honestly you gotta get it in your head? if utorrent is on it goes slow
if not it doesn't so its obviously utorrent causing the problem wrong settings,network card can't handle the connections i don't know but isn't it obvious it utorrent or whatever client your using? try using less global connection put a lower number its not virginmedia for once imo some things wrong your end. or maybe as someone said above maybe your in a trial area i give up lol try a different client try halite (binarynotions.com)
good luck
