Audience linked with Capsman to the hAP ac lite by Ethernet cable disconnecting smartphones on wifi

Please help me. I recently purchased a Mikrotik Audience RBD25G-5HPacQD2HPnD, before that I already used a hAP ac lite in Home AP Dual mode as my Wifi provider for my devices. I installed Audience in HOme Mesh Mode, in the Internet part in Automatic mode, I connected it through an Ethetnet cable for ONU FIBERHOME from my Internet service provider. At Ether2 I connected via Ethernet cable to the second floor in my Residence the hAP ac lite on Ether1. I activated the Camspan mode of the hAP ac lite so that it could take all the settings of the Audience. So far so good, I set up the wifi network with just one Name for 2ghz and 5ghz. On the second floor of my residence where the hAP ac lite is located, Notebooks work normally on Wifi, but Smartphones happen to be a problem: they are disconnecting from the wifi and taking the 4G. At the time of the problem, I keep switching several times between my wifi network and 4G, when it goes through wifi, the following message appears “connected but without Internet”. At this moment he is getting the wifi from the hAP ac lite despite being a bit of the Audience REde Signal, sometimes he starts to pick up the Audience signal depending on where the device is. I realized that the problem is happening in the hAP ac lite because I did the following test: when the problem happens on my smartphone on the second floor, it is alternating between 4G and my Wifi network with the message “connected but without Internet”, I moved around in front of the hAP ac lite, I passed it and went down to the first floor of my residence, where the Audience is, as soon as he got the Audience wifi the problem for, it is normal connected to the Audience Wifo network. Apparently the problem happens in the hAP ac lite. This does not happen all the time, there are times when the smartphone is connected for an hour for example, but suddenly I look at it the same is happening for the problem getting 4G.
Could you help me with this? I inform you that I am not Mikrotik certified, I am just a curious person who has very little knowledge.

Mikrotik Audience RBD25G-5HPacQD2HPnD in Stable 6.46.6
Mikrotik hAP ac lite RB952Ui-5ac2nD-TC in stable 6.46.6

I am from Brazil

Could this be happening because the ONU Fiberhome is in PPPOE + Router + DHCP + Nat Assets providing 192.168.1.2-192.168.1.254 network with 192.168.1.1 gateway and MIkrotik Audience is also in automatic mode with Router + DHCP + Nat active providing 192.168.88.10-192.168.88.254 gateway 192.168.88.1 network

After several configurations that did not work, reading several post here on the forum, I came across this debate: http://forum.mikrotik.com/t/using-mikrotik-hap-as-simple-switch-plus-wireless-ap/107237/1 and I thank the member “vecernik87” that there in 2019 wrote to help another member and ended up helping me too, his problem was similar to mine. I did what he taught, and apparently it didn’t give any more problems. I will now need a couple of days of testing to confirm everything, but it’s been 2 hours and everything is OK.

Thanks to the Mikrotik forum and all the members

" If you start with some config already applied, it is bit more challenging because there will be a lot of setting which needs to be removed/changed. Given the config you posted I would suggest following:
(keep in mind that I still assume you want to have switch+wifi. If your goal is different, let us know)
go to interface → interface list: double-click on entry with ether1 interface and change the List from WAN to LAN
go to IP → dhcp-server: remove or disable the DHCP server (buttons - or x)
go to IP → addresses: doubleclick on the entry with 192.168.0.100 and change interface from ether2 to bridge
go to IP → dhcp-client: doubleclick on the entry and change interface from ether1 to bridge - if your home network is in 192.168.0.xxx range and you want to keep static IP 192.168.0.100, you may disable/remove the dhcp-client instead of changing it.
go to Bridge → ports: one by one, attach remaining ports ether3, ether4, ether5 and wlan2 to bridge (for each, add new entry by clicking on + button, select corresponding ethernet interface and bridge, confirm with OK button)
go to Wireless → Security Profiles: doubleclick on “default” entry, change Mode to dynamic keys, check WPA2 PSK and both aes ccm, uncheck WPA PSK, WPA EAP, WPA2 EAP, and both tkip. Set some wifi password into “WPA2 Pre-Shared Key” fields This step is not necessary but without it, your wifi will be open to everyone and that is dangerous. If you have some really old device which won’t connect, you may try to check “WPA PSK” and both tkip fields. In such case, don’t forget to put your password also to “WPA Pre-Shared Key” field. Old WPA protocol or TKIP encryption are not considered very secure but if your devices require it, I guess you don’t have much choice. You can change it anytime later.
I recommend to do it in order as written, otherwise your mikrotik dhcp-server may interfere with rest of the network.
When you disable your DHCP server, you might lose connection. In such case, don’t panic and connect your winbox via MAC address (works best if you are directly connected by ethernet cable to LAN port - currently ether2)

Once you are done with all these things, you should see your network without any issue on all ports. If you have any issues, share again your current config. As you already noticed, no personal stuff is there and it gives us complete overview of your setting which makes it easy to help.
If everything goes right, you can also clear your firewall rules in IP->firewall->filter and IP->firewall->NAT

@anav
does the wisp ap mode on your cAP configure only 5G wifi or both 2G and 5G? I actually tried that earlier on my hAP ac^2 and it worked perfectly, except skipping the 2G wifi configuration.

Unfortunately the problems have returned, and it is impossible to use the wifi. I disabled the wifi part in Hap Ac lite and everything goes back to normal using only Audience’s Wifi. Unfortunately I made all possible configurations to detect that the problem is in Hap Ac Lite. I left it only with the Ethernet ports enabled, because I need them to take the ethernet cable to other environments, these are working normally. I believe I have a problem with the Hap Ac Lite Wifi interfaces.

thanks
