Setting proper SQM to ensure low latency and jitter

Welcome!

I have no answers, but more questions :wink:

Could you please post the following data (mostly the output of commands run on the router via ssh)

  1. cat /etc/config/sqm

  2. tc -s qdisc

  3. SQM_DEBUG=1 SQM_VERBOSITY_MAX=8 /etc/init.d/sqm stop

  4. run a dslreports speedtest according to https://forum.openwrt.org/t/sqm-qos-recommended-settings-for-the-dslreports-speedtest-bufferbloat-testing/2803 and post the link to the results here

  5. SQM_DEBUG=1 SQM_VERBOSITY_MAX=8 /etc/init.d/sqm start

  6. tc -s qdisc

  7. run another dslreports speedtest and post the link to the results here

  8. tc -s qdisc

  9. Copy and paste the content of the "Share Your Result" box from https://www.speedguide.net/analyzer.php

That way we might be able to see what happens and why...

EDIT: fixed superfluous spaces, sorry for the confusion...
