This will cause problems for power-saving clients, as the ZD1211 chip has no multicast buffering feature, something that must be done in hardware even for softmac cards. (Possibly this can be worked around in the firmware, but so far, no firmware source code has been released for the ZD1211/AR2524, only for the ZD1221/AR9170.) -- Vista: [V]iruses, [I]ntruders, [S]pyware, [T]rojans and [A]dware. :-)
