My damn flatmate is using all the bandwidth by downloading movies always, never stops, always crappy slow internet for me even though we have 8mb line, I know for a fact that he doesn't share after downloading, he just leeches.
How to stop him ? Can I block the port bit comet uses ? I don't have direct access to the router which is in the adjacent flat, we have a range extender here, i'm unsure which router model it is though I think it's belkin.
Can you help thwart him ?
