A:Answer Hello, Pickster. A Mesh WiFi or Whole Home WiFi systems consists of a main router that connects directly to your modem, and a series of satellite modules, or nodes, placed around your house for full WiFi coverage. They are all part of a single wireless network and share the same SSID and password, unlike traditional WiFi routers. The Linksys MR9600 is a Dual-Band Mesh WiFi 6 Router that can cover up 3,000 sq. ft, and for you to optimize its mesh system, then you may have to add nodes. For you to check the best unit in your house, you may try using our Velop Configurator: https://www.linksys.com/us/design-your-velop/.
