are you using internet explorer ? sometimes these things don't play well with ff . Try a factory reset .
i was using firefox 3, which was part of the problem. once i went to ie, then i can at least see the settings tab.
several other interesting points.
in my setup, setting the 1522 to bridge mode doesn't work (AT ALL). it has to be set in auto mode.
you cannot access the 1522 wirelessly, it has to be connected into the pc or switch. that REALLY sucks.
you cannot set the 1522 to only run on the n band only, it runs on all bands, that is not optimal for me either.
