@waltered Since your hardware version is V1, you likely won't be able to use EasyMesh with wired backhaul, as it looks like V1 lacks the firmware support for Satellite Mode. However, you can still achieve what you're looking for by configuring the AX1500 in Access Point Mode instead. By connecting ethernet from your main router to the AX1500's WAN port and switching the Operation Mode to Access Point, the router will use that cable for backhaul and simultaneously turn all the LAN ports into an active network switch. If you set the wifi SSID and password to match your main router exactly, your devices will still roam between the two units seamlessly, giving you the functionality you need without relying on the EasyMesh protocol.

  @abermuffin thanks! Are there any other TP Link routers whose firmware supports a sattelite EasyMesh configuration where the LAN ports are enabled?

  @waltered Actually can you grab your AX1500 and look either on the back or bottom of it? Does it give you a specific version such as 1.2, 1.6, etc?
