Summary: 1. The mac address & password label have been removed. 2. The bandwidth is extreme low & lossing packets. (about 2~3Mbps bandwidth which means you download speed will be around 200K/S.) I did test my TPlink single powerline, and it can give me full speed (30Mbps) under the same network environment. Suggest: Don't buy it.
Summary: Like some others have experienced, I got 2 PLS400 units instead of one PLE400 and one PLS400. However, both units were bad as I have another set PLS/PLE units to work with. Additionally, the serial number / password stickers were removed.
Summary: i plugged, it didnt work. Called linksys, they said it doesnt work in different breaker circuit. I tried then both in the same room and worked as advertised, fast and no set up process. guess what? today's houses have single breakers per room, i don't think there is still a house that has all or most of the rooms under same breaker circuit. So, the conclusion: product is completelly useless.
Summary: Plain and simple - if the device you're trying to connect is on a different circuit breaker - do NOT buy this product, it won't work. Connect the devices - no network. Instant chatted with support and the person told me plain and simple - this device HAS to be on the same circuit or it won't work. The reason for one star - I had to purchase the product and try it for myself to find that it doesn't work across breakers. Sure would be nice to read about it somewhere..
Not compatible with earlier generation Linksys Powerline AV (PLE200)
Mike G., Amazon
22 March 2012
Summary: I ordered this kit to add to an existing Powerline AV network made up of Linksys PLE200 devices. Apparently, Linksys doesn't keep compatibility between its own devices, even though they're all supposedly compliant with the Powerline AV standard. Before connecting the PLS400 and PLE400 to the network, I upgraded all my PLE200 devices to the latest firmware.
Summary: Esta es mi opinión y seguramente no tiene que ver con otros usuarios. Ami este producto no me ha funcionado desde que lo compré. Múltiples desconexiones y tras varias pruebas opté por devolverlo a Amazón.Probé a configurarlo a través del portatil, conectar un solo dispositivo ya que en mi caso, lo compré para utilizar dos de los cuatro puertos (PS3 y Receptor Digital), cambiar de enchufe, cambiar a cada uno de sus puertos..
Summary: Este producto puede ser bueno con una instalación eléctrica perfecta, pero después de probarlo en 2 pisos tiene tanta pérdida (de una conexión de fibra 100Mbs llega una velocidad de 0,3Mbps) que lo hace prácticamente inútil.
