Ethernet

Windows 11 supports wired Ethernet networks, allowing you to reliably connect to the Internet and access other connected PCs, printers, and other devices.

Ethernet is more common in workplaces than in homes, but if you're lucky enough to have a wired Ethernet connection, you will experience faster speeds and better reliability than is generally possible with Wi-Fi or cellular data connections.
Connect to an Ethernet network
To use an Ethernet network, you will need to physically connect your PC to an Ethernet port on your router or elsewhere in your home using an Ethernet cable. Once you do so, the Network icon in the notification area of the Windows 11 Taskbar will change to indicate that the connection is now available and working properly.

Configure an Ethernet network
By default, Windows 11 configures all Ethernet networks with a public network profile that prevents your PC from being discovered by other devices---and their potentially malicious owners---remotely. Despite its name, a public network is typically the right choice, even if you're using a trusted network at home. But you can configure an Ethernet network as a private network if you wish to share files or connected printers with others on the same network.

To configure the Ethernet network, open the Settings app and navigate to Network & internet > Ethernet. The Ethernet properties page appears.

The following options are of interest.

Network profile type. Here, you can choose between configuring this connection as a public or private network for discoverability and sharing purposes.

Metered connection. Most Ethernet networks are not metered---meaning they do not have a data cap---so this option is usually set to "Off" by default.
