@ksauce,

What you're looking for is the Access Point Operation Mode on the Asus Router as this will simply forward the traffic over the network to the Deco's Network. The difference being that you will stay connected to the Access Point longer, as you will not transition between the AP and the Deco Nodes as fluidly compared to using another Deco in your garage with an Ethernet Backhaul.

My recommendation if you would like a complete network solution is to look into our other deco products, since they all work and connect into one mesh network, and choose one that can accommodate the load put on the network through the garage devices.
