Short version $35 for two, that's cheap. The basic setup couldn't be much simpler. Plug a powerline adapter into an outlet and connect it to your router with the included cable. Plug the other cable into an outlet near the device to be connected, connect the supplied cable to the power adapter and the device. In less than a minute he is connected to the Internet. Would you like to add more? Just buy more and connect them. I only use four, with three streaming TVs connected. TVs that used to buffer video streaming over Wi-Fi far too often now NEVER do. BUT - they are sensitive to the state of the wiring in the house and certain electrical appliances. I had very slow speeds - 3-7 MB/s - on initial setup. It turns out that one of the electrical devices that generate "noise" are AC/DC converters, such as B. a cell phone charger. OR power adapter for router and internet modem. When I moved the powerline adapter connected to the router just a meter away, my speed jumped to the full speed of my wired internet (30MB/s). One would expect the microwave to be a problem. But small AC/DC adapters that only use a few watts? Who would have thought? Under no circumstances use the same outlet to power the modem, router, or cell phone chargers that you use to power/connect the first phone line adapter. Otherwise, like I said, it's ridiculously easy. To install. If you live in a house, you can just use them as they are set up. If you live in an apartment, you should probably change the encryption so that when your neighbor buys the device, they don't connect to your network. As part of the troubleshooting, trying to figure out the low speeds initially achieved, I went to the Trendnet website where I found the updated firmware I had installed on each device. This required downloading and running the Trendnet utility for the device. This also required a plugin to be loaded in order for it to work. BUT >>>> If I had just plugged my first powerline adapter into a different outlet, I would never have done any of this. So don't be me. If they seem slow, try plugging the #1 powerline adapter (the one attached to your router) into a different outlet. Or for all adapters, unplug all AC/DC adapters plugged into this outlet. This may require a longer Ethernet cable. I had a bundle so there were no problems. If not, then you will need to buy a longer one. The supplied cable is about four meters long. When powerline adapters first came out in 2001, I tried a few and they were terrible. It's amazing how much better this product has gotten.
