I am using meu torrent from downloading torrent file. Recently my downloading speed is terribly slow. It shows a message saying that " Not Connectable. A firewall/router is limiting your network traffic. You need to open up a port." I am using windows xp sp2. I do not know what to do? Please help. It may be mentioned here I am using cable broadband and I am using tp link router tl wr841 n. But with the use of router or without use of router in both cases result is same.
