My son uses a powerline adapter to get internet for his PC in his bedroom. He wants to use ethernet for his TV, Sky box and Xbox One.
Can I use one of these https://www.amazon.co.uk/gp/product/B00A121WN6/?tag=ho01f-21 to do this? Is it as simple as running a cable from the powerline adapter to the switch, then ethernet cables from the switch to the devices? If so, will they all work at the same time?
