If the torrents are going at a decent speed, then it's likely nothing to do with the connection.

I'm confused a bit by that, because it works on another computer, but I'm fairly sure Flash was downloading slow as hell for me too (I was installing it on my linux box, the licence agreement in firefox took too long to download so I gave up, it was loading in ~50 character chunks).

Try and find flash player on bittorrent
