The card pictured in the FCC internal photos is using an AR9160-AC1E (NF2964.02C, 0749, China). The presumed manuf. date code on the card is 0803 (soo.. week 3 [Jan] 2008?).

It would be classified as a variant 1 card according to the criteria below.

.. the one pictured in the external photos (blue PCB, date code 0801) manuf. is obviously an older (pre-final) revision.

noted tested card types

• slightly pink (thin) silkscreened text on front ('CWE ML-1 94V-0), no back silkscreened text (variant 1)
