I use a wide variety of TP-Link products. They are distinguished by a really very good value for money. The aim was to connect 5 powerline adapters. With 2 pieces is not a problem. Simply press the black button for 3-4 seconds on each part and you are done. If you have more than two adapters, it is more difficult, because there is no real description of the procedure (not on the Internet, even in the operating instructions). Here's a little tip: 0.) on the bottom are MAC address and password. Both please write before starting the installation 1) Connect the first adapter to your router and the power outlet 2.) Connect the second adapter using the included cable to the PC and the outlet 3.) Software CD Launch 4.) Now you can see the adapter on the PC and in the software, if not just press the black button at the two) 5.) Rename the visible adapter (the bottom window), and assign to a network (network name could house or be so), then enter the password (necessary for the security, so no one else can access so simple but can do without) 6. Connect) next Adpater to the PC and start the whole thing all over again, until all adapters are assigned to the same network 7.) Finally replace the two adapters, which was connected to the router, assign to the PC and vice versa, and the last adapter also the network. And then you're done, if you know it had. Just the adapter in the rooms where you need them to connect and it comes. If nothing at all is, call the TP-Link support, if it works. I Wish You Success! PS: The data transfers vary between 70- 130 MB, whatever enough for all cases. The other brand products, it can not get better too!
