Wireless - spectral history to a file

RouterOS General
1

Hello people!!!

I have a site with many APs, recently I disabled WiFi on one of them, we can name it as “AP old”, and added another AP (Also Mikrotik) close to the another. we can call it as “AP new”
So, actually set wireless card in “AP old” to station mode and added “AP new” in the same channel, close to “AP old”
They are facing the following issue, sometimes clients are being disconnected, even with good signal strengh, I thing most values in the settings are ok, The issue is happening with any channel
Currently, I set band to only N, with the security profile only with WPA2 PSK and aes,ccm enabled
I think, maybe there is something generating noise randomly on the 2 GHz band
I left “AP old” in station mode instead of turn it off, to use it to measure the noise somehow.
So, I know about spectral-scan and spectral-history, but is there a way to all the time measure the frequency utilization or noise floor to be readable?
I think with spectral scan I can generate a file unreadable and with spectral history I cannot generate any file

Regards,
Damián

If APold is client to APnew, it will communicate occasionally. If the devices are physically really close, then their Tx power is too high and will mutually overpower each others receiver. Client overpowering APs receiver means lots of interference for whole APs wireless network.

If you want to use AP old for scanning, then connect it to your LAN with wire … and don’t configure it as client of any AP. ROS can perform wireless scanning etc. without being configured as AP or client.

Hello
Maybe I didnt explain it very well. sorry
APold is connected to LAN with wire and it is not connected to any other wireless network, I set it as station mode just to have the wireless card enabled and not delivering WiFi.
My question was related to how to make a readable file with information about the frequencies utilization" in, for examplo, 8 hours of scanning
Any suggestion to know if there is anything causing noise in the 2 GHz band? (Not allways, I think there is something making peaks of noise sometimes)
