Why does the Internet die on the tablet?

Question

Computer networks

Given: a tablet for win10, TP-link routers. After a random time, it loses the Internet, the ping goes only to the router. If you reconnect to the network - everything works. Other devices on the same network and with the same OS version work just fine.
Question: Where to dig?

Answer 1

If everything is fine with the other router, change the router.
To remove encryption is to expose yourself

Answer 2

Look at the logs on the router and on the tablet. Usually, something like buffer oveflow error is written there. And it's so hard to understand why the connection is reset. And you can also connect the laptop directly and check if it is reset now.

Answer 3

try making a network without encryption. I don’t know what this is connected with, but after that I stopped losing the network.

Answer 4

strange. I often get this on my android tablet. but Windows never..

Answer 5

Is the time really random? view logs, update the firmware on the router.
