I am using Tomato v 1.28. My basic settings and classifications are as per Toastman's recommended settings with a couple of modifications (screenshots attached). I have an issue with the Download rule. Whether it is set at 80% (as recommend by Toastman) or 100% (my preference to maximise bandwidth), and someone wants to play a Youtube video, the video keeps buffering every 20 seconds and the bandwidth available to the download does not decrease. Looking at the graphs, the download and video stream falls within the correct classification. Any idea why QoS may not be working here (i.e. slowing the download to provide more bandwidth for the flash video to play smoothly)?
