Set bandwidth limit of multi AP in one lan?

[cbtrocafort]

good day,

hi, we have 1 wan(15mbps) plugged in to pfsense firewall pc, and then 1 switch out for lan. i've set a limit for bandwidth from that lan. let's say 5mbs. so all of the connected devices including pc's and 3 wireless router get that 5mbs.
the problem, i want to set those 3 wifi router to get a limit of 3mbps each. i can't seem to figure it out. i can limit the pc's bandwidth connected to the same switch, can ping too. but the 3 wifi router just get the same bandwidth as the lan. and i can't ping it. but can access the internet.
can somebody please help me. i'm a newbie to this networking thing.
thanks in advance
