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

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.

Reviews[edit]

from D-Link confirming AC2600 support in the DIR-878 hardware).
