I have a mikrotik router and i want to limit the speed of wlan users. I create a queue for target = wlan and set the limit downloa and upload = 64k, but when i test it, this seems not working correctly!
Test download speed > 500k.
The router config is default.
How can i do that

Disable any fasttrack rules on your firewall.

Fasttrack will bypass pretty much the whole stack - including the queues.

It's mentioned very clearly in the documentation.
http://wiki.mikrotik.com/wiki/Manual:Wiki/Fasttrack

Description

IPv4 FastTrack handler is automatically used for marked connections.
Use firewall action "fasttrack-connection" to mark connections for
fasttrack. Currently only TCP and UDP connections can be actually
fasttracked (even though any connection can be marked for fasttrack).
IPv4 FastTrack handler supports NAT (SNAT, DNAT or both).

Note that not all packets in a connection can be fasttracked, so it is
likely to see some packets going through slow path even though
connection is marked for fasttrack. This is the reason why
fasttrack-connection is usually followed be identical action=accept
rule. Fasttracked packets bypass firewall, connection tracking,
simple queues, queue tree with parent=global, ip
traffic-flow(restriction removed in 6.33), ip accounting, ipsec,
hotspot universal client, vrf assignment, so it is up to administrator
to make sure fasttrack does not interfere with other configuration;

You need simple queue with PCQ in order to control all (or specific range) users bandwidth. following are one example:

/ip firewall address-list
add address=10.0.0.20-10.0.0.255 list=USER_LIST

# Marking packets going to USER_LIST
/ip firewall mangle
add action=mark-connection chain=prerouting comment="MARK CONN USER_LIST" src-address-list=USER_LIST new-connection-mark=user_conn passthrough=yes
add action=mark-packet chain=prerouting comment="MARK PKTS USER_LIST" connection-mark=user_conn new-packet-mark=user_pkts passthrough=yes

# Creating PCQ base Queue - 512k per user
/queue type
add kind=pcq name=user-download-512k pcq-classifier=dst-address pcq-dst-address6-mask=64 pcq-rate=512k pcq-src-address6-mask=64
add kind=pcq name=user-upload-512k pcq-classifier=src-address pcq-dst-address6-mask=64 pcq-rate=512k pcq-src-address6-mask=64

#- Make sure you move this simple queue on TOP, or else it will not work
/queue simple
add comment="Allow 512k Down/up per user by zaib" name="512k per user" packet-marks=user_pkts queue=user-upload-512k/user-download-512k target=""
