An Ethernet switch adapter is a piece of hardware that allows a device or workstation to access an Ethernet connection. Ethernet adapters can be add-ons that go into an expansion board, or they can be directly installed in the motherboard of a computer or device. The most common kind of Ethernet adapter is a PC card, which has an Ethernet connection and a circuit board. Some versions of these adapters can be simply fitted into a corresponding hole in the plastic tower of a desktop computer. Ethernet adapters can use various kinds of Cat5 or Cat6 cables to hook up to an Ethernet connection.

An Ethernet adapter connects a computer to the Internet or to a local network via a wired connection. Most computers include an Ethernet port on the motherboard and do not require a separate adapter, but some laptops only support Wi-Fi connections out of the box. For these situations, or to replace the integrated network adapter on a desktop computer’s motherboard, you can buy and install a separate Ethernet adapter.

As more local networks started to use wireless systems, the Ethernet adapter started to lose ground to network adapter cards that fit into various devices to allow wireless connections. An Ethernet adapter is still instrumental in affecting physical cabled hookups, but many users choose to use a wireless router and wireless adapters for individual devices.

Ethernet adapters require a driver to operate. Often, the operating system will automatically install a compatible driver after you add an adapter. If the system can’t find a driver on its own, you’ll need to download the driver from the adapter manufacturer’s website. After installation, connect the adapter to an open port on your router — or directly to your modem — with an Ethernet cable to connect to a network or the Internet.

Below is a list of some of the very best Ethernet adapters that you can find on Amazon.
