• 400 Mbps - 2SS 2.4GHz 802.11n (40MHz chan., 256-QAM),

• 867 Mbps - 2SS 5GHz 802.11ac (80MHz chan.) = AC1300 class

Overview

• Web GUI: http://dlinkrouter.local

"DIR-853_A1" and "REV1.0" is silkscreened on the board in the FCC photos. A single MediaTek MT7615DN chip serves both 2x2:2 radios.

The identifier on each of the two Qorvo RFFM4552 5 GHz RF FEMs is different which likely just means that they came from a slightly different batch. They are: CF75 and CFBF
