Fair enough. If this is the case, then things are correct.

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.
