Hi!
In our office I install CRS326-24G-2S+ . Configure it such as router and CAPsMAN for one CAP ac
Upgrade both firmware to 6.43.8
Configure channels for 2.4GHz and 5GHz using. Power up CAP ac. WiFi Analyzer on ANdroid phone view SSIDs from 2.4 and 5 GHz networks by 10 or 20 seconds then all signals go down. Through 10-20 seconds they coming up. 10-20 seconds - going down. etc
Disable provisioning for 5 GHz network - signal making stable from 2.4 GHz network…
What happend? Maybe hardware troubles? everything was very good before moving the office. True, I had to reconfigure the router from scratch, but I used the export settings.
I try to mark checkbox for unusing DFS frequencies but this do not have effect… And why 2.4 GHz band goes down with this action?
One year ago we buy this AP. After unboxing and mounting to the cell, I’m configured CAPsMAN for 2.4GHz only and AP had same simptoms. I was lucky and next day published new firmware for RouterOS. And whole next year I had no problems even two months ago configured the 5GHz band.
And I not remember, ROS upgrading to 6.43.8 before or after shutting down AP in old office…
If you do wireless scanning with some device (i.e. smart phone) while the problem occurs, do you actually see 2.4GHz signal disappear? Or is it just wifi client loosing connectivity for a few seconds (until it connects to 2.4GHz AP)?
I’m connected to other WiFi network and scanning the air. Year ago I had other smartphone. And if client connected to the problem network, I.e. I, the WiFi signal will fall more often.
Ping by cable to AP isn’t fail at this moments…
My brain is crashed…
Yesterday, 06.02.2019, RouterOS getting update to 6.43.11 version. And now the problem is resolved.
I’m only updating ROS and firmware for cAP ac and CRS326.
After testing signal is staying stable at both frequencies
Today we bought new CAP ac. At once click Remove Configuration and upgrade ROS and firmware to last 6.44.1. Power on the CAP and looking at interfaces and provisioning. And the CAP through 10-30 seconds renew wlan interfaces from CAPsMAN… The first CAP upgraded and working correctly. Compare configurations on the first and second CAPs. And I can find a problem : need to manually write value of Admin MAC field. I’m using value = MAC of ether1 interface. 2 hours, flying normal…
If you reset the device to CAP mode, the admin mac is set automatically.
You can verify this by checking the default configuration script:
[admin@MikroTik] > /system default-configuration print
caps-mode-script: #-------------------------------------------------------------------------------
# Note: script will not execute at all (will throw a syntax error) if
# dhcp or wireless-fp packages are not installed
#-------------------------------------------------------------------------------
#| CAP configuration

#| Wireless interfaces are set to be managed by CAPsMAN.
#| All ethernet interfaces and CAPsMAN managed interfaces are bridged.
#| DHCP client is set on bridge interface.

:foreach k in=[/interface ethernet find] do={
# first ethernet is found; add bridge and set mac address of the ethernet port
:if ($macSet = 0) do={
:set tmpMac [/interface ethernet get $k mac-address];
/interface bridge add name=$brName auto-mac=no admin-mac=$tmpMac comment="defconf";
:set macSet 1;
}
# add bridge ports
/interface bridge port add bridge=$brName interface=$k comment="defconf"
}
