I have a sister who downloads all day long on p2p, as soon as she turns her machine on the bandwidth graph in Tomato shoots up to our maximum download speed. It slows down all other computers, regardless of the built in QOS upstream settings. I've tried everything I can think of to limit her machine from the router but nothing seems to work why isn't there a way to limit her downstream ability? I imagine someone will ask me to just set her p2p program bandwidth lower, I don:thumbdown:'t think she would fall for that and would likely re-up it to full throttle. If the program can throttle download speed, why can't the router? It's funny, her internal ip is 192.168.1.11 so I did an Arp command and found her mac, then blocked her PC from the internet... when I did this the chart showed a dramatic drop in internet bandwidth usage (it looked like no one was even online) then I removed the block and it climbed after about a minute all the way back to the top again. If I can block her completely, I don't see what stops me from the ability to limit her.
