300 Mbps - 2SS 2.4GHz 802.11n (40MHz chan.) = AN600 class

Overview

Per the Class II permissive change request submitted to the FCC, this model differs from MA073LL/A in that the processor was changed to the 88F5281, the switch was changed to the BCM5397, and the Ethernet CM filter was changed from 824-00339R to 824-M0312R.

Manuf. by Foxconn

The device uses three antennas. The MIMO configuration is assumed to be 3x3.
