I am afraid this is only made clearer if you watched the BE98 Pro from release date. (People complained that ASUS used the highest paying customers as beta testers. All the while ASUS was trying to compete with TP-Link to be first to market to be open minded about why they did it). At first MLO was not there.I still believe IoT Network is something separate. This is what GUI description says as well. People tend to isolate IoT devices from their Main Network and ASUS somewhat automated the process. If ASUS means something else by setting up IoT Network - it's rather strange.![]()
When MLO was released, it enforced WPA3-Personal and AES+GCMP256. For me, it was somewhat a mere inconvenience that I had poor network signal on the ground floor but perfectly fine with the GT-AXE16000 covering the upper floor. BUT with this requirements in mind they asked for a Legacy/IoT SSID on the next page of the setup. (See how they tried there, adding "Legacy").
I have been operating under that mindset for the past year and a half I guess. Then I started seeing complaints/concerned posts about these hidden SSIDs that were (suddenly to me) being made....
I guess the IoT SSID request is now superfluous as the Main SSID can be made compatible with all WiFi generations, and as shown I have deleted the IoT SSID to check....
