I am trying to pair 2 rt-ac86u routers. One is connected to my modem and works great. The second I have purchased to put in the garage. For the life of me I cannot figure out how to get the repeater mode to work. I go through the steps and click the operating mode as repeater and it walks through some simple steps of connecting to the original routers ssid and pass. Then it asks if I want to set ip as manual or auto and regardless it still results in the same issue which is that the garage router (repeater) always shows the parent-ap as disconnected. No clue how to fix this!!
