It's not my son running torrent clients, it's me. But I haven't got anything running right now. HOWEVER, when I do download something it won't upload to share. Tells me there's a firewall. I turn off all the firewalls and still can't upload. I have to disconnect the wireless router to allow for that.
Also if he downloads free or free trial software, it's likely there is some spyware that may be slowing you down also. I know he does this, I'll run a spyware program on his, I know he doesn't think that's an issue.
