That's what the ax16000 is aimed at (2x10GBe LAN). ASUS needs its product segmentation.As i have no stability issue on the Merlin, i am not going to reset my router. it's will take so mach time to redo everything
Instead, i am going to submit a request ticket to ASUS , see if they can add this feature to GT-AX6000.
Two 2.5G LAN feature should be a quite attractive to potential customer
