Cindy wants to know what the best mesh router is. Leo says there's a bunch of them, including Plume, Eero, and the Netgear Orbi. They're all very good for people struggling with dead zones in their own home, or if there's a lot of WiFi congestion in the area. Mesh routers work by having a base unit along with extenders positioned all over the house to pass the signal around (much like a "mesh"). The downside is that a mesh router is more expensive, about $300 or more. But for better connectivity, it's worth it. Leo has tried all of them and some are better than others depending on the setup.
