it should work. It doesn't have a dedicated eth WAN port, but you should be able to set one of the 4 available eth as WAN.Hi GNUton,
I have just ordered a DSL-AC68 and planning on using it as a child AiMesh node at home. The main router is an RT-AC68U running latest stable of Merlin. What I have understood so far is that DSL model has no dedicated WAN port. In the AiMesh System, a child node needs to be connected with its WAN port so that it can take advantage of Ethernet Backhaul. Have you tried this AiMesh function? Pretty happy to test and report back , when I receive the router.
