RadiusManager-FreeRadius vs Hotspot bandwith shaping

I use Radius Manager with FreeRadius
I put bandwith limitation for some users in radius manager (like 256K) but when I login on my MT-hotspot I run full-rate , over 256K , seems that MT-Hotspot don’t riceve the freeradius limtation.
What can I do? Where is the mistake?
Thanks
