Limiting PPPOE bandwith per user

I’ve a small network 50 users give or take and i’m using pppoe because most of my users using wireless access points but my ADSL provider set a limit for me 300gb after that the speed goes down to 128K :frowning: is there any way that makes me set a limit for each pppoe user like hotspot ?

*sorry for my bad English

Use the mikrotik user manager package and setup the radius server.
