I have comcast basic cable internet, i am getting 7mbps down based on speedtest.net. I am running windows 7, normal installation.

Whenever I am downloading something (via http or ftp or p2p), the downloading stream tends to use up my entire bandwidth, such that i won't even be able to browse the web in a browser. This happens when, e.g. and game update that uses p2p (league of legends, starcraft, path of exile, etc.), or downloading a game from steam, or any regular http download of a large file. When this happens, my mumble will disconnect from the server, gchat will be disconnected, can't load any web pages.

Is this normal? Is there a windows setting that controls bandwidth usage for applications in windows. I remember even in old dialup days I am able to torrent and browse the web (with slower page loading speed but not completely disconnected). Please advise and let me know what's going on.

Doesn't seem normal unless you are using an USB cable to connect to your modem/router. –  Doktoro Reichard Aug 23 '13 at 0:15
    
Have you considered logging into your router and setting up QOS if it has the feature? –  50-3 Aug 23 '13 at 3:52
    
I can setup QoS to limit bandwidth on this computer -- but that's not what i am trying to do. I still want the full bandwidth to this computer, but not having p2p/http download to use all bandwidth that I can't even browse. @DoktoroReichard my setup is pretty normal, ethernet to router to cable modem –  adjfac Aug 24 '13 at 1:45
