The Starlink Ethernet Adapter is a simple cable adapter that plugs into the Starlink router. The cable from the dish also plugs into it. Basically, the Ethernet Adapter sits in between your router and dish. What you get by installing the adapter is a single Ethernet LAN port. The port gives devices that are plugged in access to the internet and your home network
You can plug almost anything in to the Ethernet port. Maybe you have a wired security camera. Or perhaps you have a network switch with lots of devices on your home network. Whatever the case, the Starlink Ethernet Adapter is required if you want an Ethernet port with the Gen 2 Standard hardware.
