"Actiontec is a leader in broadband connectivity and broadband-powered solutions. The recent release of the MegaPlug series broadband devices is an innovation that has amazing potential. When used together, the 85Mbps 4 port hub can extend a broadband network to the 85Mbps Ethernet adapter through common household power wiring. Simply plugging the 4 port hub into a power outlet enables the Ethernet adapter to plug into any other power outlet up to 300 meters away and operate as an Ethernet access port. This amazing technology enables a user to connect a computer to the home network using only one cable from the Ethernet adapter to the computer NIC, while the data is traveling through the existing power lines using 56-bit DES encryption."
