Richard wants to know how different a mesh network is from a network extender. Leo says that extenders repeat the signal and send it along the way. So the bandwidth gets cut in half because it's communicating half the time. Mesh, by contrast, has its own back channel to talk to the router and satellite units. Leo says it's a little primitive, but he could have two of the same wifi routers with the same SSID and password, and they could hand off the signal to each other. But the Netgear Orbi Mesh router is the better option. And it uses WiFi6.
