Wireless Network Adapter
The Wi-Fi (802.11a, 802.11b, and 802.11g) adapter is sold separately for an MSRP of $99.99 or £59.99. There are also many third-party adapters which are connected through the ethernet port, and recognized by the Xbox 360 as a wired connection. Using an official or third-party wireless bridge the console will automatically detect and link up with other Xbox 360 consoles that are within range and form a mesh network. When setting up a connection to an unlisted access point, there is an option titled ‘WPA2′ that is currently greyed out on the ‘Edit Wireless Security Settings’ screen. It is unknown whether or not Microsoft has plans to enable this feature through a future firmware or software update through Xbox Live.It is also possible to connect an Xbox 360 to a Windows XP wireless-enabled laptop or PC via an ethernet cable. If Internet Connection Sharing (ICS) is enabled on the laptop’s or PC’s wireless connection and the laptop’s LAN connection is enabled, the Xbox 360 should be able to share the laptop’s/PC’s internet connection.
