You can set up a wireless router in Client Isolation mode. This blocks
traffic between wireless users. You will be separated from your house
mates and won't have to mess with any domain setting. I'm not sure if
all routers have this feature, but I'm pretty sure the Linksys WRT54
series does (or if you use a 3rd party firware you most definitely will
be able to enable it).

Also, like a previous poster mentioned, if you use a firewall to block
all traffic from the local network (most good firewalls allow you to set
address ranges in the blocking rules) your house mates will not be able
to access your computer (nor will their viruses).
