You will need a dual-band, 1Gb capable router. We recommend the Google WiFi Router.
Sail Internet can setup/provide Google WiFi pucks at $99 each —a good value if you need only one or an extra unit.
While we recommend Google WiFi, you can use virtually any router with an ethernet WAN port. See our Router Selection Guide.
If you have a large home, you can have 2-3 routers that create a Google WiFi mesh.
You can buy a Google WiFi Router 3-pack on Amazon for $259 which is a better deal if you want three pucks. Read our blog post about WiFi router choice.
