If you were like me and frustrated by the ultra slow d/l's using bittorrent (like 1-5kb/sec) I recently found this handy tip. If you're using a router you must open up the ports between 6881~6999.
Now to do this you need to open up your routers menu by typing in the ip address of it in your internet explorer window. Then you need to find a section called 'Virtual Server.' (Im aware that everyones router will be different so find something that is along the lines of Virtual Server).
Now for me to open the ports I simply typed 'bittorent' in the box under application. I left the protocol type as 'tcp' and under port I entered '6881' in the first box I had displayed and '6999' in the second box. I then entered the ip address of my COMPUTER, NOT my router (it's important that you put your computers ip in). Finally I saved the settings and closed off the window.
I really hope this helps everyone, I am now d/ling the episodes at 40-55 kb/sec and couldnt be happier.
