As suggested, you are going o have to do something called "Port Forwarding." What this does is it allows the ports that Bittorrent uses (6881-6999) to be open, causing a faster download speed. If you could tell me what type of router you have (Linksys, D-Link, etc.) and the model number of your router, then i can give you a step by step guide to port forwarding. Also, if you have any other software firewalls, you will need to port forward them too. Hope I could help.
