An advertisement for the device was recently spotted by MondoXbox. The ad, part of a leaflet packed in with the Italian Gears of War 2 Game of the Year edition, pictured the new 802.11n adapter alongside the existing 802.11a/b/g peripheral.

Joystiq today confirmed with Microsoft that the device is real, though the company did not offer any pricing or release date information.

"N" wireless technology represents a technological boost over previous 802.11 wireless standards. 802.11n routers typically extend wireless coverage to twice that of 802.11g routers, and more than quadruple the typical data throughput.
