I understand the queuing and that if I put too high a number, I'll fill queues and end up with bad latency. At the same time, am I correct that if I put numbers that are lower than what I can really get when the line doesn't suck, I'll cap myself to those numbers (here 16.2Mbit instead of 22Mbit or so)? Is it also possible for linux/cerowrt to dynmically detect the queuing/delay in my cable modem and dynamically adjust the QOS values to limit buffering on the comcast side without throttling me down to lower than what the line can do at any given time? I'm also a bit concerned of what happens when comcasts ups my bandwidth without telling me (they do that sometimes) and me never finding out if I have a static QOS value in cerowrt. Can others advise? Thanks, Marc -- "A mouse is a device used to point at the xterm you want to type in" - A.S.R.
