I'm using GT P7300 (3G+Wifi) with ROM stock 3.2 (NO rooted). I used wifi connection at home for few hours with no problem. However, after I woke up my tab from sleep mode, if I wanted to go on using wifi, I always had to reconnect it although I already chose "Never" in "Wi-Fi sleep policy". That means when my tab is in sleep mode, there is no wifi connection anymore so can't push mail or online chatting during sleep mode.
After waking up from sleep mode, I see my tab still connect with the router (still see the wifi name) but the signal bar is in white color (normally it should be blue) and cannot use Internet. I have to reconnect wifi to make it work.
I also have Laptop, Blackberry PlayBook, LG Optimus but none of them get this issue.
Any suggestion? Tkz
Maybe its router security
Next to my galaxy tab we have a Zenithink chinatab which had the same problem. Forum told me this might have to do with your WiFi security.
I took there advice and switched my routers from WPA/WPA2 mode to only WPA2 mode. Never had the problem after that and it was allready like that when I got my P7310 and never had any WiFi issues with it either. Don't know how you configured your router, but maybe you have the same.
Also if you use MAC security, not all routers are as forgiving. So try turning that off to see if it makes any difference.
hi,
i installed cm11 and cm12 on my Motorola droid 4 and in both i have the same problem, when i use the wifi sometimes the internet stops in the mobile but the wifi is still connected, when i turn the wifi off and on again it come back. i don't have this issue with cm13 but android 6 is heavy on my mobile. i tried some solutions like delete /data/misc/wifi files and reboot, change wifi advance settings, nothing works.
when i download my apps from the store randomly the internet stops but the wifi keep connected and sometime it come back by it self, but mostly i have to turn on and of the wifi or reconnect again to the network.
also i make factory reset before install the rom, i used these roms (cm-11-20150201-NIGHTLY-maserati.zip, cm-11-20150901-SNAPSHOT-XNG3CAO3G0-maserati.zip and cm-12.1-20160120-NIGHTLY-maserati.zip)
is there any solution for this issue? please help.
thx
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
I have Moto G 2nd gen (xt 1068) running on official Android Marshmallow 6.0. My phone is not rooted nor I have installed any custom ROM.
The problem with my device is, it's battery statistics shows that WiFi is ON even if I turn it off from phone settings and also from scanning settings.
I think this 'always ON' WiFi is also draining my phone battery.
Idk if there's any app who is using WiFi or not and if yes then Idk how to know which app is it.
Any kind of help will be appreciated.
ps. I barely use WiFi for internet access, I prefer mobile internet.
Hi everyone
I have a profile that that kicks in every 30 mins from 8 am to 9pm, to sync my account. I have set it up to use wifi first, but if there is no wifi connection it will go to my mobile data instead.
Now here is the problem if my phone is on standby it always connects via mobile data regardless of a wifi connection is available. But if I am using my device at the time when the task runs then it will connect to wifi. I have checked my, keep wif on in sleep option and it is set to always.
Could anyone explain as to what this is happening?
Thanks in advance
What is your Android version?
I am currently using a custom rom called exodus which is currently based on marshmallow.
Check if Tasker is excludied from Battery Optimization and whether Wi-Fi is not deactivated while the phone is in sleep mode in Settings/Wi-Fi/Advanced/Keep Wi-Fi on during sleep.
yep tasker is excluded from battery optimisation and the allow wifi during sleep policy is always.
If you're turning wifi on with tasker action wifi turn on, try instead of that shell script "svc wifi enable".
Ok thanks, I will let you know the out come of this. I was using secure settings to enable Wifi as the command built in tasker, is not compatible from kitkat and onwards if I remember correctly.
I found out "svc wifi enable" command does exactly the same thing
Discovered I'm having the very same problem on cm13 and the batch jobs have been done by initialized mobile data. Finally found out a solution to initialize wifi instead of mobile data. I've no limited data plan, but wifi is more battery friendly.

Do you actually wait for wifi to connect?
Does your phone do the low power screen off wifi thingy?

Yes under normal circumstances it takes about 20 seconds to connect.
No because for some reason my wifi will only switch on if the screen is on.
I also have uninstaled my custom kernel, but this issue still appears from time to time.
There's a setting in wifi connection settings that you can set to that says "keep Wi-Fi on during sleep"
This same setting is often repeated in battery apps like powernap, naptime, better battery saver etc.
Even though the wording is the same, I don't believe they are all touching the same setting so go find those apps if you have them installed.
Also, disable all native battery savers (including Samsung 2 or 3 different ones,, doze, battery optimization etc etc just to see if your problem goes away.... Which it will. At least you'll know though
I have the same problem with Wi-Fi connection.
I have a profile to turn Wi-Fi on and try to connect when certain conditions meet and the screen is off in that case.
It seems that the phone has difficulties turning Wi-Fi on and connecting to it when screen is off. Tasker does manage to turn Wi-Fi on but the phone somehow does not connect *reliably* in all cases.
Tasker is excluded from battery optimization, Wi-Fi on during sleep. I tried turning cpu on for a short time hoping that it will connect, but still no result.
The only possible solution might be turning the screen on briefly at that moment.
If anybody has a better idea, you are more than welcome to share!

I can certainly say that turning the screen on will enable wifi, as I have resulted to this as well. But unfortunately I do not know any other solutions to try.

My Wifi is set to always "keep wifi on during sleep"
I'm going to resort to flashing stock rom again and see if that helps. As I am only using doze and amplify to save battery, all settings for that has been adjusted to the guide I found.

Before reflash, just disable xposed and see what you get... I will bet half of this soft taco I'm eating your problem disappears with greenify and or amplify. I'm not saying don't use them at all... Just make sure it works without them. I used to have some serious battery apps, but found after disabling, my battery was IMMENSELY better. And I had no config to deal with. But first things first... IT'S without a doubt, no question, a battery app setting or a system app that's being put to sleep that should be white listed
