RT-AC3100 - Enterprise Authentication Option Only for Primary Wireless?

[mcse]

I never noticed until recently that Enterprise (RADIUS) option for authentication is only available on the primary SSID and not on the Guest Networks.

Is this true for (all) other ASUS wireless routers?

As most share the base code between them, it is highly probable that it is true of the others too.
