And every time I run torrent, my modem would mysteriously reboots several times a day. And It does not happen when I don't torrent. Now I keep on reading that comcast doesn't do such things but the proof is right there.
Seriously? Are you saying that Comcast is "throttling" you by rebooting your modem?
You've got a technical problem going on there. If the modem is spontaneously rebooting under heavy bi-directional traffic (torrents), then the problem is most likely with the modem itself.
