Downloading Speeds and Linsys Router Firewall

When I first downloaded this program and downloaded my first show, I had a 140-170 kb/s rate and now I can't downlaod a whole show without the transfer failing. The rate has also slowed down to the 20-30 kb/s range. I have a Linksys Router and I have set the portforwading on the firewall to let in BitTorrents. Do I need to configure it another way for the Smart FTp to get back up to speed?

Hi, the speed depends of to much things, if you are downloading a file from a file with small bw and a lot of ppl are doing the same of course you go to be limited, try downloading something of from any big server, for example to see what speed can you reach.
