bandwidth limiter 380_7266 , 88u

hi

just doing some testing and cant see to get bandwidth limiter to do anything on the current stock fw

is it broke , if so does it work on merlin fw

have set dhcp reserved ip address and set speeds and selected the client and added it etc

im on a 100/40M plan speed and no matter what i set the bandwidth limit to even 10 down and 10 up i still get my plan speed on the speed test app

i know traditional qos has been broke for a while , is bandwidth limiting the same these days
