This document describes Radio Reset Codes for the Access Point (AP). The radio reset code can be seen from the AP Command Line with these commands: show controller dot11radio 0 or show controller dot11radio 1.
At the end of the output, you see the radio reset code and this helps you to identify the reason for the radio reset.
Here is an example:
AP#show controllers dot11Radio 0 | i reset Driver TX blocks: in use 0, high 0, at reset 0, fail 0 drop 0 Last radio reset code: 37 Radio resets - total:8 retries:0 failed:0
AP#show controllers dot11Radio 1 | i reset Driver TX blocks: in use 0, high 0, at reset 0, fail 0 drop 0 Last radio reset code: 37 Radio resets - total:8 retries:0 failed:0 radio reset code: xx
