I need to borrow my neighbour's wireless

I need to borrow a nieghbour's wireless and they have a firewall turned on on their computer and they don't know I am on it. Is it possible to disable their firewall somehow? and the wireless is unsecured, I am connected but it is hindering my ability to use a torrent client (Utorrent) to get some things I need to fix my comp. Does anybody have a solution plz?

Do not jew me for information. Go to the library and learn to hack. Nevertheless, your failure amuses me.
