Hehe, I'll check it out. I'm having a problem, though:

My roommate unplugged his cable to give to another person (visiting) so he could log on to our network. When that person was done, he plugged the cable back in to his computer, and now it won't connect to the internet and he can't see other computers on the network. I also can't see his computer on the network. His link light on the switch is lit, and the router seems to be able to see him (there's an entry for him in the DHCP table now). I have no idea what is wrong. Help!
