Bianca is thinking about getting a mesh router because her Wi-Fi is slow and unreliable. Leo says that a mesh router will definitely do the job, and they're better than a Wi-Fi extender because the extender is only half as fast. But mesh routers aren't cheap. Mesh routers also have a great quality of service with bandwidth shaping, and also parental blocking features. NetGear's Orbi is good, as is the Eero.
