SQM bufferbloat

Well, have you read the SQM documentation, here and here already?
If you have not, that would be a good starting point :wink:

That said, could you post the following information:

  1. ISP name, and pln speed (upload and download)

  2. output of the following commands run on a ssh shell on your OpenWrt router:

a) get the name of the wan device/interface: ifstatus wan | grep device
b) get the current configuration of cat /etc/config/sqm
c) disable sqm: /etc/init.d/sqm stop
d) run a dslreports speedtest with SQM disabled and post the results here
e) enable SQM (copy and paste the output here in formatted as </> preformatted text): SQM_DEBUG=1 SQM_VERBOSITY_MAX=8 /etc/init.d/sqm start
f) get the initial cake statistics: tc -s qdisc
g) run another dslreports speedtest and post a link to the detailed results here.
h) get the post-speedtest cake statstics: tc -s qdisc

That should get us in a decent position to continue the discussion/optimization of your SQM configuration.
