Like Ragu, it's in there. Under wireless settings, select Authentication Method of WPA2/WPA3-Personal on the router. Your devices will also need to support WPA3 for this to work. In our house, we only have 2 devices that support WPA3, both are PCs. In Windows 10, you will need drivers (and an adapter) that support WPA3. I have Intel AX200 based adapters, and if you go to All Settings -> WIFI -> Manage Known Networks then right mouse click on your WIFI connection and select PROPERTIES you can see if WPA3 is being used.Asus just released a firmware for AC86U wich fixes the kr00k vulnerability.

Is this fix already present on Merlin fw?
Also will WPA3 be supported? Or does it need hardware (which i don't think so)?
This is what Windows 10 shows (XXs inserted for some of the info):
SSID: XXXXXXXXX

Security type: WPA3-Personal
Network band: 5 GHz
Network channel: 149

You can see I am connecting to the router using a WIFI 6 (AX) connection and using WPA3.
