Amazon has to stand here in the product description: Model Number: DAP-2690 / B But it was Model Number: DAP-2690 / A supplied. Unfortunately, even with the second order. Revision A and B differ in that Revision A no 'band steering' has. Refer to the technical documentation from the manufacturer. The information as to those who require this feature! And as I unpacked the unit, the revision number on the packaging, zuruecksedete again, I give only 3 Stars.
