Nv2 Sync Mode Not working

Fri Jan 05, 2018 8:22 am

https://wiki.mikrotik.com/wiki/Manual:N ... on_example
I used this document when processing. I tried "nv2 sync" mode in one location, it did not work. Actually it seems to work, but the clients are not connected. I installed two "SXT G-5HPacD r2" acess points at my office. I did the same thing described in the document. But when you scan, only the master ap appears.

MASTER AP script and monitor
Code: Select all
/interface wireless
set [ find default-name=wlan1 ] band=5ghz-a/n/ac channel-width=20/40/80mhz-eeeC disabled=no frequency=5220 \

    wireless-protocol=nv2

     nv2-sync-period-size: 2
  nv2-sync-downlink-ratio: 50
      notify-external-fdb: no

Because I tested at my office, I assigned the value "TX Power". I tested before I changed the value of "TX Power".

Some of my friends who I thought were professional in this business also experienced the same problems. Nobody has been able to run the Nv2 Sync mode.

Can you help with this? Does Nv2 Sync mode work?
....Thank you now.....

I have the same problem

I used: https://wiki.mikrotik.com/wiki/Manual:N ... ronization and configuration example.

Master access point configuration:
Code: Select all
interface wireless set wlan1 mode=bridge ssid=Sector2 frequency
=2412 nv2-mode=sync-slave nv2-preshared-key=clients2 nv2-sync-secret=Tower1

interface wireless monitor wlan1 
                 status: running-ap
                channel: 2472/20/g
      wireless-protocol: nv2
            noise-floor: -118dBm
     registered-clients: 0
  authenticated-clients: 0
      current-tx-powers: 1Mbps:19(19/22),2Mbps:19(19/22),5.5Mbps:19(19/22),
                         11Mbps:19(19/22),6Mbps:17(17/20),9Mbps:17(17/20),
                         12Mbps:17(17/20),18Mbps:17(17/20),24Mbps:17(17/20),
                         36Mbps:17(17/20),48Mbps:16(16/19),54Mbps:15(15/18)
    notify-external-fdb: no
In the log I see:
wireless,debug wlan1: CC:2D:E0:38:E5:13 attempts to sync
Which corresponds to the example.

Slave access point configuration:
Code: Select all
interface wireless set wlan2 mode=ap-bridge ssid=Sector2 freq
uency=2472 nv2-mode=sync-slave nv2-preshared-key=clients2 nv2-sync-secret=Tower1

interface wireless monitor wlan2
                 status: running-ap
                channel: 2472/20/g
      wireless-protocol: nv2
            noise-floor: -114dBm
     registered-clients: 0
  authenticated-clients: 0
         nv2-sync-state: synced
      current-tx-powers: 1Mbps:19(19/19),2Mbps:19(19/19),5.5Mbps:19(19/19),
                         11Mbps:19(19/19),6Mbps:17(17/17),9Mbps:17(17/17),
                         12Mbps:17(17/17),18Mbps:17(17/17),24Mbps:17(17/17),
                         36Mbps:17(17/17),48Mbps:16(16/16),54Mbps:15(15/15)
    notify-external-fdb: no
In the log I see:
wireless,debug wlan2: attempting to sync to CC:2D:E0:B3:D4:E3
wireless,debug wlan2: synced to CC:2D:E0:B3:D4:E3
I see the difference between the example. In example registered-clients: 1 and authenticated-clients: 1. On the slave access point registered-clients: 0 and authenticated-clients: 0.

Packets between access points do not pass. Master AP IP 192.168.56.2. Slave AP IP 192.168.56.1.
ping 192.168.56.2
SEQ HOST SIZE TTL TIME STATUS
0 192.168.56.2 timeout
1 192.168.56.2 timeout
2 192.168.56.2 timeout
3 192.168.56.2 timeout
4 192.168.56.2 timeout
5 192.168.56.1 84 64 987ms host unreachable
6 192.168.56.2 timeout
sent=7 received=0 packet-loss=100%
Can you help with this? Does Nv2 Sync mode work?
Use Google translate.

Have you made an AAAA sync configuration for sync? Clients shouldn't see two APs in sync, so you have to sync APs that looks 180 degrees away from each other, or ABAB configuration, with A looking 0° and 180°, B looking 90° and 270°

The Nv2 protocol already has a problem in general. but no one makes any statement about these issues. Will we have to try different brands?

Best way is to try different vendor if you need tdma
