PCQ is the way to go. You can check on the wiki page some examples on how to implement it to your needs, like:
http://wiki.mikrotik.com/index.php?titl ... edirect=no

Try it out, and then post your config in here if anything does not goes to plan.

It is not about copy paste, is about understanding the example and then implement it on your network.

First, you should start with marking packets coming and going from your wireless interface in the mangle. Then those packet marks are used in the queue tree using the pcq type you have defined. If you establish a pcq rate in the pcq type, that means that customers will get at best the rate specified even if there might be more bandwidth available. If you put the rate at 0 that means that all customers will divide the available bandwidth equally (more or less).

Now, the router does not know what the available bandwidth is, so you need to create a parent queue with the total bandwidth that ISP gives you. Under this parent you create the child queues using the pcq type you have created and the packet marks from mangle mentioned above. You should not attach the queue on the interface in this case.

Post your configs here so that we can have a look at them.

Good, that's the way to start getting help , try it first and post your config.

Now to the point, first it is important that wireless interface named qbtcm is not part of any bridge interface. I will assume it is not.

Second, your mangle seem correct to some extent, but I would mark connections first and then packets, it is less resource hungry this way:

Code: Select all

/ip firewall mangle
add chain=forward in-interface=qbtcm out-interface=WAN action=mark-connection new-connection-mark=upload passthrough=yes
add chain=forward in-interface=WAN out-interface=qbtcm action=mark-connection new-connection-mark=download passthrough=yes
add chain=forward connection-mark=upload action=mark-packet new-packet-mark=upload passthrough=no
add chain=forward connection-mark=download action=mark-packet new-packet-mark=download passthrough=no 

Note that last two rules have passthrough=no, that means that packets are not processed anymore and leave the firewall.

Your queues do not have max-limit specified, that is why you probably see no difference. What are the concepts behind limit-at and max-limit? Limit-at is the value that the queue must satisfy no matter what (CIR), it is the least bandwidth that you always guarantee to the customer. Be careful that the sum of limit-at of all child queues should not exceed the max-limit of the parent queue. Once the limit-at is reached the queue will start shaping and limiting the traffic up to the max-limit value. Max-limit as you might understand is the max value of bandwidth allowed by the queue.
In the parent queue you only need to specify the max-limit, in child queue you might need to specify limit-at and max-limit.

Code: Select all

/queue tree
add name="ispbandwithup" parent=WAN packet-mark="" limit-at=0 queue=default priority=8 max-limit=Value
     burst-limit=0 burst-threshold=0 burst-time=0s
add name="clientup" parent=ispbandwithup packet-mark=upload limit-at=Value queue=wifiup priority=8
     max-limit=Value burst-limit=0 burst-threshold=0 burst-time=0s  

Same for download. Attach the download parent queue to the wireless interface. Remember to fill in the values for limit-at and max-limit.

Last, the queue type. The specification on wifiup is wrong pcq-classifier=dst-address, it should be pcq-classifier=src-address. Also you have specified a rate in there, which I don't think you would want. As mentioned before, specifying the rate means that customer will get 64k even if there might be more available. If there is only one person using the internet he will get 64k even if there might be 10M.
Better have rate=0, this way customer will have the max bandwidth available, depending on the number of active users.

      out-interface=ether1-gateway log=no log-prefix=""

      out-interface=qbtcm log=no log-prefix=""

 6    chain=forward action=mark-packet new-packet-mark=download passthrough=no connection-mark=download log=no log-prefix="" 

 0   name="ispbandwithup" parent=ether1-gateway packet-mark="" limit-at=0 queue=default priority=8 max-limit=0 burst-limit=0 
     burst-threshold=0 burst-time=0s 

 1   name="clientup" parent=ispbandwithup packet-mark=upload limit-at=0 queue=wifiup priority=8 max-limit=64k burst-limit=0 
     burst-threshold=0 burst-time=0s 

 2   name="ispbandwithdown" parent=qbtcm packet-mark="" limit-at=0 queue=default priority=8 max-limit=0 burst-limit=0 
     burst-threshold=0 burst-time=0s 

 3   name="clientdown" parent=ispbandwithdown packet-mark=download limit-at=0 queue=wifidown priority=8 max-limit=64k 
     burst-limit=0 burst-threshold=0 burst-time=0s 

If you see counters running in mangle than that config is working.
As for the queues, don't forget to specify limit-at and max-limit of the queues. If you leave them 0 they will not work.
