Enabling QoS lowers "quality" grade (but helps bufferbloat)

    Running an RT-N66U using the 374.43 forked firmware. When I run the speed test on dslreports, I get an A+ for Quality but an F for BufferBloat. Speeds for down/up are generally around 69/6.

    So I enable QoS with down/up of 63/5. Re-run speed test and my BufferBloat increases to a C, at least. But Quality goes from A+ to C. The speed test help suggests this is due to having to packet loss. Why would it decrease? How can I fix this?

    QoS disables hardware (NAT, CTF) acceleration

    I think that depends on router model.. on my ac3100 qos only disables FA but leaves ctf enabled
