Unfortunately there is no real solution currently available.

This is an endemic problem in many many network devices, e.g, Jim Gettys (one of the original X11 developers and OLPC developers) has been working on this problem for a while now.  WARNING, the following is highly technical: http://gettys.wordpress.com/2010/12/13/mitigations-and-solutions-of-bufferbloat-in-home-routers-and-operating-systems/ 

The best solution for now is just to know about it: Don't try to use voice applications (like Skype) or realtime applications (like online games, or even much websurfing) while also doing file transfers (like BitTorrent).  

Either alone will work fine, but due to the buffer behavior, the file transfers will disrupt other applications.
