Wifi slowdowns, come and go. What to do? - One (M8) Q&A, Help & Troubleshooting

Just got a used replacement M8 and Wifi download speeds won't break about 2Mbps most of the time!!! Upload speeds seem unaffected (but they are slow anyways here @ 4Mbps) All my other phones/pcs would run about 32-33Mbps/4 on wireless via my 35Mbps connection, *including my old M8.* Seller told me its never been rooted and is stock.
I noticed if I turn airplane mode on and then off, the wifi download speeds return to normal for a short while, then revert to the <2Mbps downloads. I have tried factory reset of both wifi router and phone. Clearing cache on phone, power settings, NFC/BT on/off, etc, etc, to no avail... I am running Android 6.0 (6.13.631.7)
I'd love to figure this out. This phone is mint that I got and this is the only issue, so would hate to get rid of it due to this.
Thanks if anyone has any ideas...

Anyone?
I could use some ideas.
Not sure if I want to keep the phone if it's gonna slow down so bad on wifi all the time...

I bought the phone on Swappa, and between them not responding what so ever to my concerns and zero replies here, I don't think I'll keep this phone. Don't know what else to do...

3G stuck in upload...HELP

So last night I was listening to Slackers and all of a sudden it stopped working, I checked the 3G signal and it was stuck in upload, with no bandwidth on the download side. I tried rebooting but when I do that 3G is still stuck in upload arrow with no download activity, worse of all, it will go into reboot all by itself since gmail is trying to sync..I don't know what to do, could it be that Slackers killed my radio? I already forced stopped and clear all data, I also have Virtuous 3.1, did a Nandroid restore, pull the battery...etc and still stuck in 3G upload only...any suggestions? I am hoping I don't have to RMA the phone back since I have to restore back to stock, with S-ON..
Yep, same problem here. Started up about an hour ago, I was using remote desktop, it started getting slow and dropping the connection... Then it completely crapped out. No download activity, the upload arrow is stuck or flickering. Download arrow does nothing. Can't load webpages or use anything that requires data. Apps are trying to refresh constantly, but not receiving data. I use about 20-30 gigs of data a month sometimes... Maybe I wore out the antenna... I hope it starts working soon and turns out to be a network issue on Verizon's end... But I have a bad feeling about this one. I think it's dead.

Hmm...where are you located? I am in SoCal..I am starting to wonder if this could be a network issue...I really hope this isn't a hardware problem
FWIW, this might be causing the issue..let's wait and see, anyone else experienced something similar?

It is DNS test by going to 74.125.224.18 on your web browser on your phone
FAAACK, I just reinstalled my rom and everything trying to figure out what was going on, then I was shopping for replacement antennas and looking up warranty information... I'm in Gig Harbor, WA quite a ways north of everyone else, but maybe it's out all over the west coast. It went out exactly when those howardsforum people said it did...
I'm glad to hear it's a networks glitch.
Now, for a new rom... I think I'm going to try CyanogenMod.
...aaand we're back! The 3g is working fine for me now.

Heh, here's another one to add to the pile of "OH NOS SERVICE DOWN"

[Q] Wifi loses connectivity after period of inactivity

Hello,
I've searched around the Epic 4G Touch forums as best I could, but sadly I couldn't find anything that was exactly this problem (although I found some interesting articles about wifi sleep time but they don't seem to apply). I'm experiencing an annoying issue where I can connect Wifi just fine, but if the phone is left for a small period of time (~10 minutes), wifi appears as if it's still connected, however it cannot send/receive data. When this happens, the wifi status says it's "connected", but there is no data connection. The only way to to get the data back is to turn off wifi, wait for 3/4G connection to initialize, then turn Wifi back on to refresh it...then it's fine again until I set the phone down again.
I had this problem on stock EL29, so I rooted and flashed Phantom Blazer ROM (very cool ROM, but I'm still experiencing the same issue). After reading the threads on here about wifi sleep times (apparently they're backwards with ICS roms), I've experimented with every setting, yet I still have the same issue--Wifi is fine as long as I'm using the phone, I set it down, after about 10 minutes pick it back up, says it's still connected, but no data connection.
has anybody experienced this problem with this phone? I'm about to unroot my phone/go back to factory so I can take it in to a Sprint store, the problem is they (trying not to be offensive) don't seem to know very much about this device. I thought I'd ask the pros before I return it, get an iPhone, and have to eat my words about how cool Android is vs. iPhone in front of all my friends. I'm hoping there's a reliable ROM or app that can resolve this vs. having to just replace the device!
Thanks for your help!
I'm not the only one
I'm not the only one with this problem:
edit: I can't post links to androidforums.com or anywhere else, but this same problem is all over the interwebs and nobody has a solution.
I'm sure it's not my router as my ASUS tablet/laptops/girlfriend's iPhone experiences no connectivity problems. I'm thinking this is a hardware problem with some of these devices. I will unroot/reset to factory tonight and let you know what happens.
What channel is your router on? And what type is it A/B/G/N?
This is s known TW ICS bug, most likely kernel related. Almost everyone is having this issue and there is no fix until Samsung decides to repair it. There are quite a few posts similar to this one. If you're using XDA's search function, it's not very good. Try using Google next time and search XDA that way.

Hey guys, thanks for the response. Just before I unrooted/reset to factory I tried one last solution--download an app called "Wifi Fixer". It has resolved a lot of these problems. It's not 100%, but after testing it for a day so far, I've only had to manually refresh the connection once or twice. It's a lot better, even liveable, and I won't be resetting to factory afterall, at least not until Samsung provides an update. So if anyone is having the same problem, try Wifi Fixer, hopefully it gives you a similar level of success...I'm not super happy about having to run another background process all the time, but it doesn't seem to affect battery, and the fix it provides is worth it to me.
Cheers!
Huh - a couple of things. Noticed this problem crept back in FF18 and didn't know why until I went back and checked the wpa_supplicant.conf that I'm using. The line ap_scan=2 was missing; after adding it back in the signal strength is back to full and stable.
I'll bump the thread but it appears the config changes here still hold after all:
http://forum.xda-developers.com/showthread.php?t=1569348
This should also avoid having the WiFi fixer there as you can specify the country in wpa_supplicant.conf manually.
Thanks for looking in to this! A couple questions from a noob like me though:
When you say the problem crept back in FF18 ... what does that mean? Is that something that exists in the "stock" version of the Epic 4G touch from Sprint?
The manual config file tweaks you're describing ... is that something I can perform myself?
Basically I'm wondering if it's "safe" to revert to stock in order to get consistent wifi signal, or if it's something I'm experiencing because of the ROM I'm using.
Thanks!

[Q] ICS 4.04 (basebad I927UCLJ4) WIFI issue?

**Baseband I927UCLJ3** sorry if that threw anyone off.
Hey guys, I am wondering if anyone has experienced any wifi connectivity issues on the new update.
I dont have any issues connecting to wifi, but for some reason, it wont stay connected for very long. It seems like after I go out of range, it simply wont connect to anything, and I have to manually connect to my network.
The problem is I have been blowing through my data plan, thinking I'm on wifi, since everywhere I go I am normally on wifi. But in actuality, because my phone hasnt been auto connecting to the networks, I have gone through half of my data plan in about a week.
This has only happened since the 2nd release of ICS. The first one work fine for me (expect the black light issue, which I didnt really care that much about).
Any help would be greatly appreciated!

Hello,
I believe wifi has nothing to do with baseband. Probably there is something wrong with your phone and the new kernel wifi driver...
I'd try removing the access point and re-creating it, and playing with the advanced wifi settings.
Also, try rebooting the router/wifi access point.

Thanks for the info!!! I looked more closely into the settings and for some reason it was set to turn off wifi when sleeping.
I feel a little stupid, but I'm glad I got it sorted out.
I really appreciate the help.

WiFi crawling

Search function is down right now, so please excuse me if a similar question has already been asked!
For some unknown reason my WiFi started crawling. My other devices when connected to the same network are getting anywhere from 9 Mbps to 25 Mbps. My OGP is getting .01 Mbps to .04 Mbps (yes, the decimals are in the right place).
I've tried restarting the phone, the network, and all of the devices on the network, but the crawling speeds on the phone still stand.
The phone is running stock right now, and had been running OK up until yesterday...
I'm wondering though if maybe some program I installed yesterday (free app of the day, droid of the day, etc...
) might be the culprit. I installed a few apps from the Play Store yesterday morning, but the slow down didn't show up until later in the evening. If one of them is the cause, would uninstalling it/them typically undo the damage?....
Any thoughts as to what might be going on, or how to fix it? The only thing that comes to my mind is to reset the phone to factory stock. Is there some way to reset the WiFi portion of the phone or OS without having to reset to stock?

[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
