user9fQeFM2Vww is right about using the 2.4 GHz network.
I told my unit to Forget the 5 GHz.
I have tried all of the suggestions here and else where, short of a factory reset. - not the problem
Even removed the Magnetic Sammy mag cover as some others else where suggested. - not the problem
I went through 5 GHz channels 35, 40, 44, 48 at 20-40-80MHz Channel Width - no go
Stayed from the DFS-channels which are basically every channel from channel 52 and up.
5 GHz worked for about 2 months when the unit was new - not any more.
The unit for most of it's use is 10 ft away from the route - direct line of sight.
No other device in my house has this problem. Not enen our Galaxy s5 or Sammy TV.
This seems to be a SAMSUNG problem on a lot of their devices for a long time.
No wonder I've never had this problem, I've never connected to my 5 GHz network. I'll be sure to have the tablet forget the network.
This begs for a MASSIVE recall, but unless our batteries catch fire, Samsung will undoubtedly try to sweep it under the rug.
Thank you Wi-Fi Alliance for the certification. 😉
In all fairness, I believe the link to the solution should be directed to one of the posts clearly showing the problem has always been a wi-fi issue, and NONE of the troubleshooting routines seem to do any good, as this is clearly a Samsung inherent issue.
i just stumbled across this post, our Galaxy Tab A 8 in does the exact same thing. Random reboot/shut off. Doesnt matter how much charge it has. Ive done a factory reset from the recovery mode and its still an issue. Im going to try the wifi fix and see if it corrects. ours never did this until the most recent 6.0.1 update....
Yes, going from my 5g WiFi to the 2.4g WiFi resolved my problem. My Tab A has been up for almost 2 weeks now without powering off. Before it was happening multiple times per day.
