OK, it can¹t be done. You apparently need an Atheron based PC card to run Super-G with or without the Turbo setting. Airport Extreme is not Atheron based and therefore is not compatible with Super-G Turbo settings in some of the most recent wireless routers. However, I found the drivers on the Orange Micro Web site that will allow Mac Users to use the Atheron cards with 802.11a/b/g/ compatibility with Super-G Turbo settings turned on. Reported transfer speeds are supposed to be well over 100Mpbs. Now my question: Has anyone actually tried this combination? (Mac with compatible Atheron based PC card using the Orange Micro drivers and a Super-G compatible wireless router?) jg
