Elph if you are downloading with bit torrent and it is making surfing incredably slow then you probably have the upload set to high on your bittorent client.

If you know how much upload your conection has then set your upload to be 90% of max. Ie I have a crappy upload of 500Kb per second so I set my upload limit on my bit torrent client to 400Kb or 40KB. Otherwise you have so much going up your pipe nothing can come down it (ooo err mrs)
