What Dave says, I should have actually looked at the copied link…

Oh, SQM basically is the work of Dave (who wrote the scripts doing the actual AQM&QOS work) and Toke you packaged all this nicely and created the GUI for it (all I ever did was shuffling the GUI around a bit). I just started hacking around the files from sqm-scripts and luck-app-sqm on my cerowrt (so I could immediately do some testing), so I never got around building actual packages (I assume you need to be setup to build whole openwrt/cerowrt images and that is outside the scope of my recreational coding), But that said if you copy the files from ceropackages-3.10/net/sqm-scripts/files to the matching directory on your router you should have a working sqm-script. Or just use a cerowrt built as SQM is standard and potentially hnyman’s build ( https://forum.openwrt.org/viewtopic.php?id=28392 ) that also includes SQM.
