Starlink Ethernet Adapter

If you aren’t already aware, the Starlink router does not have any Ethernet ports. Simply put, it only supports a wireless connection. If you require a hard-wired connection, you’ll definitely need the Starlink Ethernet Adapter.

Installation is as easy as can be. Simply plug-in the dongle to the bottom of the router and connect the dish cable into the port on the opposite side. This will enable a single Ethernet port for plugging in your own device such as a switch, access point or other network accessory. As you can see in the instruction manual, there isn’t a whole lot to it. Just like setting up the dish for the first time, just plug it in and you’re good to go.

Every system can use 10 additional mesh routers, and each can be paired with these adapters to hardwire the Internet to another device for more reliable connection in the mesh wireless system
