We have a wifi network with about 100 customers. It has a tree topology with a few powerful point-to-point links at the start which branches out to less powerful links.
In the final branch of the wifi we have about 15-30 customers with varying wifi strengths.
As the usage increases during the evening, the stronger stations take a larger proportion at the expense of the weaker ones. I would like to equalise that. It is not our goal to maximise total throughput, but to allow all users a fair share.
I have put in place queues at the head of the network, but I don't think they are very effective as the primary links ar quite powerfull. I don't think the queues there are very long. I am in the process of installing additional systems just before the final wifi AP.
1. Is there a way to inspect the statistics of the actual queue lengths?
2. Any suggestions on where to most efficiently install the queues in a wifi network with a tree topology?

Thanks!
