Program to regulate data traffic

As the title says i'm in need of a program that i can use to allocate/divide the bandwith to several PC's. This because when my housem8 streams the router gives him priority (since he's wired) and my internet connection (i'm wireless) starts to lag (even tho our internet is fast enough to support both).

I've tried netpeeker, which works really nice and even gives me remote access to all of my housem8's datatraffic (lol), but it doesn't work on his pc and just makes it blue screen (works nice on mine tho).

So i need something similair, hope anybody knows a reliable one that isn't full of spyware and shit!
