Caution: You must buy 2 for this product to work. One will get the ethernet signal into the power lines, and the other will allow you to plug a computer/router/etc. into the other end to get the signal back out.


@joshb0000: Unless you already have some installed. You can just add it to your system. I have 4 in the house (2 sets of 2 different brands) and they work great!
