How to ping from tablet to laptop and vice versa?

Question

Computer networks

The home network diagram is as follows: there is a router with the address 192.168.1.1, there is a computer connected to the router via an ethernet cable with the address 192.168.1.102, there is a laptop connected to the network via wi-fi with the address 192.168. wi-fi with the address 192.168.1.101.
I am able to ping between any two devices, except for a laptop-tablet pair.
Proven non-working options:
- disabling the firewall on the laptop
- disabling AR isolation in the router settings (it is disabled by default)
Tell me, what could be the problem?

Answer 1

Put wireshark on your laptop and see if packets come to you in principle. Perhaps AP isolation works the way you would like it to.

Answer 2

The tablet cuts down Wi-Fi in standby mode.
