It might use ARP spoofing, I don't recall if the docs ever specified how it does it, but I know the hotspot service will break absolutely everything plugged into that interface unless you add a bypass rule for it.

I don't think that address-pool=none is going to do what you think.

We won’t be able to test until after 5pm tonight but I’ll let you know. I’m just trying to figure out how the devices are getting affected on a different subnet from the hotspot DHCP users.

Did that help any?

I was thinking of this one:
/ip hotspot ip-binding
add address=192.168.1.0/24 type=bypassed disabled=no

replace 192.168.1.0/24 with the network where your unifi stuff lives

I have not tried this with UniFi in particular, but I do know that this will allow that subnet to function without logging or seeing the splash page. I've used it to allow management access to equipment, IP cameras, etc. Without the bypass rule, no device can do anything unless it can open a web browser and log in first.

    This was one option I found.

    /ip hotspot

    set 0 address-pool=none

    You need to add a hostpot bypass rule for the network that you
    don't want subjected to the hotspot.

        Can it be disabled?

        Apparently Miktotik employs something called ARP poisoning as
        a default.  Just letting anyone know that might run into this.

We are on the inside with our laptops on static IP addresses. It kills the laptop from talking to the AP directly. Just
        trying to figure out how that’s happening.

        I believe you will have to manipulate the firewall and walled
        garden

        When we turn on the hotspot, AirControl goes offline and all
        the APs are on a different subnet.  We can’t even log into the
        APs.  Haven’t checked with WireShark yet but just wondering if
        this is simply a setting or some function of the software?
