Disabling Radios to Prevent Unexpected Reboots When Upgrading the System Software
If your access point runs Cisco IOS Release 12.2(11)JA, 12.2(11)JA1, or 12.2(11)JA2, your access point
might unexpectedly reboot after you upgrade to a later Cisco IOS release. Because of a rare timing
condition that affects the radios, the access point sometimes reboots immediately after the upgrade when

point operates normally. To prevent the access point from rebooting unexpectedly, disable the radio
interfaces before upgrading the software.
