Help - Tab S2 keeps losing/freezing wifi connection

[lokoroxbr]

hi guys hwo are you?

So last month i bought my mom a Samsung Galaxy Tab S2 for her birthday.

But we have noticed some problems.

Everytime (almos all the times) she is using instagram to see the histories, or to see some video in facebook, her Tablet kinds loose wifi connection (the video freezes, keeps loading).

I already tried to disable "search for near by devices" and already tried to reconnect at wifi, to reboot tablet....

She has (i guess) the last software installed.

NOTE: THIS PROBLEM DOESNT HAPPEN ON MY SAMSUNG GALAXY S7 EDGE, ON HER SAMSUNG GALAXY J5 AND ON MY FATHERS SAMSUNG GALAXY GRAN DUOS (also doesnt happen on any notebook at wifi), only on her tablet.

Her tablet IS (we are from BRAZIL):

SM-T719Y
Android 7.0
Base Band: T719YDXU1BQF1
KERNEL: 3.10.84-11739684
COMPILATION NUMBER: NRD90M.T719YDXU2BQF6
Security patch android: july 1st, 2017
STATUS SE: Enforcing

Can anyone help me up here???? Thanks !!

Does this happen when using other apps like browsers, YouTube, etc. - apps that stream from Internet sources? Or is it just Instagram & Facebook?

she nevers uses youtube, so i really doesnt know. Is there a difference?

If so, why all other devices doesnt has this problem? only her tab s2?

Just wondering if it was isolated to those apps. WiFi problems can be tricky, with some devices working and others not on the same network. I got a new Dell laptop that had issues in my house where no other computer or device did - went away when I bought a new router (signal strength was not the issue). If she's using 2.4GHz, is it possible to try 5GHz? You can also use an app like WiFi Analyzer to look at signal strength as her S2 sees it.

Edit: Also, does the problem occur on any and all networks?

You can also try assigning a static IP address:

I own the SM-T713. I had this wifi problem in Marshmallow and found turning off "nearby device scanning" solved it. I upgraded to Nougat months ago, but have had no wifi issues.

However, other owners have been complaining and coming up with possible solutions on the XDA forum. This is one thread, but there are others: https://forum.xda-developers.com/tab-s2/general/tab-s2-wifi-issue-thread-t3450874
