Re: RB911G/RB912G - poor ccq/performance in benchmark setup

@uldis - if you want i can arrange a lab setup and give you remote acces via teamviewer to see how it's working.

Re: RB911G/RB912G - poor ccq/performance in benchmark setup

I have observed this behavior in lots of setups (lab, indoor, outdoor), different combinations (802.11n, nv2, nstreme), on all units with new Atheros chipset (912, 911, SXT Lite 5).

I haven't found a solutions.

Re: PTP Link between RB433AH R52HN and Sextant

try to use nv2 protocol instead of nstreme and see if you still have disconnects.

Re: RB911G/RB912G - poor ccq/performance in benchmark setup

I have used RB912G as AP and RB911G as CPE and not even like this the CCQ is not 100% as it should be. The variation is quite big (from 64% to 98%). If in the same setup i'm using AR9220 for both AP and CPE (any of the following: R52Hn, R52n-M, RB711G-5HnD, RB711GA-5HnD, SR71-15, etc) the performanc...

Re: RB911G/RB912G - poor ccq/performance in benchmark setup

I have traffic on link, while reading CCQ.
Also max MCS is limited according with CCQ, meaning 78/104mbps in 20MHz.
Maybe there is a problem with QAM64 MCS's.
I have latest firmware 6.1.

RB911G/RB912G - poor ccq/performance in benchmark setup

I am using RB911G-5HPnD or RB912UAG-5HPnD boards as CPE in a PtP link in benchmark setup ("on the table" with RF cables and attenuators ~80dB on each RF chain). For AP i have RB411GL+R52Hn. UL and DL RSSI is about -60dBm on each chain. In this scenario I'm unable to achieve 100% CCQ value on DL (RB9...

Write to disk log files or graphs

I want to enable logging to disk (all topics: info, warning, error, critical) and store graphs (interface and resources) on all Mikrotik devices in my network. How is this affecting performance (since i know that writing to flash is slow)? May i end up with damaged units in case of power outages whi...

Re: Alternate SSH Port on WAN?

Default ports for all services (ssh, web, telnet, ftp, etc) can be changed from IP -> Services.

Re: RouterOS v6rc11

I have installed a PtP link in lab, with 2 RB711G-5HnD in bridge mode, sw version 6.0rc9. The link was in idle for about 6 days.
On both of them it looks that there could be a problem with memory leak - as you can see from the graphs.
I have upgraded to 6.0rc11, but i think the problem is still there.

Re: RouterOS v6rc11

I have configured interface and resources graphs, both to be stored on disk.
After reset only resources graphs remain, interface graphs are lost and started again, like in the case when they are stored on ram.
i have checked both 6.0rc9 and 6.0rc11.
It was ok in 5.23.

How to limit unknown unicast traffic (in pps or mbps)

Hi, Is there a way to limit unknown unicast on an AP-Bridge WDS-dymanic mode? My problem is that i have several SXT's connected to AP, each SXT with multiple MAC's behind. If one SXT goes out of link (for different reasons, like power outage, power cut, etc) all downlink traffic with DST-MAC one of ...
