i have a great connection aswell, and i do use a personal firewall, but its also verry much WHAT you download, is it know contend verry popular or is it rare contend?

i get around 50 - 150kb/s downloads on almost every known popular file, but on the rare contend it's just dependant on the uploader not the downloader.

also try some suggestions that have been made all over the forum, it's even a sticky in the open forum discussion or the cennections thingy, just search for it can't be to hard.
