i purchased ax72 model which has iot network and device isolated option 

i compare models and i see that ax73 has same features and better cpu. 

so i purchased ax73. even though i upgraded firmware there is no iot network and device isolation 

please update that feature for the ax73 

and i understand mesh device like re605x doesnt extend guest network but iot network is part of main router for the smart device

meshing iot network by archer 72 & 73 by using easy mesh extender are must 

please upgrade
