Mikrotik No Traffic flow to Simple Queue

Mikrotik No Traffic flow to Simple Queue
I setup a simple queue to limit all bandwidth but no traffic show up at Simple Queue. Did i do something wrong ?
Ether1 My WAN (connect from Converter to Ether1)
Ether4 Connect to my AP
Ether5 Connect to my PC

Update : anyone have this problem just delete and open terminal

/queue simple
add max-limit=50M/50M name=private target="192.168.1.0/24" total-queue=default

Change target 192.168.1.0/24 = IP - DHCP Sever - Network - Address

Bump. Please someone walk around here give me some clue.

Fasttrack is disabled?

No bro , i think we have to set Max Limit . This will work.

Did it work?
