How block all other connections in my home wi-fi network totally in firewall

[Helius_Dev 0]

Hi dear managers,

It seems some malicious guys come to my pc through wi-fi router and delete all wi-fi logs in windows 10.

I am using Eset Internet Security latest version licensed.

How can i block all other connections through this network in FireWall?

I only need internet, Not else.

The ESET firewall protects only the device it is installed on. It cannot prevent other users from connecting to your wi-fi provided by the router; for this you have to set up your router correctly (change the default admin password, update the firmware, keep WAN access disabled, turn off UPnP, if not needed, use a stronger password, etc.).

Thanks for the reply.

I want config firewall to prevent access from other devices in in this wifi network.

For router i did your advice.

For block other devices what should i do?

Block an ip ranges?

When the network was detected, EIS used Windows settings by default. You can expressly set the network as "Untrusted network" under Network protection -> Known networks. Sharing, ping, etc. are blocked in untrusted networks.
