I have tried using power line network extenders and Wi-Fi extenders in the past and never had much luck. This package is a wired power line network extender and a Wi-Fi extender. It allows you to extend your existing network in your house or business without running network wires. You plug in the transmitter unit into a wall electrical outlet near your existing router, plug a network cable from the router to the transmitter, and it sends a network signal through your existing home electrical wires to the other unit that you plug into the wall electrical outlet where you need the Wi-Fi or wired network connection. The second unit has a port to plug a computer or network switch (splitter) or router into, and it also sends out a Wi-Fi signal in both 5 gHz and 2.4 gHz. I needed to get a Wi-Fi signal and wired network connection to a 2nd floor room for my in home business. My router is in my basement and because of the way the house is built I had no way of running a wire. The signal from the existing Wi-Fi router in the basement hardly made it to the first floor. I plugged the first unit in the basement wall outlet, not a power strip, made the connection to the router and then plugged the second unit into the wall outlet, not a power strip, in the upstairs room. I waited about a minute and the units connected to each other through the house electrical wires. The lights on the upstairs unit showed I had a good connection and I had both Wi-Fi and wired connections in the upstairs room that I was never able to get a signal in using the old type of extenders. Better yet, I was able to get more than 40 mbps download speed and 20 mbps upload speed, but I do use Comcast, so your speed will depend on your service provider. I then connected a 5 port network switch to the wired port and I was able to connect 4 computers with wired networking and 3 laptops using Wi-Fi as well as an ipad and iphone, and all had great speed. This all worked right out of the box, but for security, you will want to customize the security and Wi-Fi settings. I have to say this will all depend on your existing house electrical set up. If you have several breaker panels due to room additions or very old wiring, you may not be able to use this type of extender. The electrical wall outlets have to be on the same panel, not the same circuit breaker, but the same panel. Other than that it is worth a try. I have now installed 3 of these for other friends and family and had the same results at all locations but one. In one house I could not get them to connect, but found the room was an addition and it was on its own electrical circuit. I plugged it into several other wall outlets near the room and was lucky enough to find one that connected because it was on the main electrical panel. It was close enough to the room that was a dead spot and the signal was strong enough to connect a smart tv and use Netflix in that room. So in the end it did work in all locations. As I said, it is worth a try. I have to add that one of the units I got did not work right out of the box. I had experience with them so I knew right away something was wrong with this unit. I exchanged it for a new one and was up and running in no time.
