First sorry for my terrible english...
I have two nodes of similar characteristics working, one has a RB532 with three radios (one XR2 and two R52) and the other is a RB433 (non AH) also with three radios (three R52H).
The radios have each their sectorial panel of 120º.
The two boards are configured as Bridge no routing or bandwidth control in the APs.
Each of these nodes have conected of about 20 clients distributed in the three panels.
All work fine but I have the serious problem of which per moments, when there is much traffic, they go away pings by clouds, becomes impossible to enter to the CPEs in remote form and begin the corresponding complaints of the clients.
To people that I consult it says to me that a node of those typical must be able to take care of about 100 clients like minimum, but my doubt is in knowing if the Routerboard is being small in processing capacity, which I doubt since at the moments critics the resources at the most mark to 20% of CPU used and half of the memory occupied.
Firstly, I think that the problem was originated by radio interference of other near nodes that there are in the zone, I changed the channels until being annoying to the R52 but always it seems to be solved but the problem returns soon after.
Somebody say me that the R52 is unstable to work in 2,4 but the problem also are present in the clients connected to the XR2 thus also is discarded.
I have been clearing clients little by little, deriving to another equipment, to diminish traffic but the subject is that the problem returns to appear.
I have about 18 or 19 clients in each RB which seems to me a waste, fodder that those routerboards must give for but. I have read many possible solutions and I have applied them to almost all but like I say before, the problem always returns, apparently the only solution is to diminish the traffic to the maximum.
I try changing the ack timeout agreed to the distance of each client, I try too with "hardware retries option" but nothing.
The CPEs are some RB411 and some Ubiquiti Nanostation2.
What can I do to solve this problem, how many clients can receive each RB or radio ?
Thanks in advance for any sugestions or help.
