My roommate and I use the same network. Problem is he has no respect to security he originally wanted to have the network unlocked but after a long time I convinced him to lock it.
But now he doesnt even care about his computer he has no antivirus no firewall and uses pirated OS and programs. I am using ubuntu and I have hundreds of euros worth of work saved on my computer and I am worried for an attacker on his computer can gain access to mine. I looked into my router configuration there is a "Isolate wireless" button but no description or anything does that close multicast or what.
Is there a way to isolate his computer to the rest of the network? Or is there a way I can convince him that using pirated OS/software is bad for his computer and the network overall?
I am using a netfaster IAD router and has most advanced features(except VLAN)
