Ah, fair enough, but could I convince you to run both a wired and a wifi dslreports speedtest (the wifi one from the exact position where you had the less than stellar lede results from), please?
If you do, could you follow the instructions in https://forum.openwrt.org/t/sqm-qos-recommended-settings-for-the-dslreports-speedtest-bufferbloat-testing/2803 how to post a link to the detailed results, please?
And finally it would be awesome if you could also post a link to the detailed result from either the good lede wired speedtest or/and the abysmal lede -wifi speedtest, that way I might get a glimpse of what might be wrong.
The reason why I ask is that this thread will from now on show up for people searching for SQM and bufferbloat, so I would like to have some closure on whether sqm was to blame or not...
And sorry for all the confusing side-conversations going on in your thread...
Best Regards
