    You don't mention what OS version you're running.

    trouble% grep STATUS /usr/include/net80211/ieee80211.h|grep 25
             IEEE80211_STATUS_SHORTSLOT_REQUIRED = 25,

    So the AP and station are not agreeing on how to configure the slot
    time. This may have something to do with the 11g configuration of your
    AP--e.g. did you fix long or short slot time in the AP? OTOH if you're
    running 5.x then there are some bugs in the 11g support that have been
    fixed in current and might cause this.
