this might just be the slow speeds that occur during peak hours. It will go from the full 3 megabits down to nothing, back up again, which is why I simply got a btguard account to mask my ip address while downloading torrents.. and admittedly I don't seed, I'm just a leecher.
That an a good DNS lookup service since not all of BTGUARD's IP addresses work properly so instead of entering in their generic "proxy.btguard.com" on my torrent I instead select a specific working IP address from this list
