Mesh routers, or mesh Wi-Fi systems, use multiple devices (or nodes) across your home to create a larger home network. Essentially, you have multiple routers around your home with these systems, and that will hopefully provide the best coverage possible. Wi-Fi extenders, on the other hand, are usually just one device that extends your existing Wi-Fi signal, and they often require you to switch networks when connecting. Wi-Fi extenders are more affordable, though, and are great if you’re traveling or need a Wi-Fi signal in harder-to-reach areas.
