The Devolo dLan 500 Duo is a powerline adapter that's suitable as an expansion for a network consisting of multiple other Devolo dLan adapters. With this powerline adapter, you can expand the computer network via your home's mains electricity. As such, a network of powerline adapters is commonly known as 'socket internet'. The remarkable thing about the Devolo dLan 500 Duo is that the adapter has 2 network connectors instead of 1. This allows you to include your smart TV and your gaming console in the home network, sharing internet with both device. That's 2 fewer network cables you'll need in your home.
