Cisco Wi-Fi access points face critical storage crisis affecting enterprise networks globally. Over 230 models running affected IOS XE versions generate 5MB of undeletable log files daily, progressively consuming flash memory until devices lack space for essential software updates. This creates a dangerous catch-22 where administrators cannot download patches to fix the problem because storage is exhausted. The faulty cnssdaemon.log file cannot be deleted through standard command line interfaces, forcing organizations into potential bootloop situations. Cisco's recommended solution requires upgrading to patched OS versions, but devices with full storage may lack capacity for the update itself.
