Hi all , I have the tab s2 813 model , I keep getting the notification of " connected to WiFi " on the screen whilst watching streams on my tablet then it cuts the stream off and I have to reconnect , its like it's dropped wifi and reconnected , anyone else have this problem , many thanks .
I have a 8 inch variant with marshmallow amd particular in airplane mode the wifi connection is flickering like you described. In radio mode the wifi is stable. Model no is SM-T719
When you say Radio mode do you mean just wifi

I mean the opposite to airplane mode, you know like normal phone mode (LTE /4G).
Ah right , mines wifi version only , I've actually got it on air plane mode now so I'll see how it goes , thanks
Currently no big issues anymore. Looks like Wifi on airplane far more stable. Dont know why..
Same with me , turned off air plane mode and got " connected to WiFi " notification flashing up regularly , put back in air plane mode and seems way better , weird eh
Thanks for the heads up about putting it in air plane mode , didn't even think about doing that , cheers , you're a star
Keep your hands out of the SM-T719 Galaxy tab S2 variant.
I bought one for Christmas, 2 days later I replace it in the store, and then I replaced it again by a third one. BUT... the third one is no better.
All start in the setting up phase, for the first time, since the device has difficulties to connect to google and Samsung servers. Then comes the first firmware update where the download process stops without reason countless times. I have to turn WiFi off and on to be able to proceed. Finally using Playstore and mainly the "Galaxy Apps" application I get too many errors about java.net.... address unreached, no route, server fail, no internet connection make sure WiFi or cellular data is on.
The problem seems not to be in the WiFi losing connection, the WiFi is always at maximum or medium, but somehow the internet access is lost, and when lost is not recoverable by the app, unless I completely close the app, turn WiFi off and on... sometimes I need also to restart the device. Unacceptable behavior.
Now, by Samsung advice, I'm going to leave it in a Samsung repair center, and since I'm not convinced that they will solve the problem at all, because the problem is random and even if they change the board the problem is in the guts/design or whatever... of the device, I'm going to return it to the store and get the money back.
Since i put mine in airplane mode the wi-fi notifications have stopped and never had any other issues with it , mines an sm-t813 , think it's just that it's the 9.7 rather than 8 inch

I have the same issue with my two SM-T813.
The wifi keep disconnecting and reconnecting randomly on 2.4ghz wifi connection. When this happen, a toast notification appears saying you're connected on your wifi. This happen to me on every router i'v tried with many firmwares.
No issue on 5ghz, see this https://forum.xda-developers.com/showthread.php?t=3414419
Wow , thanks for the link , i couldn't find that link when i first posted , mines been fine with airplane mode on , no drop outs or " WiFi connected " notifications so I'll leave it alone unless Samsung update it but can't see it happening tbh

OK, but that behavior of your device is unacceptable... having to keep your device forever in airplane mode....
As far as I can tell about mine SM-T719, WiFi is never lost, there is NO notifications about the the system loosing WiFi or reconnect to WiFi, and I can see that WiFi is always on maximum. However, the internet access drops randomly and the application accessing internet cannot recovery from it without turn WiFi off and on again. But the WiFi signal keeps on and well during the occurrence. How odd is that?
My WiFi signal was always showing strong but when watching a stream on my tablet the notification would pop up and the stream would go off then I'd have to reconnect
Wifi dropout

I have a new tab S2 SM-T713. I've had it for about a month now and when I'm downloading apps the Wi-Fi drops to zero and won't pick back up without restarting the Wi-Fi. Does it constantly no matter what network I'm on. At first it started with the Wi-Fi switch not staying on so I flashed a permissive kernel and that gave me the Wi-Fi but it has done that ever since no matter which kernel I use or which ROM I use even stock ROM.
Try putting it in airplane mode and turn WiFi back on , see if that helps
Hi,
My Note 5 (SM--N920W) recently started to switch Wifi, on/off intermittently. Sometimes, the Wifi stays on for 15/20 minutes (like when watching youtube) and some time it turns on/off continuously (mostly, when downloading a large file with a continuous stream of data). I can see that in the phone settings, the Wifi button goes grey (to off position automatically) and turns blue automatically & tries to connect to the router, sometimes it stays connected for some minutes and sometimes it's just instantaneous that it goes grey again (Wifi off). This keeps on repeating.
The phone is updated to Android 7 (official ROM) and has been reset and also tried all different settings like turning off location completely, disabling wifi scanning etc but that didn't help. Any idea what could be wrong? Also, the phone is locked to a carrier for which I don't have the sim anymore. I am not sure if running it without sim is causing this wifi issue.
Thanks! Any help is highly appreciated!
If you can try using a different wireless router or network, and see if the issue persists. I had a similar problem awhile back, except it only happened when Bluetooth was on. I ended up buying a new router instead of the one I was using from Comcast, and it resolved the problem! Also I've similar issues with other devices, and editing the build prop and changing ro.securestorage.support=true to false in /system/build.prop might help.

Thanks a lot for the reply. I'll look into secure storage flag, though it looks like this is for the rooted devices, mine does not seem to be rooted (I bought it online, not sure if that was rooted earlier or not).
Another behavior I have noted, that initially the wifi for first few minutes works ok, no drops or switching on/off. But then it starts to go nuts turning on/off continuously. I am not sure if its a hardware issue, that somehow the wifi module gets hot after a few minutes of usage and starts to malfunction. But I have read somewhere on this forum, that the BT & WIFI are on the same module on the motherboard if the BT runs fine (which it does on my Note5), WIFI as far as hardware is concerned should be OK.
I haven't tried any custom ROM (though tried downgrading to Android 6.1 - ROM from sam mobile) but that didn't work. Any idea, which custom ROM is most stable and easy to apply?
Thanks!
If your on a stock unrooted rom, I'd definitely try another router, even if your just connecting to a friend's. If it doesn't occur then, its the router. As far as custom roms, I'm running the Note fan edition port by RadeonMaya, and it works great.
Im turn WiFi every time ON per Wifi disonnect or lose intensity. Im turn ON screen and WiFi connect/intensity up
Settings - WiFi - Settings icon - Wi-Fi always ON during sleepmode: ALWAYS.
PD: Sorry my bad english
¿solutions?
PD: use b156 patch1
EDIT:
I think I have found the problem. Wi-Fi+ activated. Turn OFF
No. Huawei has completely buggered the wifi implementation. It is easily the worst I have ever seen on a modern phone.
I have access to conformance test equipment as part of my daily work and so I have tested some more difficult to pass test cases.
The P20 pro fails nearly all wifi alliance handover tests that I have checked.
For example, when you are on a cellular connection and then you access a wifi network which requires a login, like at an airport or McDonalds, the cellular connection must be kept until a data connection via wifi can be positively initiated.
The P20 does not wait. You can see that it performed a PDP context deactivation on the cell side and trys to use only wifi. Fail
I have the same issue. WiFi is set to not sleep with screen off, but if I'm streaming from my Plex server over WiFi, it always cuts out after a couple of minutes after the screen being off.
What do you mean by "Wifi+ activated"? Where do you turn that off?
I have the same problem and it really sucks.

The only solution is to get a different phone. Huawei has completely F'ed up Android with their EMUI nonsense.
Hi community,
I'm writing because I have a strange WiFi problem with my S21 Ultra which I had with no other equipment before.
Setup:
- Galaxy S21 Ultra
- FritzBox 7590
- Fritz WLan Repeater 1750E (2x for better range coverage)
- WiFi 5G Auto channel WPA2/3
- WiFi coverage is good (tested with a lot of other devices)
Phone Setup:
- Paired with the WiFi
- Do Not use Mobile Data
- automatically reconnect to wifi
Problem:
The phone does not automatically connect to the WiFi.
The phone also looses the connection to the WiFi several times a day.
When the phone is not connected to the wifi I open wifi settings.
- It happens that the wifi list is completely empty and the circle animation indicates that the phone is searching for nearby connections
- It happens that the wifi list contains a list of wifi networks the phone has seen before when it was connected last to a wifi
- Switching off an on the wifi helps to find the actual networks and the phone then connects back to wifi (most of the time)
I tried already several settings and combinations but so far none of them brought any success. So I would like to know if someone else had a similar issue or has an idea what could go on here.
To me it seems strange that the wifi scan is not working as I would expect it. I would expect the phone to continously refresh the wifi list with networks it sees, but always when the phone lost its wifi connection the list is not working anymore.
Try tinkering with the wifi channels and encryption until it shows up.
Or you can try resetting the routers to see if it does anything

Has anyone else have WIFI connection problems ? With not finding any WIFI until i factory reset it? And after a few days the problem reappears. Last time i didn't factory reset it and after 3 days, with no adjustment, the phone found WIFI, but...

You said the phone loses connection and etc. Does that happen only at the location you described, or does it also happen at other locations?
It is possible that your phone also gets confused with the router and the repeater.
1st you need to clearly understand if the issue comes from the phone or possibly from your WIFI devices. Once this is clear, you have something to go on with...

- Phone is on standby (placed on a table, etc.)
- I turn it on to check messages,
- No connection to wifi
- Open wifi manager
- No wifi networks listed at all
I do not know why my router/network should be the problem. All other devices in the wifi work flawlessly. It cannot be that I have to restart my wifi router every time the phone finds no wifi at all. That makes no sense to me.
It looks more like the android wifi service is still on sleep and does not report new wifi networks (which would be necessary also to see any wifi at all).
May I suggest....
Settings -> Connections -> Wi-Fi -> (three dots it top right) ->Advanced
Make sure "Turn on Wi-Fi automatically" and "Wi-Fi power saving mode" are both off.
If you use a repeater is it a mesh or AP solution? I find Android will drag its feet letting go of a wifi signal even when walking into range of another known network. Had an extender in garden and even when down to 10% connection on Wi-Fi it would stay connected to extender, I had to turn wifi off and on quickly to get it to pick a better network.

It seems to be the phone...
Definitely try what lywyn suggested...
you can also submit an error report on Samsung Members app, it sends reports directly to Samsung and get the feedback.
Download the app from the Galaxy Store if you don't have it on your phone > Memers app > + button > Error report

Unfortunately no success. I configured exactly like suggested. Does the S21 Ultra have problems with handover in meshed WiFi setups?

Never had any problem with my S21U (Exynos) with my Mesh WiFi (Deco X60) setup.

sometimes it happen when you connect at certain locations.
If you haven't already done so give this a try. Settings, search "Wi-Fi", scroll down to Location, Improve accuracy - toggle on, Wi-Fi scanning - toggle on.

Mesh is a single network solution so should not be a problem.
The only other thing I can think of is the power-saving mode. My son has his Pixel on power saving all the time and I know sometimes he has to turn off/on wifi to get a connection when waking the phone up
I found the issue! It is WiFi Direct related. The app "nexar" from the dashcam is interfering with normal WiFi on this phone. Nexar conquers the WiFi functionality and is responsible for my wifi disconnecting. The app requires the "Location always" permission. If I remove this permission my WiFi works again normally. So: one has a similar issue: remove "Location always" permission from the nexar app. In my case it helped.
You said the phone loses connection and and many others. Does that show up best on the region you described, or does it also happen at different places?
Kodi nox
It is feasible that your phone additionally receives harassed with the router and the repeater.
1st you need to honestly recognize if the issue comes from the cellphone or likely from your WIFI devices. Once this is clean, you've got something to go on with...
Hay guys,
I am really at a loss, so I hope you can help me here.
WiFi on my phone works totally fine until I install the EMUI Update 10.0.0.185 (and later).
From that point on, I can't use my WiFi at all. The Phone is still showing me a list of all the available Networks, but If I want to connect to one of these, the phone's WiFi turns off by itself. Just du turn itself on again a few seconds later... and turning off again eventually.
This happens to all of the WiFi networks, I've tried. Also I can't setup a WiFi hotspot anymore or use wireless display feature.
If I reset my phone to the EMUI-Version it came with, everything works flawless.
Any idea, what could cause the problem?
