Excerpt: I have a metal building detached from my house. The building has a 60 AMP panel that is fed from the main power going to the house. My shop is about 40 yards from the main. The wireless from the house would not work inside of the shop; after setting up this system I have perfect fast wireless inside...
Panel boxes, not circuit breakers are what matters

Summary: The problem in many of these reviews is that the term "circuit breaker" is being confused with electric panel. Most houses have one or two panel boxes. If both receptacles are served by the same panel it will work.
These devices work well but the information you get about them is really confusing

Summary: First - Linksys or Cisco have three products with very similar names. I think these are the three versions: 1/ Box containing two different devices - one plugs into the wall AC and your router.
Excerpt: After a change of modem/router by Comcast, my WiFi was super poor. I was advised by a Comcast installer about Linksys PLWK400. This item is GREAT. I now have a "hard wire" in my basement and great WiFi in the whole house. Only negative comment is I had to look online for directions to install.
Summary: First I bought the Linksys RE1000 range extender. We had connectivity issues with iPad's, iPhone's, laptops, Blackberry's, etc. Basically anything that moves around the house while on WiFi. The RE1000 works as a proxy so your devices get a fake MAC address when connecting to it.
Summary: I purchased the PLWK400 in 2012, installed the PLE400 adapter in my computer room/office and installed the PLW400 adapter in a tv/game room in the other end of my home and have had no problems with these devices, they perform as advertised.
