What is the main difference between Internet in-a-box and a router?
Routers connect computer networks with each other. They allow for an unhindered data exchange between networks. Technically, routers are able to establish a connection from a private network to the internet because it is a (very big) type of network. Every user in the private network is an endpoint of communication with a server in the internet. Apart from this data communication, there usually is no further use of the router possible, e.g. for sending eMails, online access statistics, etc. Internet in-a-box is an intelligent router that combines hardware and software for optimal performance.
