Thanks again... This one has an interesting tidbit: http://www.gamefaqs.com/boards/951942-call-of-duty-modern-warfare-2/52279867 "Steam apparently makes upwards of 40-50 UDP requests when it listens... so it times your router out by over-saturating the connection." That statement vaguely could describe what I see. What I don't know is if the Steam server running in the background is also a server for other players...if it is, then that would also explain traffic use! A snippet on that from http://forums.steampowered.com/forums/showthread.php?t=553390 : "1 player in your server is equivalent to 35 kilobits. So if your speed is 384kb upload, you should be able to handle about 12 players. Also, if you have 512kb upload, then you should be able to handle about 16 players." -----Original Message----- From: tclug-list-bounces at mn-linux.org [mailto:tclug-list-bounces at mn-linux.org] On Behalf Of Mike Miller Sent: Friday, July 23, 2010 6:06 PM To: TCLUG Mailing List Subject: Re: [tclug-list] How detect what's using Internet connection?

Because "everyone" has FF, I'm going to guess that FF causes almost none of the problem. So Call of Duty Modern Warfare 2 sounds like the best suspect. Maybe you can poke around like this and dig something up: http://www.google.com/search?q=%22call+of+duty%22+router I'm curious about what it is doing to cause such severe problems.
