Summary: The item sounds amazing at first, plugs into your electrical outlet and creates a ethernet channel! Then reality hits and you realize that each additional electrical outlet along the same path lowers your mbps to your router. I could never get the powerline adapters to flash green for the full 500mbps (upstairs computer downstairs router). I would have been okay with decent speeds 40-100 mbps as my ISP will most likely always be the choke point.
Summary: Based on other positive reviews, I have no reason to believe that the Powerline Adapters will not work as advertised. Unfortunately for me, the room my router is in and the room in which I wanted a connection are on two different electrical circuits. This may be a no brainer, but the adapters apparently will not work across circuits.
pointless pass-through and a caveat for sophisticated Mac OS X users
26 March 2012
Summary: 1. The pass-through wall plug is pointless because the additional size required for the unit makes it block the second outlet of a wall plate, so that by taking up two sockets and giving you one back, you might as well save your money and just purchase the basic adapter which only occupies one socket. 2. The power saving mode is problematic. This adapter offers a power saving mode that basically shuts off the device when no activity is sensed over its ethernet port.
