Which Xbox console was the first to include a built-in Ethernet port?

The original Xbox was the first Xbox console to include a built-in Ethernet port.

Microsoft designed the original Xbox with an Ethernet port on the console, making wired network connectivity part of the hardware rather than an optional wireless feature. The port supported broadband connections for Xbox Live, Microsoft’s online gaming and digital service, which launched for the console in 2002.

The original Xbox did not include built-in Wi-Fi. Players who wanted wireless networking generally used a separate wireless bridge or similar networking equipment. This distinction matters because later Xbox models increasingly integrated wireless connectivity directly into the console.

Xbox 360 introduced built-in Wi-Fi only on some later revisions; the original 2005 Xbox 360 model required a separate wireless adapter. Xbox One and Xbox Series consoles include Wi-Fi as standard. Therefore, the Ethernet answer refers to a built-in wired network port, not the first Xbox console with integrated wireless internet.
