Actualy ax hardware I tested on 7.16.2 on MikroTik have only fixed channels,
example 5500 but not 5510, and work ony on 20MHz or consecutive 20+20 or 20+20+20+20 channels.
(hAP ax², hAP ax³, wAP ax, cAP ax, mANTBox ax 15s)

No one support (obviously) 2484
My hAP ax³ do not support 5845,5865 and 5885
South Korea allow also 5945-7125 indoor 24, but I do not know if actually any MikroTik ax products can use that.
