Hello,
which IOS version are you running on the Access Points ?
There are a few bugs related to intermittent reboots, here are two of them:

1200 APs' running 12.2(15)JA reboot intermittently. The message that the AP displays before the reboot is %LINK-5-CHANGED: Interface Dot11Radio0, changed state to reset.

CSCea66593 Bug Details
Headline: AP1200 sporadic reboots due to protection violation in tRcv_awc0
Product: ap1200 Model ap1200
Component: ap1200-sw Duplicate of
First Found-in Version: 12.4, 12.2T1
Customer reports a portion of his installed AP1200s reboot sporadically. Sometimes, the reboots happen every 2 or 3 hours, some times they will not reboot
for several days. Customer has upgraded to 12.02T1 without effect. Customer attached a console to a unit, as was able to capture the following output when the unit rebooted:
*** Restarting System in 5 seconds...
protection violation/data access
Exception current instruction address: 0x00030788
Machine Status Register: 0x00001210
Condition Register: 0x42800042
Task: 0xb2c900 "tRcv_awc0"
Customer reports that all AP1200s in his network are hardcoded to 100/half and that they are connected to non-Cisco switches. As well, there are two VLANs
in use.
At this time, there is no workaround available.
Regards,
GP
