Most computer motherboards feature built-in Ethernet adapters, but sometimes for faster speed or because your laptop only links to Wi-Fi without modification, you need a separate adapter.

Ethernet adapters sometimes come to install into a computer internally, in a device slot, replacing the on-board adapter, while others connect through a USB port. All such devices let you link your computer to a network or to the internet. Make the connection work the way you want with an Ethernet adapter.
