I have encountered such a problem . seems to be a bug
07-18-2013 12:46 AM
Cisco support team says that bug will be fixed in next releases of wlc software 7.4, 7.5 in last quarter of this year .
Only what they offer to use commands:
config 802.11a 11nSupport a-mpdu tx scheduler disable
config 802.11b 11nSupport a-mpdu tx scheduler disable
before this you must disable appropriate networks.
