Disable Radios to Prevent Unexpected Reboot When Upgrading 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
the radios are enabled. However, after the access point reboots the upgrade is complete and the access
point operates normally. To prevent the access point from rebooting unexpectedly, disable the radio
interfaces before upgrading software.

Follow these steps to disable the radio interfaces using the access point’s web-browser interface, which
you can access through the access point's Ethernet port:

Step 1

Browse to the Network Interfaces: Radio Settings page.
