Hey Solid thanks a lot for your reply, I don't exactly have control over his laptop, I did once limit his downloads to 64kbps(mine is a 1mbps connection) but BitComet still kept sucking all the bandwidth, I also kicked his MAC a few times, but that wasn't exactly a solution lol, I did also try to mess with his web pages using Squid Proxy but that was Linux *SIGH* so I didn't get very far
So as I suspected QoS is needed, I upgraded from my OLD DI-524 to this Belkin, and surprisingly it still doesn't have QoS

looks like that's the only solution now, so I shall close this thread soon, thanks again
