rb433ah + nanostation 5 performance problem

Hi all,
i’ve a rba433ah with 3.23 routerboard os on it,
it’s configured as apbridge with wds default bridge enabled and wmm option configured on nanostation 5.

[admin@Jeko] /interface wireless> print
Flags: X - disabled, R - running
 0  R name="wlan1" mtu=1500 mac-address=00:15:6D:55:85:DB arp=enabled
      interface-type=Atheros AR5213 mode=ap-bridge ssid="TVCC_xxx"
      frequency=5610 band=5ghz-turbo scan-list=default antenna-mode=ant-b
      wds-mode=static wds-default-bridge=bridge1 wds-ignore-ssid=no
      default-authentication=yes default-forwarding=yes default-ap-tx-limit=0
      default-client-tx-limit=0 hide-ssid=no security-profile=default

and this is my registration table

[admin@Jeko] /interface wireless registration-table> print
 # INTERFACE           RADIO-NAME       MAC-ADDRESS       AP  SIGNAL... TX-RATE

 4 wlan1               Scuola_Media     00:15:6D:D8:51:C3 no  -54dBm... 54Mb...
 5 wlan1               Comune  00:15:6D:D8:51:B4 no  -64dBm... 54Mb...

on ubiquity under ccq i’ve on all client 100% value so wireless link seems to be ok.

but…

i’ve tvcc camera over ubiquity, my tvcc ip network camera send a udp stream to a server over microtick eth1

i just make a filter like this

[admin@Jeko] /interface bridge filter> print
Flags: X - disabled, I - invalid, D - dynamic
 0   chain=forward action=drop packet-type=multicast

so it’s not a multicast issue…

this is my prolem:

until i’ve only 3 ip camera streaming all works ok, as soon as i enable the 4 camera streming i start to have packet loss and latency issue on all other streamin.

i create wds static association and i try various combination in order to understand if it’s a “hidden client” problem but in all configuration the only information i can obtain is that as soon i enale more that 3 wds client i start to have problem.

but.. it’s not a bandwith issue, i try to make a speedtest with jperf over each client and on microtick eth1 ↔ ubiquity eth1 i’ve 20 Mb… my udp streaming is only 2 mb…

totally i’ve only 4mb on wlan1…

why i’ve this problem?

p.s
i also try to remove wpa-psk auth without auth the problem persist, i also downgrade ubiquity from last firmware to previous one but nothing..

I am having the same problem as you. And don’t get any answer from Mikrotik Team.

Did you find te way to fix it or something close?


Thank you.

Try reducing the PPS rate on the cameras and use bigger packets

yes i fix removing ubiquity and using microtick cpe…

Thank you, I’ll try that option.
