I have found a AP during a site-survey of which the a-radio was not up (you could not see the AP and could not connect to it), but in the WLC and WCS there was no error; everythings seemed to be ok (the a-band was UP in the browser) !!!
A reboot of the AP did not solved anything, I have replaced it with a spare one and the coverage in that area is ok again.
One could understand that, if an AP fails without telling you, you can have coverage problems without knowing why !!!
Is there someone who has an idea how we can detect this ? (logfiles, syslog .......)
I have seen the same issue with 1131 APs a few times. The radios were up from WLC and WCS views, but no users can associate. A reboot would fix the issues temporary and issue will come back after a few weeks. Usually this issue can be fixed by replacing the APs and TAC can RMA these APs for us.
It is part of the wireless engineer to verify that the wireless is 100% before he or she hand's it over. You just need to put more time into the testing and verification area so you can make sure you catch it before someone does. Maybe rebooting all the ap's after they join the wlc could be a next step in your procedure, since it might fix 98% of any issues.

This is the start of a display filter cross reference between Wireshark and OmniPeek.
The 1st installment is a table of advanced filters. More filters will be added as time allows.

The script should be completely self explanatory.
