Why is the computer not visible on the network and at the same time the Internet is in it through the LAN router?

Answer 1

Firewall, for example.
Often on a Windows PC, you need to add the PC to the homegroup and allow it to be discovered, otherwise you won’t even be able to ping.

Answer 2

1- You need to transfer the network connection from a public network to a private one.
2 - Make sure that the permission to discover this computer on the network is enabled (as colleagues described above).
3 - make sure both computers have the same workgroup.
