Wifi has been spotty at best with new OTA - EVO 4G Q&A, Help & Troubleshooting

Ever since upgrading to the rooted, stock OTA ROM, my wifi has basically been unable to connect. I got it to connect a couple of times, but only for a very short while (possibly until I turned the phone off). Prior to this rom, it would automatically connect within a minute of arriving at one of the sites where I had wifi configured. All of the networks are properly configured--it just won't stay connected. It starts to, and then goes back to disconnected.
I have never had any problems with the wifi on this phone, with any ROM.
Is there a trick to getting it back up and running again? Is there a different kernel fo rthe new OTA that will fix it? I've searched and found others with the same problem, but haven't found a solution.
Thanks,
Dave

[Q] Data Connetion

Hello all!
I am having constant data issues all day where I go to use an app that needs it, it says that no data connection can be found or something. I turn the radio off, turn it back on and then it works. It's a good work-around but it does get very annoying. I've tried multiple 4.4.2 roms but no avail. I tried a different kernel but I couldn't even use the phone. Any ideas?
Same for me; I'm rooted now but it happened before root and after the JB ota updates. Annoying but otherwise I love this phone
I think this has been a known issue since ICS (I could be wrong though).
If anyone knows a fix that would be cool (I have GSM google play gnex)
My issues started late last night, lost data connection and it didn't come back. On my way home, it connected then lost again at home. Went to Verizon today and they couldn't figure it out, said possibly the radio is taking a crap.
On my way to work, it connects then gone. I tried flashing the radio, pulled battery, booted without sim, formatted cache and delvic. I have tried everything and think it's the end of the line for it
I've been rooted since the day I got it and had the issue once a while back but it straightened out and has been great since.
Certain CyanogenMod ROMs have trouble with the Network Modes sticking. Which carrier are you using? For my carrier, I had to have the correct APNs set to get 4G and MMS working. It might be that this is the problem in most cases, especially when the phone switches between 4G and 3G in spotty areas.

WiFi failed to connect. Speed to slow.

So I'm running stock 4.4.2 Rooted, and as of 2 weeks ago, I'm unable to connect to wifi at my gym. The signal strength is strong, yet I try to connect and after awhile of attempting to connect over and over again nothing happens, but sometimes I get an error saying "failed to connect, network to slow" or something along those lines. My wifi works perfect fine at home though. All info I could find just leads to factory reset which won't happen for me. I've deleted that wifi over and over and put the password in again several times, no change. It's only me with this issue though and as I said, friends with the exact same setup can connect perfectly fine. This just happened out of no where one week after working fine.
Well now that I think of it, over a period of two more weeks before the no connection at all issue, it was starting to turn into a crawl for speed but only for me.. Stock everything Rooted, and stock kernel.

.....have the gym reset their router..... cause if you can still connect to other WiFi out there then i think it less of your phone and more of the router at fault here
Well, then why is only my phone effected? People with the same version and Rooted and such don't have this issue

my only other suggestion would be to flash Ktoonez(might have misspelled his username) TW Kernel and Tweaker and to Flash the NDC modem; from personal experience NDC modem gives me better 4g signal....yet it also gives me better WIFI signal as well as connectivity, some will say it doesn't affect WIFI but it did for me so you can try that since you don't want to Factory Data reset it.
Well my phones disconnected anyhow. I can only use wifi really so I keep it in airplane mode with wifi enabled

[Q] Wi-Fi issues with the new update?

So i recently got an update for my phone, and it auto downloaded it. I installed it, thinking it would bring improvements. Turns out, it messed up my wifi big time. Phone keeps forgetting networks it was connected to, and its a hassle keeping a stable wifi connection. It keeps disconnecting for no reason. No, its not a problem with the router. I tried resetting it and still the issue persists. Moreover, my family members phones and my laptop connect just fine.
Troubleshooting steps ive tried are restarting, and even resetting my phone. Did not work. Does anyone know how to fix it? It would help out a lot! Attatched screenshot with my firmware version. Thank you!

[Q] Major WiFi issue out of nowhere?

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

Very weird WiFi issue

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.
