Powerline adapters expand your network by using your home wiring like an Ethernet cable, sending the Internet signal from your router to any active power outlet. This means you can use your adapter just like an extra Ethernet port, to connect wired devices without rewiring your home.

Rated 5 out of 5 by from What a great solution I have been very happy with the Powerline expansion kit. I live in a large house with very thick brick walls. I tried a WIFI extender which worked fairly well, but had all the down side of WIFI sharing a limited number of channels. I plugged in the two Powerline adapters and suddenly had wiring on my 3rd floor without running a single cable through the walls! Love it.

Rated 5 out of 5 by from Worked as advertised Hooked it up as directed but initially had some extension cords in the system and it did not work. I rearranged so that PLEK400 plugs directly into wall and it works fine.

Rated 5 out of 5 by from Difference Between WIFI and Powerline Internet Service Comcast, PC Direct to E2500 Router 23/25 MBPS down. Wireless to PC in the same room with router 10/12 MBPS down. Wireless to next room through 2 walls 1/2 MBPS down, if I am lucky. With PLEK 400 10/12 MBPS down. It just works! John

Rated 1 out of 5 by from Does not support newer operating systems This worked great when I first purchased them. However, since upgrading my Mac OS to 10.11 (El Capitan) my powerline adapters no longer work. I've been on chats and calls with Linksys and there's still no support for the current OS. It's been over 4 months since Apple's software update and there's still no sign of a new firmware upgrade.

Rated 1 out of 5 by from Stopped working It worked fine but when you want to move to another place the cisco router does not recognize it. If you put in the code an the range extenders forget it know your Wi-Fi goes blank. your logged on but with limited access. It don't pay for the tech support that money can get a new router with a stronger range.

Rated 5 out of 5 by from Solved problem of extending net service Installed in a home built of concrete where a far corner room had 2 bars wi-fi reception from the home's main router on the far end of the home. After 3 minutes of "waking up" the PLEK400s were ready to go. A router was plugged in as access point and I had 5 bars reception. Problem solved. This was an easy fix and saved having to run cable, plus it adds flexibility for future moves.

Rated 4 out of 5 by from Good product I bought this product a good 2+ years ago. Since then, it hasn't caused that many problems, however, a few months ago one of my outlets shorted out when my powerline adapter was in it. I think it damaged some of the components because now my network connection is spotty and not constant. Otherwise it is a pretty good product with only minor complaints.

* Maximum performance for the Powerline AV Network Adapter is derived from HomePlug Powerline Alliance HomePlug AV specification. Performance depends on many factors, conditions and variables, including volume of network traffic, home wiring construction, operating system used, mix of networking products used, interference from other electrical devices, age of home wiring, wireline range and coverage as determined by wiring route or path between devices and other adverse conditions. Power outlets and electrical wiring must all be part of the same electrical system.
