Re: 3600AP crash with error log :Network interrupt loop detected

Konstantin Konotopchik — Thu, 18 Jul 2013 07:46:52 GMT

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.
