I am using transmission on my mac and it's really slow. I have had this issue for a long time. When I use speedtest.net, it says I have 30mb/s download and 7.7 mb/s upload. It seems that it is fine. Here's the catch, I only get 2mb/s download on transmission (torrent client) and 400 kb/s upload as well. Here is something I found in my modem/router that seemed to be weird to me. http://tinypic.com/r/nya5af/7 The model number for the modem/router is MI424-WR Rev D Here's my configuration for transmission. http://tinypic.com/r/zyal1j/7 http://tinypic.com/r/x60apd/7 Here is my configuration for my mac network settings. http://tinypic.com/r/wu4j5/7 http://tinypic.com/r/28l850y/7 http://tinypic.com/r/fvjsk4/7 http://tinypic.com/r/wbxrt5/7 Other than that I have no idea whats going on, it's not just transmission, it's everything else.
