Apparently Broadcom produces multiple versions of the MIMO drivers all depending on how antennas are implemented. The Asus RT-AC66U utilizes 3
external antennas while the Netgear R6300 utilizes 6
internal antennas --- so regardless of the fact that ASUS and Netgear both use the
very same Broadcom BCM4360 Chipset the MIMO drivers are very different. On a pure wireless performance perspective the Netgear R6300 currently is vastly superior [range, bandwidth consistency over time, signal strength on either bands] to the Asus RT-AC66U based on my experiences to date.
