ASUS ZenWifi AX6000 ethernet connections
1Gig internet line enters the house and connects to Motorola DOCSIS 3.1 cable modem. The modem connects to port-1 of a 10-port TrendNet 2.5G switch. During a recent renovation, I ran 10 Cat6 home runs to various rooms in the house. I’m connecting port-2 of the switch to an ASUS ZenWifi AX6600 XT8. That XT8 is set up as an AIMesh router. I want to run port-3 of the switch to another XT8 in another part of the house to get adequate network coverage. When I connect the second XT8 it setups but uses the wireless connection versus finding the router through ethernet. I then factory rebooted the second XT8 while also changing the system settings for the router and turned on ethernet backhaul mode. After doing this I set up the second XT8 again and it was found but then went into continual sync with the router and never came back. The diagrams for the system seem to show that the equipment has to be hardwired together straight-shot rather than through a switch. Does anyone know if this is a requirement or what settings I might be missing so I can set it up for my config? In addition, my computer connected to one of the ports on the switch does find my printer on a different port. TIA.
