Thats right M8 you need to assign an IP, ive been port forwarding for games and downloading for over the last 10 years and with many routers.
If you cant find your paper from your Internet Provider ErrorMagnet go CMD in run then type
ipconfig /all this will give you much of the info you need, and you need to have the correct Name Server IP addresses just give your ISP a call they can give you them
Just to add ..
Encrypt your connection (some ISPs cap)
And make a rule in your router Firewall
and you will soon be hitting some good speeds (legal torrents of course)
