I don’t think I am and I am on adsl2+. To be honest my connection at home is garbage dsl without fibre so speeds of 20down and 1up and the isp router from sky is horrible for bufferbloat hence I need it improved. Here is a picture of my d7800 qos page you can see my upload is capped to 0.4mb but it doesn’t actually work and you can see my bufferbloat results. Also here is another user having the same issue with qos upload cap not working
