While many of the devices we use every day depend on WiFi -- everything from our smartphones to our TVs -- most home WiFi networks are still woefully slow compared to their wired alternatives. Enter Eero, a small San Francisco startup that aims to bring home WiFi into the future. How? By combining the functions of a router, a range extender and a repeater into a single device, thus making the Eero a complete WiFi system for the home. Wirelessly connect two or more Eeros together and you've got an instant mesh network, no IT degree required.
