"There was a time when a wireless router did little more than, well, route. It took bits from the airwaves and put them on a wire, destined for the Internet or perhaps the local network. As the technology matured, product designers started adding things. At first, it was software like firewalls, quality of service controls, and port tunneling and forwarding controls. Then came the advanced things such as VPN and jffs-based file storage – sufficient for a small, static HTML site stored on a cordoned-off part of the router's unused flash ROM. Then came the hardware changes, most relevant to this review being the advent of USB ports. This opened a whole new world of possibilities, generally USB Mass Storage devices and printers. Then Western Digital joined the fray. It added a hard drive to the router. Thus, we have the My Net N900 Central, a 450Mbps x2 high-end wireless router ready act not only as a shuffler of bits, but also as a storer of bits; a router and simple NAS all in one compact device."
