Wi-Fi signal does not appear

Hello
I am new to the mikrotik environment, yesterday I received 2 cAP ac that I bought to replace some ubiquiti uap that broke.
The question is that I want to use these cAPs as simple APs but I have problems with the wifi. I have configured a bridge with all the interfaces and I have configured the Wireless (tango in 2.4ghz as in 5gh) the problem comes in that none of the 2 cAPs is generating a 5ghz signal and only one of them generates a signal in 2.4GHz in a stable way .
I don’t really understand what is happening and why they are not generating a signal.

The topology of my network is as follows:

And the Wireless configuration on both devices:
2.4ghz configuration

5ghz configuration:

And this is the total configuration of one of the cAP ac:

Anyone have any idea what might be going on?

The 2.4G band is subject to interference, especially if you use 40MHz bandwidth. Only use 20MHz bandwidth and channel 1, 6 or 11 (as being the only non overlapping channels with this width).
Set country and Frequency mode to regularity-domain. And don’t use 802.11B…unless you have a really ancient device that only support B.

For 5G band: Set country and Frequency mode to regularity-domain. For 80MHz channel width only use channels: 5180 (36), 5260 (52), 5500 (100), 5580 (116), 5660 (132) or 5745 (149) depending on country code. If you choose a DFS channel it might take up to 10 minutes before the SSID is visible.

Hello, thanks for responding, I have configured the wifi as you have told me, the signal continues to do strange things, sometimes it appears in the wifi analyzer and sometimes it does not. In the ubiquiti AP the signal is shown and is stable so I rule out customer problems.


I don't know if it has something to do with it, but the 2G LED flashes quickly and the 5g LED blinks more slowly.
