UPDATE: From all the questions people are posing, it appears there is a LOT of confusion about what this product does. Very simply, this device converts a coax cable internet connection to (or from) an ethernet cable so it can be plugged into to any device which needs an internet signal such as a computer, xbox, playstation, roku, slingbox, etc.
