Xbox wireless compatibility depends not only on the generation of Xbox console, but also on the version within certain generations. The original Xbox lacked wireless support, the Xbox 360 initially required a separate device for a wireless connection while later versions had native support, and the Xbox One has native 802.11n wireless connectivity.
Wireless connections for an Xbox can be quite simple or require additional hardware, depending on the particular Xbox in question. The original Xbox did not support wireless connections; instead it had an Ethernet connection that could be used to establish a physical network connection for online play or to transfer data to and from the console. Early Xbox 360 consoles launched with a similar Ethernet port, but lacked native wireless support. A wireless adapter could be used to connect early models to a wireless network, while later Xbox 360 E and Xbox 360 S consoles included Wi-Fi support.
The Xbox One launched with Wi-Fi Direct support without the need for additional hardware or later revisions. An Xbox One console can be connected to a Wi-Fi network quite easily and includes support for 802.11n wireless networking. When connecting to a secure wireless network, a password needs to be provided in order to prevent unauthorized access. Xbox One consoles connected to a wireless network afford access to online play of certain games, with a valid Xbox Live membership, as well as video streaming and other content.
