Thanks for the guidance Bennor!! I did not even know there were two models in AX86U lineup. Yes my device is indeed the pro version and thus I was able to flash/upgrade to the 3006 firmware.
I used the Administration page of the router and restored it to factory default following the 3006...
All, I wanted to ask this as this thread seem to be the most relevant to what I am trying to do. I am running AX86U device on 3006.102.4 - under this I am able to create a Guest Pro network for IOTs and the VLAN appear in the LAN tab. This is in Wireless router operation mode and not access...
