None of that looks likely to be a problem. First check: $ dig randomstring.org I own randomstring.org, and you are not likely to have it in your cache. Feel free to substitute any other valid domain name that you haven't used in a few days. Does dig respond with an IP address in less than a second? If it takes much longer than 2 seconds, you have a DNS problem. Next, you say you're running a torrent agent. Are you throttling your upload rate to less than 50% of your upstream bandwidth? You should be. By default in most torrent systems, there is no throttling, and it will eat all your upstream bandwidth. Third: can you plug your machine into an ethernet port and change that to be your primary connection? If so, does the problem disappear? That would point to a problem somewhere in the wifi stack. -dsr-
