Allocating Bandwidth

[jmxthievez]

So recently, my housemates have moved into my house which shares one connection and one router. Last night I was playing poker with a huge fish when my internet connection basically crapped out and I couldn't play. Until I figured out one of my floormates was hogging the bandwidth and I go to his room to find the bastard downloading like 50 torrents. I insta-shut off his computer and go back to play but the fish had already busted [img]/images/graemlins/frown.gif[/img] ugh.

So I am wondering if there is anyway around this to either
a) allocate more bandwidth of this router to myself
b) cap his bandwidth at a certain level.

I say this because most of my housemates only use the internet to check email or whatever and it should be fine and obv its unfair him to hog all the bandwidth downloading movies. So is there a solution or a program that would do this? Or would I really need my own accout/connection?
