What is a good router for heavy traffic?

I have a dsl-320t which is garbage, freaking italian electronics. My utorrent used to work but now isn't it has something to do with the port forwarding. But the thing is when I go to try and fix it, well 320t is not a selection to go by. So I am figuring it is this modem that is garbage because I can't download anything anymore. No seeders, it won't connect to anyone.
