We just moved into an older 2 story home and I was challenged on how to connect our multiple internet devices (BlueRay with Netflix, Computers, Etc). Doing some research I discovered these internet adapters and I cannot believe how easy it was to wire this old house. Simply connect one to your router and the other in an electrical outlet in the room where you need connectivity. that simple! This worked so well I bought another set and now have full connectivity in my entire home. Very handy because in this older home where we have an office upstairs and downstairs needing connectivity
