HELP: High latency, bur off/on interface resolve

RouterOS Wireless Networking
1

Hi all,

I crazy about this problem… clients wants to kill me… The problem is the following:

Tower with 4 sector 90º 17db, 2 rb133 with one CM9 each, and a PC (Pentium IV 3.0GHz, 256Mb) with 2 DLink AG530 PCI Cards.
The number of clients in each one varies, 40, 30, 20 and 15, but the problem occurs in all of them. The latency goes crazy to high and navigation get horrible. I tried blocking P2P, limit TCP connections, change channel, activate DFS, but no result. Only thing that resolve, momentaly, is to disable/enable the wireless interface, the latency goes down e every thing works fine for about 1 hour or 2, and happens again… All my clients uses RTL8186 based AP.
I don´t know what to do anymore…

PS: In another city, I have other tower with the same config and works fine.

First, make sure you aren’t using NStreme. Second, watch the interfaces in WinBox and look at the PPS. If you see high PPS on all of the WDS interfaces, then you have a broadcast or multicast problem with a customer.

NStreme disabled and WDS disabled.

Antena 4(RB133/CM9) high latency this moment → PPS TX = 100 / RX = 91
Antena 1(RB133/CM9) working fine at this moment → PPS TX = 150 / RX = 150

I use the same SSID for the four antenas, with diferent channels and diferent IP subnet in router mode (don´t use bridge).
