A powerline adapter with integrated switch has 2 or more Ethernet ports you can connect a network device to with a network cable. This way, you can easily connect multiple network devices, such as a laptop, media player, and game console with the powerline adapter. You can create multiple network connections in a room in one fell swoop. For example, provide all network devices in your study with a network connection. Or connect both your gaming computer and your smart television in the attic to the internet via a stable connection. With a powerline adapter, you don't have to pull cables.
