How to find a dead radio on a 5760 controller

[Craig Hunt]

I have 282 access points on our wireless network which has a Cisco 5760 controller.  All the APs are capable of 802.11a/n/ac and 802.11b/g/n.  Recently I noticed that one access point is only using the b/g/n radio.  I would like to know how I can easily find which AP has the missing a/n/ac radio.

Access Point Summary

	Total	Up	Down
802.11a/n/ac	281	281	0
802.11b/g/n	282	282	0
All APs	282	282	0

Hi Craig,

You should be able to find it easily. Try below CLI command & see

5760#show ap dot11 5ghz summary | in Down

Hi Rasika,

Thank you for your suggestion.  Unfortunately, this does not work for me because the 5GHz radio seems to be completely dead.  Subsequently, I was able to find the AP in question and the 5GHz radio does not even show up as an interface to configure any more.  It's like its not even there.
