You need to connect your router in the living room with your desktop in the bedroom upstairs. Trailing a long Ethernet cable through the house isn’t a good look, and it’s expensive to install additional wiring in the walls. With powerline, there’s a better way. The TL-PA4022P KIT transforms your home’s existing electrical circuit into a high speed network. No configuration is required – plug your adapter into a power socket and establish a connection within minutes.
