AX WIFI on ORBI RBK 752 - 2 pack mesh

[MK2022]

In order to enable AX WIFI connection on the ORBI RBK 752, do I need to set up my WIFI network using WPA3? In such case, are older devices capable of connecting to this network on AC or 2.4 GHz frequencies? 

Thank you.

No.

You can use wpa2. Some older devices don't function/struggle with wpa3. 

AX will still work fine.
