What program did you use? I tried TCP Optimizer from speedguide.net first which was linked by testmy.net. But the result was far from being good. My connection speed was much slower than before.
After that I tried cablenut with settings from vanburen. And it improved my connection speed a little bit. Think I will try the settings for advanced users when I got the time...
But I think I will try being a little more careful in the future...
