[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

[Q] Unable to connect with wifi on zenfone 2

I'm unable to connect through wifi on asus zenfone 2. I have tried the suggestions given in net but it didn't help me that much. It keeps on connecting and dropping then reconnecting. It's really frustrating me a lot. :crying: . But it worked fine for me before. Not sure it's because of latest firmware update or not. If anyone had this problem and rectified it means pls let me know the solutions. Thanks in advance.

Please see our FAQ support site for WiFi troubleshooting assistance: http://www.asus.com/us/support/FAQ/1006657/

Thank you for quick response
Hi Asus,
Yesterday night i just tried my luck to connect with wifi and it got connected . But after current went and came, i tried to connect again but this time it did not connect to me. I could not understood the reason for it. I restarted my phone & modem but still same. Pls tell me what could be the reasons for this wifi connecting issues.

See of your router/ modem has a firmware update. If it does take it. That usually sorts these type of problems.

Are you able to connect to other WiFi networks? If not there are several helpful tips regarding basic troubleshooting techniques in an app called ASUS Support: Please see Apps/ASUS Support/Assistance/3G-LTE-WIFI-GPS/Cant connect to WiFi.
If you have any other questions or concerns please feel free to contact me direct at the email below.

Having the same problem
Hello, I'm from Paraguay.
Got the phone a week ago, and at first Wi-Fi connected okay, no problems at all.
Since yesterday, it hasn't been able to connect to Wi-Fi, it just keeps on disconnecting, saving, connecting again, disconnecting, and it never actually manages to just stay connected.
I have tried re-initiating the phone, putting it in airplane mode then turning it off again, forgetting all wi-fi connections and then connecting again, turning Wi-Fi on and off, turning the router off and then on again, and until now I haven't been able to solve the problem.
Right now I'm trying to check for updates to see if anything important's missing, but my phone provider is also being problematic by not letting me download updates using my network connection (though that's another problem I think I'll have to solve with my provider).
I was trying to avoid running a factory reset if possible, so I don't know what else to try.

Authentication Problem
I'm having a similar issue. Just like Blasterkat101, it was working fine for the first couple of weeks, but recently (possibly since the most recent OTA update), I'm getting "Authentication Problems" on any wifi I connect to. After I try to connect a couple of times, it finally works. If I walk out of range and come back, I get the "Authentication Problems" error again.
I already followed all of the troubleshooting on the support page, but those suggestions seem like temporary fixes rather than correcting the problem permanently.
In case it matters, I'm using the ZE551ML variant.

I hate to bump, but this is still a daily occurrence for me on multiple saved access points. I admit, I haven't done a factory reset yet since it can be such a pain, but is anyone else having this issue?
Any suggestions before I wipe my phone? I would really appreciate it!

Please try turning off 'WiFi Scanning always available.' To do this go to Apps/Settings/WiFi Settings/Advance Settings(menu in upper right corner)/Scanning always available/turn Off. If problem still exists, please see the following link for troubleshooting methods: http://www.asus.com/us/support/FAQ/1006657/

Not sure is this is helpful, but you could also try changing the Band to only 2.4 GHz or 5 GHz, depending on your router. It might help with stability.

Thanks for the responses, but I'm still stuck.
I did turn off "WiFi Scanningalways available," and that did not help.
I tried changing the 2.4GHz channels (with 5GHz disabled) on my router, and that didn't help. I also tried leaving only 5GHz enabled. That also did not help. But I did not expect it to anyway because this is happening on any access point I use (work, home, friends).
I'll do some more troubleshooting, but I think a factory reset is in my future.

I hope you could fix the issue?
Mine stopped having problems on its own, but it still got authentication problems from time to time anyway. No idea what's wrong.
And yesterday the phone just stopped being able to charge and battery got to zero. Right now it's dead, but I guess that's a completely unrelated problem I'm trying to solve on my own.
I foresee that returning the phone is in my future -.-

Even I was having the same problem. Tried the Airplane on, Wifi on, Airplane off thing; didn't work. But what worked for me was changing the SSID and security key of the router. Now of course you can only do this if you are on you home router, but do give it a try.

I've just updated the firmware on my zf2 64g2g and now my Wi-Fi is causing major problems. I connect but within seconds it disconnects and then I have to forget network to regain access. I know its not my network as my old n5 is fine and all my other devices. This has only started since the last asus update. My phone is unusable. Wish I didn't buy it tbh. Too buggy.

[SOLVED} This fixed it for me

TRY THIS. IT FIXED THE PROBLEM FOR ME.
There is a reboot option in your router settings page. Do that and it should be connecting fine.

Have anyone fix this issue? I just bought a Zenfone2 ZE551ML and wifi is always connecting and disconneting over and over.

try with static IP Address (not DHCP)

I also have 32gb 4gb Asus ZE551ml and can not connect to wifi network.
Also sim 1 card signal is too low and other phones signal has the highest . Any solution please?

wifi deep sleep issue (have to wake device to reconnect to wifi)

hey guys, I need some advice or assistance with a wifi issue on my D855 32GB, running Fullmics 6.1.
The issue is, every time my device goes into deep sleep, is inactive for a lengthy period, the wifi connection becomes dormant until i wake the device. Also, if i enter another area of saved wifi connection, I have to wake the device in order to get connected. For example; if I leave home wifi and enter work wifi I will not connect until i wake the device and vice versa (work wifi to home wifi no connection until device i awoken)
Please, can someone assist?
I did posted this before, got some answers saying it maybe marshmallow/doze related. If so, how do i make adjustments?
P.s. I tried several ROMs and same issue, however, when i first got my device, stock everything (Lollipop), the issue was non existent.
many thanks in advance fellow xda members.

I had/have same issue since first MM version of Fulmics, it was never fixed. You said you have it on other MM ROMs so I wont point fingers at Fulmics dev since not all users are experiencing it.
Things I tried to do to fix it:
NatusVincere said:
Yap, had the issue while I was on Fulmics.
Made my device useless since it repeated almost every time I turn off the screen so I had to drop this ROM and go to AOSP/CM based.
I tried changing modem to multiple versions, tried delaying doze, tried multiple kernels, tried same as you disabling app optimizations as well.

Only possible alternative solution instead of switching ROMs is to make device use internet connection full time, to make it never go to deep sleep.
Perfect app for that would be:

Issues with apps over WiFi after upgrading to Android 9

Hi. At the start of December, I upgraded my Mi A2 Lite to Android 9 and ever since then I have been facing issues with a few apps over WiFi. The following apps are being affected:
- YouTube
- Twitter
- Facebook
- WhatsApp
- Chrome
*These issues are only on my WiFi. On 4G or any other WiFi these issues don't happen*
The issue with Facebook and Twitter is the same. Both won't load any new feed and behave as if my WiFi is not turned on. YouTube only works at times, other times it would just keep loading and nothing would happen. Sending images or videos on WhatsApp is impossible now. It even has troubles making the backup to Google Drive on my WiFi. As for Chrome the issue is that sometimes even though WiFi is turned on, it would not load any page and just say that I'm not connected to internet. I've been reading other people's threads online and even emailed Xiaomi and Google. I tried the steps (hardware test etc) as told in the email by Xiaomi but that has not helped. Some said that using WiFi and Bluetooth at the same time caused this issue but I have used WiFi with bluetooth turned off yet the issue is still there. Now if this was a WiFi issue then I would have contacted my provider but with the same WiFi connection I have not faced a single issue on any other mobile devices and laptops. As for my WiFi I can't seem to change it from ipv6 to ipv4 (or I just don't know how to). If anybody has faced this issue and knows how to solve it then please help, It would be greatly appreciated. Thank you for your time.

Have you tried disabling Bluetooth and then reconnecting to the WiFi in question? Having both enabled at the same time causes WiFi speed transfers to be really bad, it's an already reported Pie bug.

Btw, can u see 5ghz wifi networks?
Cause i can and have same problem with slow wifi+bluetooth

Yes I have turned Bluetooth off and used WiFi like that but the issue is still there with all the apps mentioned

Any update on this? I'm having the same issue. Using a VPN seems to solve the problem but the connection is slower.

I am facing the same problem on my A2 lite Android One Pie. Even the further upgrades including March upgrade did not resolve the issue. It really sucks.
Has anyone found any solution?
Is MI even concerned or acknowledges the issue?
Is there a way to go back to Android 8?

Hello Dear Sajid Abid,
Good Day !
1st Remember One Thing. Downgrade Is Not A Easy Task, Downgrading Has Also A SIM Issue Problem,.But If You Still Want To Go Back Your Mobile Device From Pie To Oreo You Need To Unlock The Boot-Loader (Off-Course Unlocking Boot-Loader Will Void Warranty) Then Download Stock Oreo (From MIUI Forum) And Flash It With The Help Of IMFlash Tool. After Successfully Ported The Stock Oreo Rom You Can Close The Boot-Loader.
All Instructions/Steps Can Be Easily Found On A2 Lite Forum.
Here Is The Link Which Can Help For Resolving SIM Issue Problem.
https://forum.xda-developers.com/mi-a2-lite/help/sim-card-issue-downgrading-pie-9-0-t3874350
Have A Nice Day.
Thanks,

[SOLVED] Please Help - WiFi Frequently Disconnecting in Android Pie ROMs

The WiFi on my phone disconnects for about 2 seconds (every 15 minutes or so) for no reason at all. I have the same problem on EVERY single Android Pie ROM such as Lineage, Pixel Experience, AOSiP, AEX, etc. When the phone is in sleep mode the Wi-Fi will NOT reconnect, which means I constantly miss important notifications such as messages from friends. Also, when watching YouTube I keep seeing a message pop up saying 'Back Online' due to the WiFi disconnecting.
I have seen a couple of people on the forums with the same issue, but a solution has not yet been found. I know this is NOT a problem with my home broadband because I don't experience the same WiFi dropouts on other devices.
If anyone knows a solution to this problem, or just has a suggestion, PLEASE let me know as I would REALLY appreciate it.

Hi. Thanks for the response. I will keep that in mind, I can't remember whether I tried Carbon ROM before.
However I have to think this problem is related to something more specific than just ROM, because if this problem was present on all installations of these popular ROMs like Lineage, AEX and Pixel Experience (as I have tested in my own experience) then we would likely see a lot more complaints about it on the forums. So I think the issue is related to something to do with a certain setting or configuration.
It is a VERY frustrating problem because I can't leave my phone for 15 minutes without it disconnecting from WiFi and loosing access to notifications.

Not that this will help but in the past I had issues with Samsung OEM ROMs I flashed using ODIN (equivalent to our QFIL) a firmware from another country and for some reason even though technically my phone WAS compatible, I would have similar results to yours. If I were you I would back up all your data and try a few different QFIL to see if you have any luck. I flashed the LATEST QFIL (not using miflash etc) and have never had any issues with my zuk

Thanks for that. I agree it might be the cause of the issue, something like what you describe. It would make sense because I have only found 2 other people on XDA with the same issue, and the problem happens on every ROM I have tried. I have owned the ZUK Z2 since 2016 and only now, in these past 2-3 months, am I experiencing these problems with Wi-Fi disconnecting.
From what I can see the latest QPST is 3.5.389 ST, so I will try flashing that next week (once I'm back from vacation) and see what happens!

Well, I tried flashing the 3.5.389 ST QPST and then flashing LineageOS 16.0 on top of that, but the problem is still the same. Wi-Fi disconnects for a few seconds whilst using the device, and also whilst the device is in sleep mode. Except when it disconnects in sleep mode, it will NOT reconnect meaning I miss all kinds of notifications until I manually check my device.
The frustrating thing is I don't know for sure whether it's something to do with my home broadband or router. But all of my other devices (such as Windows laptop) STAY connected at the same time my ZUK looses connection. So I have to assume it is software-related on the ZUK.
If I can't solve this soon I will just go out and buy a new phone. I can't deal with missing important notifications. It is sad because I really liked this phone and have kept it for 2½ years. I don't understand why this problem suddenly started because it was fine before.

After you flashed the QPST did you boot into the rom and try using oem zuk to see if it resolved your issue? Apparently that fixes quite a few problems but requires actually booting into the rom. If you flashed an official QTSP using deep flash (not miflash) anf it STILL has that problem then it must be internal hardware. Guessing you have tried connecting to someone elses wifi and it does the same?

Thanks. Well, sometimes I visit a relatives house where I can connect to a different router, but usually I am not there long enough to test whether the phone stays connected. But in response to your other question, I did boot into the ZUI ROM after flashing the QPST. But I didn't test to see whether the problem persisted because I hate ZUI and could never use it on a daily basis when there are other, much better stock Android-like ROMs available.
I was in contact with someone else on XDA who had the EXACT same problem and he suggested trying the latest build of AEX which seemed to solve the issue for him. So currently I'm trying that but I haven't had enough time to test it, yet. So far I have not noticed the phone disconnecting but it has only been about 1 hour since I flashed the ROM. I will know more after a few days of testing.

Switching to AEX made no difference. Still no success despite wiping entire device and flashing stock ROM with QFIL. I have tried almost every Android Pie ROM including LineageOS, AEX, AOSiP and Pixel Experience. I also changed channel on my broadband router. Nothing works.

Then it may be a hardware problem, the antenna wires can be disconnected or damaged. Have you tried a stock Rom?

@1qazwsx4 @bordi21
After an entire year of this problem, I have FINALLY found a solution to my phone disconnecting whilst on home Wi-Fi. Turns out it is nothing to do with the phone or custom ROMs...
In the router settings there is an option called 'Enable IPv6 on LAN side' that is checked by default. I unticked this and now my phone is able to hold connection flawlessly!
