Ethernet-over-powerline range extenders like this one are very much subject to the copper wiring infrastructure inside your home. They really depend upon a "continuous" copper line feed going from the source gizmo to the target gizmo, which is often not the case.
Frequently copper lines go through a circuit breaker box or are somehow otherwise "broken", so that there's not a single line going from the wall socket in the network/router "source" location to the wall socket in the target "client" location. It can also be affected by the types of wall sockets used, and whether there is a grounding pin, etc. So performance for this type of technology is not really 100% guaranteed to provide the claimed spec performance shown on the carton.
But if it works in your situation, it's a great essentially no-cost solution to providing wired/wireless internet access to a remote location where you need it, without having to run ethernet cables. I used this ethernet-over-powerline method in my cousin's home, going from one end of the house in the "office" to the other end of the house in the "family room", just through wall power sockets. It kind of worked pretty well. But in the end after a year of intermittent performance they decided to hire someone to run a true long CAT6 cable connecting the two locations around the outside of the house instead, which of course provided flawless gigabit delivery to the "full 811 wireless access point (WAP)" I installed in the family room which now provided flawless wired/wireless capability to the remote region.
Yet one more technology solution to the problem of somehow delivering wired/wireless ethernet to one or more remote locations when ethernet cable is not directly available is ethernet-over-coax. It makes use of existing old (RG59) or new (RG6) coaxial cable runs throughout the rooms of the house which are used to deliver "old fashioned TV/cable/satellite" service. Ethernet-over-coax gizmos like this NH-310C unit from Netsys
(just like with ethernet-over-powerline you need a pair (or more!), one at the source side and one (or more!) at each destination location) work absolutely 100% super reliably... if you have a coax cable run, even with splitters. Can be used over distances of up to 4000 feet including with coax splitters installed along the way, and provides 2x100Mbps wired ethernet RJ45 channel ports at ether end via the long coax cable in between the pair of gizmos.
I actually use two of these today in my own home, because I never ran an ethernet cable to my family room during construction, and it is today impossible to accomplish. However I did run a coax cable for what in those days was standard to service a "cable box" for TV in that room. Today I use one NH-310CH at the coax outlet in the family room, connected to a source NH-310C located in the network closet area where all my coax runs terminate as well as where an ethernet cable to my main router is available. I have a coax splitter in the famly room from which a second coax cable run then goes over through the ceiling to my kitchen (where again, I never had installed ethernet originally), and where I placed a third NH-310C. Works great, and through two WAPs in both the family room and kitchen I now have wired/wireless 10/100 service throughout all the rooms which are too far away from the main WiFi router to otherwise receive acceptable wireless service that way.
