I got 4 Asus XT8 a while ago, i had no issues with them. Running AiMesh and AP mode. Today i tried to add the last node and it would not work, at all. I tried just about everything i could find. So i tried to setup the last unit as a new router and it worked, i could update the firmware to the latest 220.127.116.11.386_45934 without any issues, i tried reseting on of the other nodes and added it just fine. I then tried to switch mode to AP and the unit just stopped responding. I couldn't access its web GUI or use the mobile app and the node i just added couldn't find it even when standing next to it. I reset both and set it up as a new router again and it worked, i added the node no problem. Switched to AP and again it died. Since the other 3 units work well with AP i am guessing a HW error? Or do anyone know what is wrong?
