I had the same problem with my Netgear device on the pictures made by
the FCC there are nice pins on the board and ASUS just leaves them there
for the production devices, but my Netgear devices did not had them.
The pin layout is probably the same as for the WNR3500L here:

I got ~4MBit/s when running my device in AP mode with old firmware over
~0.5 meters.
