My friend your problem can be resolved by simply removing all the other crap clients from your pc and getting utorrent/mutorrent. It is simply the best. Very easy to use. I have used different clients many times, I have tried port forwarding..sometimes it is a mess...nothn really worked as I wanted so finally I tried utorrent and it works like a magic...try it out for urself..but keep in mind somethn...bittorrent is all about sharing...so don't listen those people who tells u to limit your upload. To get a better speed, u NEED also to learn how TO SHARE...share faily at least 1.0 ratio...
Good luck
