this is SQM off and it got a C for bufferbloat and a B overall

wow, 560ms of peak bufferbloat on the down, and 240 on the up. vs
~50ms each way.
you should def try correcting for your dsl framing also. you are
leaving some bandwidth on the floor.
Which knob would that be? And note the second URL is the one with SQM OFF

How bad is your dslreports test (send link privately if you like)
For openwrt: you need to install luci-app-sqm on openwrt for a gui and
the related kernel modules. You need to do a bit of testing.
opkg update
opkg install luci-ssl luci-app-sqm # I pull in the full ssl gui as well.
see configuration guide:
https://openwrt.org/docs/guide-user/network/traffic-shaping/sqm
as for autoconf, well, if ISPs shared their actual up/down rates and
encapsulations with their users with a standard message (there is one
appearing for pppoe), it would be a better world. Those ISPs
optimizing their networks dynamically should also be providing a
regular update to their users over a std api, IMHO.
There's been some really cool work recently on getting good graphs of
latency, loss, and marking, out of collectd and sch_cake:
