Please why ?

Looks like you have all your radios on the same channel frequency. That is, especially when using the 2.4GHz radio, not the recommended config. Besides, you could also have interference with anything transmitting in the 2.4GHz band.

What you can do to improve:

Find the best frequency per ap (doing a scan).
Set the frequency fixed per ap

I would expect three non overlapping channels configured:

/caps-man channel
add band=2ghz-g/n control-channel-width=20mhz frequency=2412 name=channel1
add band=2ghz-g/n control-channel-width=20mhz frequency=2437 name=channel6
add band=2ghz-g/n control-channel-width=20mhz frequency=2462 name=channel11

For reference:
Per radio you can have only one frequency.

Hello.
Thank you .
But i have quescion, how I set diferent freqenci on 3 devices ?
Becouse, I can change freqenci on primary Mikrotik, but I can not change freqenci on sec. devices. Becouse, they are controling primary mikrotik .

Sorry for quescion , i am beginner.
I have on primary microtik diferent freqenci , but on all devices i have only one freqenci why ? How I set diferent frequenci on for diferent device ?

The AP MAIN RADIO lets you set the channel.

The Virtual interfaces follow that channel.

5

Hmm, I canno’t how …

Hello, you need to do your changes on your CAPsMAN, not CAP.

Wrong, when using multiple accesspoints within a network you want to have all settings identical except the channels.

If you want to have network seperation, you can use VLAN:

No, each AP should use a different frequency, because otherwise they will create interferences where their signal overlaps.
Explanation:
https://www.metageek.com/training/resources/why-channels-1-6-11/

https://en.m.wikipedia.org/wiki/List_of_WLAN_channels

In a nutshell, the “useful” part of the transmission is the one “above” noise level, if you have two or more AP’s on the same channel, you are introducing noise at the same frequency and “confusing” devices.

The 1,6,11 is the best possible choice in theory, but it has to be seen in your location if they don’t suffer from interferences by other devices.

10

And setting those channels, is done through provisioning of the radios when using capsman.

11

Yes, it is one method . But I have created two DHCP on two wifi, primary is "work" and second is "Guest" .
But I don't understand how I changed AP settings

12

Documentation helps a lot:
https://help.mikrotik.com/docs/pages/viewpage.action?pageId=1409149#APController(CAPsMAN)-Examples

Please provide a complete config of the device running CAPsMAN.

Thank you ,
It is true, One frequency is bad, I u nderstand . But how set on primary mikrotik ?

14

Thank you.
It is true.
Question is how ? How I changed frequency on 3 AP ? I am in primary settings set one frequency , how I changed frequenci on 3 AP ??

Thank you

Create provisioning rule per radio. Add radio mac to make it radio specific. That’s it.

16

Make 3 provisioning rules.
Each of the rules using a different channel, all the rest stays the same.
Assign one rule (each time a different one) to the mac address of the radio where you want to have that channel being used.

Edit: damn … and now I’m behind erlinden …

17

Thank you…

this rull is ok ?

add channel=channe1 channel.frequency=2412 configuration=work disabled=
no l2mtu=1600 mac-address=DC:2C:6E:F8:B0:88 master-interface=none name=cap1
radio-mac=DC:2C:6E:F8:B0:88

add channel=channe6 channel.frequency=2437 configuration=work disabled=
no l2mtu=1600 mac-address=DC:2C:6E:F8:B0:5D master-interface=none name=cap3
radio-mac=DC:2C:6E:F8:B0:5D

???

If you look at my first reply, you see I added three channels:

/caps-man channel
add band=2ghz-g/n control-channel-width=20mhz frequency=2412 name=channel1
add band=2ghz-g/n control-channel-width=20mhz frequency=2437 name=channel6
add band=2ghz-g/n control-channel-width=20mhz frequency=2462 name=channel11

Create security:

/caps-man security
add name="wpa2psk" authentication-types=wpa2-psk encryption=aes-ccm passphrase=12345678

Then you add three configurations:

/caps-man configuration
add name=app1-ch1-cfg ssid=master security=wpa2psk channel=channel1
add name=app2-ch6-cfg ssid=master security=wpa2psk channel=channel6
add name=app3-ch11-cfg ssid=master security=wpa2psk channel=channel11

And at last, the three provisioning:

/caps-man provisioning
add action=create-dynamic-enabled master-configuration=app1-ch1-cfg radio-mac=DC:2C:6E:F8:B0:88
add action=create-dynamic-enabled master-configuration=app2-ch6-cfg radio-mac=DC:2C:6E:F8:B0:5D
add action=create-dynamic-enabled master-configuration=app3-ch11-cfg radio-mac=DC:2C:6E:F8:B0:21

Does it make sense?

19

Yes, I understand and it is work . Thank you .

But I have problem no. 2 .
Wifi now is stabil but i have UP/dows 8Mbit/. I hed Queue option on 8 Mbit/s .
Now I deleted this queue and I have speed 8 Mbit/s , why ? I deleted queue .

This is me config. It is bad. One radio is OK , and two radios is bad . I do not know .
