Important Notes

Disable Radio Interfaces When Upgrading from Cisco IOS Release 12.2(11)JA to
12.2(13)JA

If your access point runs Cisco IOS Release 12.2(11)JA or 12.2(11)JA1, the access point might crash
immediately after you upgrade to IOS Release 12.2(13)JA. Because of a rare timing condition that
affects the radios, the access point sometimes crashes immediately after the upgrade when the radios are
enabled. However, when the access point reboots after the crash, the upgrade is complete and the access
point operates normally. To prevent the access point from crashing, disable the radio interfaces before
upgrading to IOS Release 12.2(13)JA.

Follow these steps to disable the radio interfaces using the web-browser interface:

Step 1

Browse to the Network Interfaces: Radio Settings page.
