Hi experts, I am using a RT-ac3100 as my main router with all its 4 ethernet ports used up. Up stairs I have another tplink bridge for one more device requiring a lan connection. I am considering replacing the tplink bridge with Asus RT-AX56U (its on a sale for $129 CAD). I am not able to find if the 56U can act as a AI Mesh node as well as a ethernet bridge. Can one of you who are using AI Mesh help me here?
