Hey guys. I'm having a very weird WiFi issue on my A520F.
Today the WiFi froze. It wouldn't turn off when I switched it off. After I while it turned off but took ages to turn it on again.
I factory reseted the device because I thought it was a software issue. It didn't work - after the first boot it was the same.
After a while after this, the WiFi started working again, but only for a period of time, then it would just freeze again for apparently no reason. Switching it off and on solves the issue for a while, then it freezes again saying that my WiFi is limited.
I can't take any logs since I'm not rooted (and don't have a PC to use ADB), and this is really scaring me since it happened out of nowhere. An hour before this started happening WiFi was working just fine.
I haven't installed anything unusual today, just connected for the first time on a new, but trusted, WiFi.
I've also reseted my WiFi router to its factory settings, thinking that it could be the issue, but the problem persisted. My Chromecast works just fine on the very same network.
Did this happened to anyone before? I've tried to root my phone a while back and, since it didn't worked out, I gave up and flashed the latest firmware from my country. This phone originally came with German firmware in it and I flashed it to a Brazilian one, which is the one I'm using and had no issues so far.
Can this be a hardware issue?
Thanks in advance!
So I guess I'll end up solving this on the weirdest way I can imagine.
After I posted I logged into my modem's settings and took a log at its logs. Seems that the moment this issue started to happen was near the time that the DNS server my modem was using started to fail.
I never thought that such a simple thing could mess this things like this. I mean, the DNS server is essential, but how that could freeze my phone's WiFi? Either way, I changed the DNS to Google's DNS and since then I haven't had any freeze or disconnetion. I'll test a bit more to see if the problem is gone.
Well, I do believe that I found the root of the problem.
As some of you may know, modems tend to stay on for a very long period of time (no one wants to lose internet connection, so we rarely reboot then), and for reasons I don't know (and as a tech support guy I've seen this happen A LOT) they freeze sometimes and only work again after being completely turned off and on.
Since the issue started again when I was messing with the modem settings (trying to change the DNS again to see if the problem would return), I decided to give my modem a few minutes of rest.
After that, I've powered it on again and went through the initial setup (my ISP provides an simple wizard when you first connect to the WiFi) and up until now I'm not having issues.
I'll wait a few more hours to report again, but so far so good.
So it seems that giving those things a few minutes rest every month or so isn't a bad thing at all.

Hey all. I need some advice. This morning my G3 (D850) dropped WiFi connection for no reason. It says the signal is good but the network info says saved, secured. It will attempt to connect over and over again and if it does connect the signal is weak as can be and it drops the connection within 2 seconds. My coworker has a G3 also and is connected to the same work network I am. His connection says excellent where as mine said good. His device connects just fine with full bars. I'm baffled. I've already tried manually selecting 2.4 Ghz and 5 Ghz instead of auto select and that didn't help at all. I've tried manually turning off WiFi and turning it back on. I've tried turning airplane mode on and then off to refresh the connection and that didn't help. I've done a battery pull as someone in one of the android authority forums suggested that (apparently I am not the only one having this issue.), didn't work. I've unchecked WiFi optimization - no dice. There was another post on a different forum here on XDA that said turning off WiFi and then deleting the WiFi config folder located in data/etc/wifi and then rebooting fixed the issue for them so I tried that. After reboot when I tried to turn on WiFi my G3 rebooted itself. Does it everytime. SO, I had to restore to a nandroid backup (btw I'm on rooted stock 10f) to get the phone to stop hating my WiFi toggle attempts. Last ditch effort I did a factory reset hoping for an easy fix... Nope. I don't know what else to try. It was fine yesterday all day. This morning it was perfectly fine and then randomly started having this issue. I haven't altered any system files whatsoever. I really don't want to send my device to LG for warranty replacement so I'm hoping someone can help me out that may have had this issue and resolved it. The only difference between my device and my coworkers device is he is still on 10d and I am on 10f. That could be the issue I guess but that doesn't really explain why my device has been perfectly fine until this morning and I've been on rooted 10f for weeks. I am planning on flashing back to straight bone factory stock 10d when I get home here in a few hours from work but Idk if that will help or not. Judging from the amount of google search results of "LG G3 WiFi connection problems" this seems to be an issue for several people. I won't know if it's on the software side or hardware side until I get home but in the meantime has anyone had these issues at all? People have had success in changing to Static IP but I would have to do that for every connection I attempt to connect to and that's a pain in the a$$. Also, that does nothing to identify the root cause of the issue. Any help would be greatly appreciated. =)

Thanks for the reply. So it turned out my phone just randomly decided it doesn't like my work network anymore. Idk why lol. I got home and it hooked right into WiFi. Gf's WiFi and open networks as well. I call shenanigans. I went ahead and flashed back to 10d anyway though.

I am having the same issue! But it is happening in other networks too...sometimes I get the phone to connect but it only works for a while and when I check the networks it only says Saved, even if I try to connect again
Having the same issue, whether at work or home, my wifi has become near useless. I've even gone as far as trying a different ROM. Didn't work.
Same thing here
I also have tried factory reset, installed a new ROM, changed settings in my router... but the problem remains I don't know what to do anymore, I use wifi a lot!! I searched through other topics but no one seem to know how to solve it. Unfortunately my warranty already expired, I took my phone to some technicians but honestly it didn't help at all...they all said it was a software bug and I should wait for an update but if it was just that a new ROM would fix it,right?
I am not very familiar with phone hardware but I assume that if it was a hardware problem I wouldn't be able to turn it on or connect to any network, right?? (any experts here???)
Any solution is welcomed.
anyone please?? :crying:
P.S : I tried a new baseband, new kernel and new ROMs. So far, nothing changed.
I can connect sometimes but get kicked out within minutes. At other times I only get the saved,secured message.
This is happening in every network
I just got an LG G3 last friday (Black Friday) on T-Mobile (got tired of Sprint). Anyway for the most part this phone has been great. A minor glitch with a game (possibly from porting it's data over from my S3). The main problem I have is with the WiFi.
First off WiFi calling sucks. If I don't have 3 or more bars on my WiFi connection the call gets fuzzy. During one call that was clear it just randomly dropped. So that isn't cool.
Secondly, if I connect to a WiFi network at home or work or where-ever and then go somewhere else and come back or go to another place with a network I want to connect to it won't connect at all. It will show all the networks and give me the option to connect. But instead of connecting it will try to connect for a long while and then just give up. I cannot get connected again until I reboot.
I have tried the suggestions found on this thread (and other places): http://forum.xda-developers.com/lg-g3/help/lg-g3-wifi-issues-t2829811
No luck with those suggestions. Which include the following:
Turn off and back on the wifi radio.
Disabling the "wifi signal is weak" option.
Disabling the battery saving for wifi.
Forgetting the network (my network list was automatically imported from my Google account).
Installing the "WiFi Manager" app and enabling the 5GHz channels (US) and changing 2.4GHz channels to "Complete".
Made sure that "Internet unavailable" option is disabled.
Made sure that "Keep Wi-Fi on when screen is off" is set to "Yes".
Disabling NFC.
Disabling BlueTooth.
Disabling Wi-Fi calling.
I don't have problems with a weak signal. So I am perplexed. My Samsung Galaxy S3 worked just fine on these networks. Restarting always seems to allow me to connect again. But I shouldn't have to restart every time I want to connect to WiFi.
All of my other wireless devices connect just fine in the household (a PS3, my fiance's Moto X, my old S3, MacBook Pro, Lenovo Windows 8 laptop, an HP running Ubuntu 14.10, and another Lenovo running Ubuntu 13.04).
Why is an older model phone doing so much better than the G3? Both phones are rooted (old and new). Does anyone have a fix? My phone is currently running LG's factory rom "D85110m". That is with Android 4.4.2 (my old S3 is on a cyanogen rom of the 4.4.x series as well).
Please help me fix this. Otherwise I might return it for an S5.
Thanks!
**** Update ****
Per my below post, it seems I have fixed my problem. I ended up doing two factory resets, unrooted, and did a final factory reset to fix the problem. Then I switched to the PurpleDrake method to root it the second time (and it worked really well without any issues).
Good luck everyone!
**** End of Update ****
Try to factory reset the phone. I don't know what version you are on but I assume its 10m

It is on 10m. Do I need to unroot before I do the factory reset? I have never had to do one before.
So it appears that doing a factory reset does not fix it. I guess I am taking it back and having them replace it. And I will demand it be a brand new one since I just got this phone a little over a week ago.
SOLVED!!!!
Ok, so I finally got it fixed. Albeit accidentally as I didn't expect it to be fixed at this point.
Here is what I ended up doing:
Two factory resets.
Unrooted the phone (via these instructions: http://www.androidrootz.com/2014/07/how-to-unroot-lg-g3-all-variants.html).
One last factory reset at T-Mobile store by me (because they forced me to).
The wifi did not start working correctly again until after that very last factory reset that I did. The unroot process also does a factory reset. But, and this may be key, it downgraded my phone to 10c from 10m in the process. I then did an OTA to 10m after the final reset.
I unrooted it because T-Mobile's diag software detected it was rooted and said that made the warranty invalid. And after I unrooted it I took the phone back to the store and demonstrated the problem to the employee that sold me the phone in the first place. He tested it for about 10 minutes and came to the same conclusion as myself. He then had to go to his manager to approve the replacement.
They got out the new phone to replace it with then the manage told me that he was required to have us to one more factory reset. So I went into the settings on the phone and did one last reset. And for some reason, since this point, the wifi problem has gone away.
I think it is possible that something I did to the phone caused the problem in the first place. But since I did so much to it in the first few days (rooted and installed a ton of apps) I am not entirely sure. My two current theories are it was either caused by this malware infected flashlight app I installed that kept popping up the Play Store to install a particular app. Or it was caused by the rooting method I used.
The original rooting method I used was "Stump Root". So the second time around I used the PurpleDrake method. This is a tiny bit more tedious, but very effective and it didn't seem to break anything. Further, when I installed TWRP I made sure that I grabbed the recommended image for it that is specifically for the US T-Mobile LG G3 device and installed that using Flashify.
After I got it safely rooted I tested the crud out of it and it seems to be working fine.
One last thought. It is possible that somehow Titanium backup caused the problem when I restored text and call logs. But I seriously doubt it.
Anyway, if anyone has any questions for me about this please shoot me a message. I am more than happy to help.
Thanks,
Patrick
Hopefully I word this right so i can clearly describe my issue. About a week ago I had a glitch with a custom ROM (I am rooted and S-OFF). Before the glitch I had zero issues, data worked created, WIFI worked great, handoff between the two seemed flawless. This is where i am at now.
After taking an absurdly long time to actually be able to wipe and reload a ROM, the issue started. Run just WIFI, no problem, run just Mobile Data no problem, but once I connect to a WIFI ( have tried several WIFI connections and hotspots) this occurs. Approximately everry 5-10 minutes you can see the data connection momentarily drop then reconnect, giving me 3 notification sounds. Annoying to say the least. Doesn't affect the performance of the device but you can see how annoying that would be. I'm gone through all of the settings I can think of in Dev and in settings and can't figure out why it keeps doing this. I was originally told to try a radio but data is perfect if no WIFI present on the device so I would rather not flash and wipe if I can help it.. I know the simple fix would be to disable mobile data at home but that doesn't cut it I would like it to be on as it normally would be. AS a note I have tried full wipes and several ROMS they all present the same issue.
If anyone understands and can help, and you need a logcat I will gladly provide one.

Hi everyone, I'd really appreciate any help anyone could give me in solving this problem...
I upgraded to MM a few weeks ago and at first had some odd WiFi issues where the phone would not connect, or stay connected very long. After about half a day of tearing my hair out, clearing my cache, and reinstalling apps it all seemed to "come good", and had been ok for a few weeks.
A few days ago, however, everything went bad again. Here is what is happening:
On my 2.4Ghz wifi network, when the phone is woken up using the power button or double tap, WiFi does not work. The phone reports that it is connected to WiFi, and (according to the Ping Tools app) has an IP address, but there is no connectivity to the outside world (or even to my router or NAS box). After about a minute or so, the connection magically "comes good" again, and the WiFi works normally. This is very frustrating as while the phone is asleep it has no IP connectivity so I don't get any notifications for email/messages etc. I have the default "yes" setting for the "Keep Wi-Fi on when screen is off" option BTW.
I have discovered that if I switch to the 5Ghz WiFi network on my router then I do not get this behaviour - the WiFi stays connected while the phone is asleep and there's not the same period of no connectivity when it wakes up. Unfortunately the 5Ghz network doesn't reach to the front of my house so this isn't a viable solution.
I have also found that the odd behaviour does not occur if I disable Bluetooth on the phone. Since I use Bluetooth audio in my car, it's a bit of a pain to disable/re-enable it but it's the workaround that I'm currently using.
The strange behaviour does not occur if I reboot the phone into Safe Mode... the WiFi stays connected while the phone is asleep, and 2.4Ghz WiFi works straight away when the phone is woken up. This seems to indicate that an app might be the culprit.
To try and diagnose this I have
- cleared the cache and rebooted a number of times, to no avail
- done a factory reset and reinstalled my apps from Google Play, but end up in the same (broken) state
- changed the default channel for 2.4Ghz WiFi on my router several times
So I'm at my wits end now. I guess I could do another factory reset and reinstall my apps manually, one by one, and see which one (if any) breaks things. But I'd like to to try and avoid this. Does anyone have any suggestions as to how to determine what could be causing the problem?
Phone is an H815 running Android 6.0, V20a-EUR-XX. Totally stock, locked bootloader.
Sorry for the lengthy post.
I have approximately the same thing. Switching Bluetooth doesn't help in my case. I had to wipe cache from within the phone to make it get better again.
One other thing was to throw away my aluminium bumper. Do you maybe have one ?

Oh, I got excited at your case suggestion as I got a new case a couple of weeks ago which does have an aluminium bumper. But I just took the case off and alas the problem remains.
Unfortunately clearing the cache doesn't work for me. I also found a setting under Backup and Reset to reset network options but this didn't help either.
Next step might be to reinstall the OS or try the repair option in LG Bridge. Unless anyone else has a better idea?

Tihs issu not MM specific exist on LP
Try another chanel (In router)and use only N 2.4 Ghz
But is see you try..
Go and use warranty.!!!
I think I've fixed it. I just started uninstalling apps and checking to see if the behaviour persisted after uninstalling each one. After uninstalling TuneIn Radio the WiFi started working with Bluetooth enabled again. I reinstalled all the apps that I uninstalled (including TuneIn) and everything seems to be working again. I doubt it had anything to do with TuneIn - just a weird interaction of who knows what. It's not terribly satisfying and I suspect it will happen again, but hopefully this thread will help someone who might have the same problem.
I've had my G3 for 18 months now and over the past 4 weeks I've had problems with the wifi dropping and reconnecting again. I tried the tips from people I found on other websites but nothing cured the problem. Usually I would forget the wifi and then reconnect to it. That would usually work for a few hours, but then it would drop again.
Around the same time my SD card would unmount too. I originally put that down to it being old, so I bought a new one, but again, same problem. I've not been using one since.
3 days ago the battery drained itself within a couple of hours and the phone failed to connect to any wifi at all.
In fact it kept resetting itself and I had to take the battery out so it could turn on again.
I purchased a new battery and the life has improved a bit but the wifi problems persist.
I did a factory reset hoping that would cure the problem, but nope, still not connecting to any wifi.
I was a sent here to seek advice from a Techie Forum, so hopefully you can help me out!
I've had a quick look and I feel a bit overwhelmed with all the root and flash talk....
Does this problem all come down to Lollipop being a pain in the ass?
Is rooting the only way to get around it?
Thanks in advance!!
Well, you've either loaded some software that has caused the issue or you have a hardware problem somewhere. If it's been working for 18 months, it doesn't just "go wrong" - something has to change.
So, have you loaded anything recently which you also reloaded after the full factory reset?
Alan
When you have no internet, would you mind going to about phone > hardware info and check what ip adress you have? Most likely 02:00.. That's my exact problem.
Never loaded any software on to the phone except official updates or apps from the store. As i said, first it was intermittent and now it wont connect at all. Bluetooth connection has the same problem.
On the "about phone settings" it just says Wi-Fi mac address unavailable, ?
Android 5.0?
Did you install any custom roms? I'm trying to find a way to solve this but I'm failing to do so.. You can send your phone to warranty, if you still have it and they'll give you a new one :/
yes android 5.0, I've had my phone since July 14 so out of warranty now I would think. No, I've never used any custom roms. There seems to be a lot of other people with similar issues, and they have gone down the root route and delete a file from data misc wifi wpa_supplicant.conf. ?
Might have to try that, but I've never done it before.
Don't think that would solve your problem since I've already tried that and failed :/ It sucks really bad, rooting definetely helps since this is a root issue..
Think I'll just take it to a repair shop. I's a shame because I really love the the phone. It's got to be resolved though because I can't keep going without WiFi. Still got 5 months before I can upgrade too.
I don't think sending it to repair shop is a good idea.. At least 100,150€ to fix it.. If you sell the phone for 150-200€, you can get close to the money for the G5 which will come out in about a month.. Try to use data, dunno...
After updating to stock MM on my LG G3 D855, I had problem with wifi but only at home. It turned out to be a problem with IPv6 DNS servers on my home router (VDSL). I tried 2 solutions and both worked - first I tried app that makes VPN connection with correct DNS servers: DNSet (https://play.google.com/store/apps/details?id=com.dnset) and it worked. Then I tried to find (and succeeded) IPv6 DNS setting on my router and there I entered Google IPv6 DNS servers. After that, I uninstalled DNSet and everything worked.
