My room mate is HOSING down my internet speeds. We have the Cox 6 Mbps, but with their constant downloading of *stuff* and bunches of *stuff* at a time, it's slowing down my connection to where it literally takes 30 seconds to load up msn.com. I don't want to cut off their connection completely, but I want to limit the bandwidth they are allowed to use on my router. Basically I want to do this so they won't suspect a thing. I don't want to have to deal with the "My internet's not working" crap. I have experimented by turning off their connection 1 time and told them I was performing "maintanence" on the router, and you'd better believe not even 2 seconds after that I got the "My internet's not working" knock on my bedroom door. I have DHCP disabled, and we're all set up with static IP's. His ip would be 192.168.1.3. Here is the Router I have http://www.dlink.com/products/?pid=530 any insight would be greatly appreciated.
