• 300 Mbps - 2SS 2.4GHz 802.11n (40MHz chan.) = N300 class

Overview

"WRT-391R Rev. UB" is silkscreened on the board in the FCC photos and a production board.

"T003C22007A" is also silkscreened on the production board.

The production board is using HERMEI and JACKCON capacitors.

The router has three antennas despite the lack of three RX/TX chains.

Two (left and middle on the FCC photos) appear to be used in a switched diversity configuration.

• The AC adapter included with the device (.. at least in the US market) is a

Bestec EA0061WAA (100-240VAC ~ 50/60Hz, 0.5A -> 12VDC, 0.5A).
