ktorrent clobbers internet connection?

[Matt Price]

hi,

i'm trying to diagnose an intermittent internet connectivity problem and
I believe that ktorrent might be the problem.  I'm connecting via dsl
and through a wireless router.  Ktorrent doesn't report a huge amount of
bandwidth being used -- usually on the order of 30-45k/sec download, and
I've temporarily limited the upload speed to 18k/sec -- but I'm often
faced with enormous slowdowns of the network as a whole, to the point
where no one in the house can connect to the internet.  Is there a tool
i can use to diagnose the internet usage -- say, a tool that identifies
which program is responsible for various incoming and outgoing
packets?  

Thanks for your help,

matt
