I gave LEDE a whirl on WNDR3800 on a 100 Mb DSL line.
Without SQM, speedtest.net gave around 90 Mbit/s of download and 3,6 upload.
I installed sqm-scripts and the luci app and enabled SQM on eth1, set
ingress and egress shaping to 90% of speedtest.net results, enabled
fq_codel and simple.qos

Now when on to dslreports bufferbloat tests and got about 42 Mbit/s. Great
bufferbloat result but ingress seems to perform at just above 50% of
ingress threshold (42 / 90% * 90).

I don't think I've seen that drastic effect when I was on cero and then on
Anything obvious I'm doing wrong?

Also, funny thing, there's a sqm-scripts-extra with cake and also the
packages seem to contain the right kernel modules, but there's not cake
queueing disciple in the luci UI. I found in /var/run/sqm/available_qdiscs
empty files which correspond to the dropdown in luci: codel, fq_codel, pie,
sfq. Could it be that it's just missing an empty file for cake or is that
something more deep?
