Linksys wrt54g wireless router bandwidth limatation (Q?)

Just wondering, is there a way i can lower the speed of the internet for the computers connected wirelessly, so they don't use as much bandwidth as the wired in computer, and with out them knowing?? Note they don't know much about computers so if it's possible it would be pretty easy to pull off.

If this is confusing; let me explain, I am downloading with utorrent right now and someone else who lives here i just can't say no to is downloading; 5 different things at that, I'm trying to download one single thing and it's DRAGGING because of there downloads..

 

Nvm i think i got it.
