"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).
