Hi,
I was struggling a lot too because my Bufferbloat grades were C or D, no matter what I did. I used this thread as the basic configuration and this another forum to set up some CoDel parameters such as target, interval, quantum, etc.:

But mostly, last reply in this thread remind me an important thing I forgot: bandwidth reservation for QoS to work. If you don't do this, you won't see any difference, believe me!
Reserve at least 5-10% of your bandwidth in pipes, as the user from last reply did, i.e. if you have 100 mbps, set the pipe to 90 mbps. I reserved 20% as my connection speed is pretty variable (blame ADSL).
Now my Bufferbloat tests are A+ with network quiet, even doing the test in a WiFi device:
Unloaded: 71 ms
Download Active: 7 ms
Upload Active: 0 ms
and when all devices are using network actively:
Unloaded: 63 ms
Download Active: 25 ms
Upload Active: 8 ms
