Isolate Offending System on WIFI Network?

• Hello, I was wondering if it is possible to isolate a problem system on a network. I have one user that may have a system that contains malware or that they connect to sites that could contain malware. I do not want his system infecting the rest of the network or any devices or systems that connect to the network such as iPhones, laptops, etc... I understand I could mac filter his system on each of my devices, however, I was wondering if it is possible to isolate his system so that he can only connect to the internet but not any of the other devices using the network? I don't know if this would require some sort of domain scheme or something else, however, any input would be much appreciated.

• Answer:

  This can be done easily with managed switched and advanced managed WIFI routers. Each switch or router will cost you at least $600. Why not just clean the problem system and install good antivirus/malware software?
