Wifi keeps dropping out all the time - Samsung Galaxy A70 Questions & Answers

I've been having problems with streams dropping out, WIFI calling dropping out, games dropping out, etc, turns out that is all caused by the wifi on this A70 dropping out. It seems the more demand I place on the wifi, the more likely it is to reset. It drops the wifi, switches over to LTE (making me use all my data) for about 10 seconds then the wifi comes back. I just upgraded from a Note 4 that never had this problem so it's definitely not my router.
I've tried every setting I could find, from turning off the "switch to LTE if wifi unstable" to the hidden "wifi safe mode" setting in Developer Options. Nothing makes this wifi stable.
These drop outs happen no matter the signal strength - I've seen it happen 5 times in a row when I'm at full bars/-55dB, right next to the router. Does anyone know of a fix for this?

hear hear! same here...wifi on this phone is simply awful...it makes surfing almost unbearable on a70...it drops connection with wifi all the time, switch to data and comes back to wifi many times a day...it seems samsung is trying to hard to make wifi smarter than usual...it shows checking quality of your connection, please, don't check anything just let me use any wifi with decent signal! i can't even describe how frustrating it is!
at the same time mine old lg v20 is still working perfectly on wifi 24/7 without single problem on the same network...

Do you have the A705w (Canadian) A70?

no, i'm in europe...

I have this same problem
Not know solutions ??

I have this model. I haven't had any problems that I noticed. At home I use N WiFi on 2.4. Seems ok at the office, haven't checked if it's using the 5 band there.

Maybe i can change same in config WiFi but who ?
I have root

I'm in UK and no WiFi problems with my A70 at all.

No problems for me also, home wifi and free hotspots at work and town works perfectly. EU country.

I also have this problem. I notice that when I start playing any games that my wifi just drops and disconnects. Maybe it has something to do with the latest update. What ever it is, I hope we can fix this soon

after november update wifi is acting up again...it drops connection every once in a while...

WiFi issues?

Not sure if it's just me, but WiFi will randomly disconnect every 5-10 minutes for a few seconds, then reconnect itself. My m8, nexus 5 and nexus 7 2013 are not suffering the same so I'm assuming it's not my router. Anyone have any thoughts?

I think the range is weak in my house my 5ghz on my s5 was 585mbps and my g3 is 296mbps but wifi works great but in my job We have like 5 differend ssids and they all disconnect alot and they all different routers but I guess in my house being closer doesnt log off but at work it does
guys chill! you dont have any problem with your wifi. our phone is looking for a better signal, if it doesnt detected that you have a poor connection it will disconnect itself and it will toggle on your cellular network.
here is your solution
go to your wifi click settings > advance wifi > and uncheck Wi-Fi signal weak and bam. you have your wifi connected all the time!
hit thanks will ya?

Lol same problem s5 wifi signal os stronger on same ssids
I also have this problem and I decided to debug it.
With my jabber client which logs every disconnect I found out that it disconnects from wifi every 5 minutes.
So I opened my router settings and found that only setting that is set to 5 minutes is interval of "Group Key Update". So I changed it to 15 minutes and now it disconnects every 15 minutes.
So it's not solution, but only a workaround. So i will set it to few hours and hope that LG will fix it soon.

Wifi Drops

Had this tab for about a month and since day 1 ive been having wifi drops.
I thought it might be my mobile hotspot or home network, but compared to other devices i know its not.
This is the only device i won out of 30 that does this.
ill be on the network and all of a sudden i lose connection and then it starts up again.
i tried changing the channel on the network and still a no go.
i thought of rooting it but really wanted to just keep it stock.
If anyone knows of a rom that would fix the wifi drops 100% then id consider rooting.
please help

I have the same experience.
I have a T320 (8.4" WiFi) which I had rooted using the Towelroot method, and I kept getting the "Now connected to... [router]" reconnects even when I was sitting right in front of my router.
I found that by keeping "WiFi Always On" (which I believe was the default?) during sleep instead of "only when plugged in" or "never", those wifi drops are less frequent, but still an annoyance.

Hopefully your issue isn't as serious as mine is. I literally just got off the phone with T-Mobile and they will be sending me a replacement phone.

I had this issue with my first G4, but i sent that back due to damaged leather back i have had a couple times with the second one where the wifi acts funky, not a problem but def like wtf moments
No problem with disconnects here.
Mine definitely disconnects and reconnects randomly
My verizon g4 disconnects periodically. Should I be ordering a replacement?
I haven't seen this with my H811 G4.

Only had the phone a day so haven't seen this yet but i did get it randomly with my G3. I could never figure it out. A quick on/off of the Wi-Fi fixed it quickly. Router is Netgear Nighthawk. About 8 other Wi-Fi devices in the house and never seen it on anything else.
I've been seeing this on my H811. It's nothing major but it does cut off then quickly reconnect after several seconds.

Mine also does this on the T-Mobile version.
H810 here. My G4 seems to strongly - and I mean really strongly - favor mobile data. My house is festooned with wifi access points and yet my G4 often turns its wifi radio off and I have to manually turn on wifi, then manually connect to a nearby access point. As I move through the house, rather than connecting to an access point with a better signal, it shuts the wifi radio off, altogether.
The G4 has shut its wifi radio off while I've been in the process of selecting a wifi access point. It's shut its radio off right after I've selected the access point I want and while I'm booting up the web browser.
Today, at work, the G4 is continuing to seemingly randomly shut off its wifi radio. When I manually turn it on, then select the access point, I find the phone has forgotten the password.
Very frustrating.
As an experiment, I have now shut off mobile data, to see if that will coax the G4 to seek and maintain its wifi connection. But there's no way I'm going to spend my day turning off or on mobile data, wifi radio, etc. I'm already manually turning Location on and off, to preserve battery power.
had wifi issues on the 2 g4's i've had. sent first one back due to damage to back cover on arrival. Glad its not just me having wifi issues
Having these issues as well. Rebooting my router sometimes stops it from happening, but quite frustratingly, the phone gets very hot (and discharges quickly) as a result. Have had a hot, dead phone before.
Most of the WIFI routers have different type of connections G / N / B, The N type is not a !00% compatible with our G4, therefore I suggest you to change to B/N, after I change the protocol, I havent see the WIFI issue so far.
I had Wi-Fi disconnects because I had turned on the advanced option to automatically swap to Mobile data on weak Wi-Fi signal. After that was turned off, the Wi-Fi worked as it should.

I found that disabling ipv6 on wlan0 fixed my slow wifi issue, but still getting the disconnects. (it reconnects automatically though)

Every instance of SManager is my wifi reconnecting randomly in the house yesterday at my desk.
I have had this issue on my H811 since new. It does it more on 5 Ghz than on 2.4 Ghz, but it still happens. It's more common at home with my Asus router than at work with the Cisco APs they use.
After the latest update I have noticed that the iPod touch I keep in the car disconnects from the hotspot on the phone way too often. This never happened with the previous build, but I also didn't have xposed installed before. Has anyone else noticed any issues with their hotspot?
I got an LG G4 on Friday in the UK and it is running version 10D.
I am encountering this issue and I am finding it extremely annoying - did anyone find a resolution?
It is so frustrating it is getting to the point where the phone will be going back for a refund. It does it at any location with WiFi I go to, so I know it isn't a configuration issue on my WiFi at home.
I'm having this issue too all of a sudden. First thing I noticed was excessive battery drain. But every few minutes it connects to a different ap in my house. Other phones and devices don't do this. Time to dig.

Anyone else having WiFi randomly disconnect and reconnect?

I just got this phone yesterday and so far I just cannot get it to stay connected to my network. No other devices are having this problem. It basically just seems to constantly connect and disconnect from the wifi and also seems to constantly search for other connections as well. I've tried factory reset, cache clearing(which never works as it just red triangle error's me), reset the router, tried to change settings in phone itself but nothing seems to fix it and it's making it impossible to use at home. Anyone have any suggestions?
Same thing here. I went in and turned off all the wifi in battery power saving exclusions. Ain't been home long enough to try though.
I'm having this same issue! My prior daily (S9+) didn't have this issue, and my Pixel 2XL doesn't have this issue. I could be right next to the router and it still does this. Doesn't seem to matter if I'm at home, work, parents house, or a cafe, it still randomly loses connection. Same with my Gear S3. Just randomly loses connection. It's pretty annoying, and I hope they offer a software fix. Yes, I factory reset the phone and it still occurs.
I noticed this only with the 5 GHz band... I will contact LG about it today...
Yeah, I'm having the same issue. My router broadcasts both 2.4 GHz and 5 GHz on the same SSID. Last I'd heard, Android wouldn't connect to 5 GHz in that circumstance, and my G7 appears to continue that trend.
But it still disconnects from the network all the time.
Sadly I have the same issue. I have different SSID for 2.4 and 5Ghz band, and as devil_tear says it's fails only with the 5ghz band. I did a factory reset but issue stills there.
Did you found a fix for this issue?
Had the same problem. Solved by enabling wifi on the battery saving power exclusions in the battery menu.

Thanks a lot for this tip.
Had the same problem, was burning through my 4G data at a rate much faster than on my Google Pixel.
So far, adding wifi to the power saving exclusion has seemed to fix the issue. Thank you!
PS: Does any else find the wifi signal on this phone is weak?

Great suggestion
Tried the suggestion here for adding WiFi to exclusion. WiFi on 5ghz still disconnects and reconnects every few seconds. Only way to keep it connected is putting it on 2.4ghz.
Tried the suggestion with reboots, factory reset, adding WiFi to exclusion and then connecting to the network. My g7 will just not work with it.

Have seen this also, in my case it happens when I am a bit far from the router, it may be the router not having a strong stable connection so the phone see it doesn't have internet. In the points I experience that I have a 5Ghz connection of 0-2Mb but I have maybe 2 bars of connection. Share your opinions to try to understand the problems.

For me I would say it happens more if I have 2-3 bars but nonetheless it happens even 3ft away from the router eventually. what's odd is my note 5 stays connected, my computer, and other phone stay connected on the 5ghz band. All these devices are in the same location so I'm pretty dumbfounded especially considering this is a newer phone than the note 5 lol. I hope it can be fixed with an ota update

I have the same issues. I sent back the first phone for a replacement thinking it was the issue. When the second phone arrived it was working perfectly and then it happened again.
I noticed this happened after I took whatever software update was offered. I went as far to switch providers with different equipment (fibe to cable) but same result.
Made specific 2.4ghz SSID for LG G7 and no issues.
I've never seen this happen. And my laptop and LG are using the same 5 ghz signal.
I think I remember the G6 doing this though

Just came back from my dad's house and I know it's a short test, however he has an Archer a7 connected after his dedicated provided box. I wonder if that can fix the issue?
I have the same issue.
it connects to 2.4Ghz networks fine but the range is very limited when I move to another room wifi reception decreases a lot. However my wife`s S9+ and my oneplus 6 works fine.
Main problem is when I connect to 5Ghz network it starts disconnecting and reception is even worse than 2.4Ghz. S9 and Oneplus connection is still fine at 5Ghz
I tried to change the 5ghz channels on the router but no luck and I exclude the WIFI from battery saving apps still didn`t work.
I have to use 2.4Ghz and the reception is not as good as other phones
Wifi seems stable for me, except wifi calling. That would crash at connection or even mid-call sometimes. I'd have to reboot to make or receive another call. Some sort of server error. Turned off wifi calling and no issues yet. Didn't notice Ed it anyway since 4g is really strong here.
After the newest update on my phone, taken today Oct 4th, 2018/my random WiFi disconnects haven't been happening at all on 5ghz. Also, the signal is about 3 bars larger now in the same location it used to be dropping out constantly. Hopefully it stays this way.

I was coming in to report something similar. I've got the US T-Mo version and just got the G710TM10K update yesterday.
WiFi stability has massively improved. Disconnects are almost completely nonexistent now. I haven't noticed that the signal bar is behaving any differently, but that doesn't mean a whole lot. The update was fairly large (over 400 MB), so I could see new firmware playing a role.
Could anyone still on G710TM10G post their data from Software Info to check if the baseband has been updated? Here's mine from 10K:
Android Version: 8.0.0
Android Security Patch Level: September 1, 2018

Question WiFi problems - Do others see them too?

Hello Folks,
In summary, the WiFi stack on OnePlus 11 is quite unstable compared to other smartphones (that are also based on Qualcomm SoC with built-in modems).
First off, I've two 802.11 AC (WiFi 5) routers. Compared to my Asus (ROG 5) and Motorola (Moto G 5G Plus) phones, I've noticed that my new OnePlus has better reception for both mobile and WiFi networks. E.g., at the same location where ASUS has say -30db signal, OnePlus 11 shows -27 or -28db. So performance wise, it's fantastic, however, stability of WiFi connectivity is subpar. Between performance and stability, obviously I always prefer stability. I've up-to-date OnePlus 11 CPH2449 device (CPH2449_11_A.08).
I've been using the phone for about 5 days & these are the three distinctive WiFi problems with OnePlus 11 that I've observed in that duration:
1. WiFi dieing silently:
I've seen many times that all of a sudden the WiFi symbol will disappear. Then checking the status of the connectivity will show that it had silently dropped/died. Sometimes, it'll reconnect on its own within 10 odd seconds. When it doesn't, then toggling WiFi off and then on may help. When even that doesn't help, then toggling airplane mode on and then off becomes necessary/only-way to re-establish the connection. During these episodes, the phone is barely 2 metres away from the routers with a clear/unobstructed line of sight with them. Needless to say, neither ASUS nor Moto exhibit this problem while these episodes are playing out with OnePlus 11.
2. VoWiFi dieing silently:
While operating the phone (non-phone-call situations), a number of times I've seen that the VoWiFi logo would drop and VoLTE logo would appear. Interestingly enough, within a matter of 10+ odd seconds, it'd re-establish the VoWiFi connectivity on its own.
3. WiFi not roaming efficiently:
When moving faraway from one router and close to another, it doesn't roam to the closest one, instead holding onto the furthest one. But putting the phone down for say a minute with the screen off, triggers the roaming to the closest router! WiFi assistant neither helps nor hinders this behaviour.
In short, it'd seem the whole WiFi stack is riddled with stability issues. I've done "Reset Network settings", which didn't help with those issues.
Am I the only one facing these issues?
Thanks for any help/guidance.
Wifi Issue
Anyone have wifi dropping off and reconnecting after flashing to oxygen os? I seem to keep experiencing this. Anyone have any fix?
forum.xda-developers.com
No issues with Wifi.
Just downloaded over 130GB over Wifi and ftp server on the phone without a single interruption. Took over 3 hours and no problem.
I have similar issues. My wifi will randomly drop out and then pick up again in that time sometimes it will say internet offline. I've been noticing it the last week or so when that happens.
I've escalated my problems to OnePlus support. After a number of discussions, I think we got the winner: Disabling ipv6 in my WiFi network seems to stabilise it!
I've been trying this only for the past few hours, but it's proving positive so far. Still I'd prefer to test this over at least a day or two.
I've had WiFi just stop working finds no networks. Even turning the toggle off and back on again doesn't work. But after a reboot works fine again. Mines a euro model on fw09

I've seen similar behaviour. Turning flight mode on and then off helped me on those circumstances. Mine too EU version CPH2449.
Now, if the root cause is identified and addressed, then it ought not to even regularly disconnect from WiFi in the first place, so subsequent problems like reconnection issues can be avoided then.
Disabling ipv6 has proven to be a good workaround for vastly improving my phone's WiFi stability. Of course, they need to identify and resolve the problem that's making WiFi & ipv6 incompatible though.
