Marshamllow Wifi problem! - G3 Q&A, Help & Troubleshooting

I am on V30n rooted and I was before that on V30j I have D855 that was working all great, in recent month it just won't connect to wifi, it connects sometimes and most of the time I just see "saved" and it does not want to connect,
sometimes it connects for few seconds and dissconnects, I searched all over the internet with no clue of solving this!
btw I changed battery a few months ago but all went well since then.....
is it a hardware failure?

Hi there, same problem for me...since last week, it won't connect to wifi. When i toggle wifi on, it stucks on "activating wifi" and I can't deactivate it. I'm on marshmallow too, same version V30n , but not rooted...Please help...?

LG Optimus G With Rogers Weird Wifi Problem

So I am having some wifi problems. Like most I have 5 or 6 wifis that I connect to on my phone. My issue is that I will need to use my data and my phone's wifi is stuck on trying to connect to a wifi network that is no longer available. I can't turn wifi off or anything. My only fix is to restart the phone. Any clues?

Yes. I believe I'm experiencing the same thing.
Here's my situation, I have the Rogers LGOG (Not rooted) and the reception @ work is extremely poor. So I turn on wifi to connect. I'm able to connect to my corporate wifi, but when I leave to go between floors and I'm out of my wifi range and return, I'm not able to connect. WI-FI is ON and it keeps searching for hotspots, but I'm not able to connect and the only way for it to work again is to reboot. Now, this does not happen consistently, but it has happened a few times to where I'm wondering is this a problem with the OS or is it the phone.
Any thoughts on this to point me to the right direction would be greatly appreciated. thank you.
Same problem with F180K, but there an OTA update arrived yesterday saying "Wifi bug fix".
Cant tell if they really fixed it, cause im waiting for my flight, so cant test it right now.

wifi hotspot problem

First i am sorry about my english
I have a problem with a wifi hotspot. I lost connection all the time or not all the time but every day this happens. When im online with my computer and my phone is hotspot everything works well but suddenly i got message "no internet access" My phone notifications show wifi hotspot is on but its not! My computer and other phone not notice that at all but if i turn off that wifi hotspot and turn on its working again. How can i fix this problem? This is so annoying. I have android 4.4.4
This might be of some consolation, it also happens to me quite regularly. I often have to put my phone into airplane mode and back again to reset the network. I think it's a carrier network issue rather than any software. Could be wrong though

Wifi problems

Hey guys,
i have a weird problem with Wifi on my phone (LG Optimus G). Since Android 4.4.2 and now also Cyanogenmod 12 i got problems with my wifi. It shows me that my wifi is connected, but i dont have any connection to Internet or Network. I have first to switch wifi off and then again on to make it work again. This is happening 5-6 times each day.
With Android 4.1.2 i dont have this problems, wifi is working perfectly. Would it be possible to import the wifi driver from 4.1.2 ?
I used for sometime the app wifi reconnect to not switch the wifi alle the time manually on and off, but this is also not a solution.
I hope someone can help me.
regards
Noone a Idea ? What could i do alone ? Where can i check the wifi logs ? Could i take the driver from 4.1.2 ?

Wifi disconnects when screen off

Wifi in H818N disconnects when screen is off, which is very irritating.
The option to keep wifi on when screen is off is set to Yes in the advanced wifi settings.
Anybody else facing this issue?
I have the same problem with my H-815, but it doesn't disconnecs right away, it disconnects after 10 min or so, and that doesn't happen always.
Yeah, it intermittently disconnects, though connects back automatically when screen is turned on. Its weird and irritating.
Same problem here
As well as my G4 will get up to 100% CPU usage for a while, every time the Wifi/ Data is connected.
Try settings, wifi, 3 dots menu, advanced wifi, keep wifi on during sleep, on
That is already on as written in the first post.

Some people just never read but the title, same problem here.
I soft bricked my H815P about a week ago and when I reinstalled the appropriate KDZ, I found that Wifi keeps turning off, ¿maybe a solution in the build.prop file?
Sent from my LG-H815 using XDA Free mobile app
I have the same problem using 5G router. I'll try using 2.4 network.
Update: No more problem using 2.4ghz, i think it's a bug only when connected at 5ghz wlan.
Same...on 6.0 any solution?
Same here. I´m on Android 6.0 MM with my LG G4 H815.
edit: i have no 5ghz network...
Doze may be causing the issue
I have the same problem, but only on my home network. Not at work/school though.
Try going to battery settings > usage > battery optimizations and disabling/ignoring Wi-Fi. I will be testing this out when I get home.
Update: seems to have fixed the issue. Wifi is on already when I wake the screen, even after a while of sleep.
This sttings solved my problem, thank you.
here is my fix for the wifi disconect issue :

Strange WIFI Issue with my router

Hey folks,
I hope somebody can help me. I have a very strange issue with my Sony Xperia XZ2 compact and my Wifi. It won't connect under any circumstances. It says "Establishing connection" but nothing happens. It worked in the first place but since two weeks, it stopped working.
What I tried yet: -
resetted the phone to default and updated to newest android
- resetted the router to default
- changed the wifi channel and Name/Password
The strange thing is: The phone connects to every other wifi, except my home wifi. And every other phone does connect to my home wifi. It seems to be a issue between my home router and my phone. But I have no clue what else I should do.
This really sucks. I really need Wifi at home.
Thank you for your help!
well,i cant turn on the wifi option now
and it will reboot randomly as i try to turn on wifi
even i could turn on wifi still there is no signal and unable to connect to everything
BUT MY LTE WORKS VERY WELL
4G SIGNAL IS STRONG AS FXXK
Bump, seeing a similar issue with my mother's phone. Wifi works at phone for her, but not at work.
