. The other option is to just try downgrading to the previous version.
Hello. After upgrade my E975 I have a WiFi problem - it is slow. Speedtest shows up to 4 mbps when my PC connected to the same router shows 60 mpbs on the same server. I had France V20a and I have done factory reset because led notifications didnt work, now Im on V20 GER and WiFi is still slow.
I don't now exactly when the problem was show up, because i didnt testing wifi after update from JB. What should I do? Factory reset again?
Please, help me guys
i have the same problem...or an even worse one. after updating, the wifi signal is really weak. i cannot find networks that other phones (or our phone before the update) are connected to. i tried everything. factory reset. re flashing the rom , nothing seems to be working...can someone please help us?
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.

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 am using LG G4 US991 in Canada. It is unlocked and i am using it over Fido. With Android 5.1 I had no issue, everything was working smooth. Then i got the marshmallow updated and I had following three issues
1. Mobile data plan isn't working .... I used this link to configure the APN http://www.fido.ca/consumer/content/configure-unlocked-device-guide but no success. I factory reset the phone, restarted and tried whatever i could but still same problem ... Is it a known issue ? Is there a fix ?
the other 2 issues aren't that important as of now. Heating up and battery drain. I can live with those as long as my data starts to work.
P.S: The wifi is working with no issue.
Having this same issue but no luck in finding the procedure how to downgrade back to lollipop. My software version US991120c and it is a US cellular phone.

Thanks for letting me know. Seems like i am not the only one. Please let me know if you find something and I will let you know if i find something.
I am also having the same issue. Only wifi works, but no data connection.
Any news with this issue?
still no data connection for me.
Same issue for me, any known solution?
i am in italy & using us991 ... i also update to Marshmallow & facing same problem.. i try many things but no luck.. i think we have to wait for root this version first then problem may be solved ..... & try to downgrade can hard brick this phone .........
Did you fix this problem?
I just go the Marshmallow update and now my data is no longer working.
APN seems fine...
Hey
I'm in that same situation but I'm with Rogers. I did a factory reset, ttriple checked my APN, tried non LTE APNs, no luck.
Everything worked before the MM update.
Did you find a fix??
same issue. is there any way to downgrade?
I had the same problem on Sprint after taking the OTA. Here's what worked for me:
Connect to wifi
Go to system settings> system update
Tap each of the categories and wait to receive a pop-up saying it's completed before tapping the next one.( update PrL, update profile, etc) after each one is updated. Reboot and toggle wifi off. Mobile data should return. Again this worked for me on Sprint, I tried apns and reset to factory and nothing worked till I tried this simple approach. I am all stock, never rooted or forced an OTA. Let me know if it works or not for you
i'v found the solution.
here is a link for fix

With the auto update to 8.1.0 google killed my wifi.
with all possible tricks (safe mode, on/off, reset options...) I managed to get a connection but data is zero and from time to time poor.
what to?
can I roll back to previous version 8..0?
UPDATE:
I did factory restore from google servers. Still no working wifi!
SO: the wifi modul not working... Good buy nexus 5x I had a great time....
I have the same problem , do you find any solution ?
I have the same problem. It didn't recognize my wifi at home at all. Tried everything and had to factory reset eventually....
Now it still doesn’t recognize my wifi and I can't even start up the phone. How stupide is this
