• 1300 Mbps - 3SS 5GHz 802.11ac (80MHz chan.),

• 600 Mbps - 3SS 2.4GHz 802.11n (40MHz chan., 256-QAM) = AC1900 class

Overview

"AP-MTKH7-0002 REV1.0" is silkscreened on the board in the FCC photos.

• Web GUI: http://dlinkrouter.local

Despite being labeled as an AC1900 router, this device appears to be identical to the AC2600 D-Link DIR-882 rev A1 aside from the USB ports. D-Link claims only 1300/600Mbps speeds but also claims that it supports four streams. The hardware is capable of four streams. FCC test reports show four-stream speeds so that's what we'll go with for specs.
