Overview

"109-700-9100" and "WX5514_V04" is silkscreened on the main board of a production unit.

The board shown in the FCC photos has two Mini PCI slots, but the un-used slot seems to be omitted on (at least some) production models. Likewise, the UART circuitry is omitted, though it is also omitted in the FCC docs.

"WL535AG" and "109-501-5200" seems to be soldered on the wireless module on a production unit.

The U.FL connectors also seem to be omitted on the wireless module, opting for direct soldering to the card.

OEM: Gemtek WX-5514, same Gemtek part as the Linksys WRT51AB.

The default SSID may be default. The FCC manual states it is linksys.

The power adapter shown in the FCC photos is a Linksys MS15-050250-A1D (100-240VAC ~ 50/60Hz, 0.5A -> 5VDC, 2.5A).

This device may use U-NII-2 channels but does not implement DFS since it predates the FCC requirements.
