The access point is an A-only unit made by Netgear. It advertises turbo modes only upto 72 megabit in it's documentation. Concerning your 'rarely used' comment, is it that access points based on Athros are rare or that turbo mode itself is not that useful? Maybe it would be sufficient to have a mode 11a-turbo in addition to mode 11a that is not part of the automatic scan.
