Please note that the main Deco unit will act as an NAT router by default.Ģ. Here are two typical connection structures for Ethernet Backhaul:ġ. Normally, after wired Deco units with an Ethernet cable, the Ethernet backhaul will take effect automatically. Once Ethernet backhaul is established, the Wi-Fi backhaul will disconnect automatically. And Deco will transmit data between the two units through the Ethernet connection, which is more stable and faster than Wi-Fi. Thanks to this feature, every two Deco units can be wired with an Ethernet cable. Ethernet Backhaul is a feature that makes it possible to wire the Deco units together.
