Simply plug the adapters into the socket and they're ready for use. Two of the adapters have an integrated switch in addition to an integrated WiFi hotspot. This way, you can connect two network devices on each adapter at a speed of 100Mbps and use the best WiFi connection anywhere at home.

Note: you have to connect the powerline adapters to the same power phase in the house. If you don't do this, the powerline adapter won't work properly.
