Samsung Tab S2 SM-T813 wifi authentication keeps failing after latest Android upgrade

[DocFar]

As soon as my tablet updated to Android 7.0 Kernel 3.10.84-14953299 it keeps dropping off my wi fi and giving authentication errors .

It was working perfectly well before

A Samsung note S9 right next to it has no issues and the same for all my other wifi devices

Any suggestions - other than hard reset??? I would hate to do it and then find I still have the same problem

I've had a new processor, new screen, new power port, software replacement. My TabS2 is still *****e. A 9 year old can see it's not working properly, but not Samsung.

At least you got 18 months. My TabS2 hasn't worked properly since I got it. A 9 year old can see it's not working properly  but not Samsung engineers.

Absolutely a problem I continue to experience  Samsung blame my WiFi, but it drops other connections.

My TabS2 is also unresponsive, sluggish and hangs regularly. Utter *****e.

I have the same problem. 

I have the 4g so the internet is not gone. But when I try to cast movies to my TV then I noticed that it have no connection to any WiFi. Turn off and on the WiFi button and it connects to my WiFi again.

A have a Asus Lycra Mesh WiFi. 

Now that added some Sonos speaker it would be greater to have the Samsung Tab S2 SM-T819 be able to keep the WiFi connections.

Do you have the latest system updates installed? Mine started working one day just as silently as it quit working. I suspect that a system update quietly fixed the source of the problem. I've had no issues for the last three to four months with it dropping the wifi connection.

Thank for the tip. But I have the latest update according to Samsung.
