Well, check Atheros and Ralink for an example. Usually, such chips aren't "built" on purpose, rather, they have 802.11n support disabled due to having been found defective (but usable in 802.11g mode) during manufacturing. > > johannes > -- Vista: [V]iruses, [I]ntruders, [S]pyware, [T]rojans and [A]dware. :-)
