The days of a big dumb Wi-Fi router sitting in the centre of your home are limited. Google Wi-Fi is one of a new breed of wireless router that distributes all those Wi-Fi smarts into different rooms and corners of your home. Instead of one chunky Wi-Fi router sitting near your modem and broadcasting a signal as far around your house as possible, Google's new Wi-Fi pucks connect to one another and rebroadcast a mesh network of strong and stable wireless, giving you a seamless network over a wider space.
