the vast majority of times i try to download a file via bittorrent my internet becomes unresponsive within minutes, but it takes longer to actually admit the internet doesn't work. I've never tried leaving it alone to see if it will start working again(for more than 15 mins or so) because i usually just restart the router to get it working again. if i dont try to continue the torrent download at this point my internet will be fine and i pretty much never have other similar problems. I've watched the network usage in task manager while trying to download a torrent but it only hovers around 18% or so. some information on this problem or how to remedy it would be nice.

forgot to mention this but yes bittorrent is excepted through my firewall.
