Deco x55 connecting ethernet causes device to go offline RED
I have my system setup currently with the pods connected wirelessly. I was previously using unmanaged switches at each point where I've placed one of the pods. The main unit is running fine with ethernet to the modem and one switch. The second has a switch working fine. If I try to connect another line for ethernet backhaul it turns solid red and goes offline. The third pod is connected wirelessly. I keep trying to connect a switch that is wired to the main unit to the 3rd pod for wireless backhaul. When I connect it to that unmanaged switch it goes solid RED shortly after plugging ethernet between the switch and that pod. If I disconnect it comes back online. I've tried alternating ports on the pod and switching cables but it still disconnects. I can't figure it out. It used to work fine with my old ax1500 router. Any ideas? Thanks in advance.
