• 300 Mbps - 2SS 5GHz 802.11n (40MHz chan.),

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

Overview

There appears to be a USB flash drive attached to the main board
in the FCC photos, presumably for the main firmware storage.

• "2976432401" is silkscreened on one wireless module in the FCC photos.
• "2976432501" is silkscreened on the other wireless module.

AR9220 is the (highly) probable chip used for

256MB RAM?

The FCC sample label indicates that the internal model for this device is DRAGON-AP-R.
