	There probably is, I assume you need to install ip-full from the BB repository, and then copy http://snapon.lab.bufferbloat.net/~cero2/cerowrt/wndr/3.10.50-1/packages/luci-app-sqm_3-1_all.ipk and http://snapon.lab.bufferbloat.net/~cero2/cerowrt/wndr/3.10.50-1/packages/sqm-scripts_6-1_all.ipk onto your router and try:
opkg install sqm-scripts_6-1_all.ipk
and:
opkg install luci-app-sqm_3-1_all.ipk

You might need to play with opkg options, but in theory it should work… There probably also is a nicer way like adding a stanza similar to:
src/gz toronto http://snapon.lab.bufferbloat.net/~cero2/cerowrt/wndr/3.10.50-1/packages
to /etc/opkg.conf
but I do not know the exact incantation of that, maybe hnyman, or Dave know the correct answer to this..

Best Regards
	Sebastian

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.
