Cisco Wireless AP radio interface shutdown/Operation Status Down

Unanswered Question

Hi,

I am trying to troubleshoot the cause of the wireless AP 1142 radio shutdown; I was wondering where may be a good place to start on it/possibility of the radio shutting down. Once the radio is shown as down; I would just need to re-enable (disable/enable) it and the status changes to up status. I have attached a screen catpure of the radio interface showning down.


The AP radios shutting down is intermittent; some APs has their "A/N" radio interface shutdown while others has their "G/N" radio interface shutdown. Not too sure what may most likely be causing it to shutdown?


Any input is appreciated.


Thanks.

One more thing:

if you are using Power INjector then:


Go to Wireless > Access Points > All AP’s > Click on specific AP then go to  Advanced and check the Power Injector state.

Do you have controller ?? if yes then posts out put of sh sysinfo commad.

Paste the output of sh version command from AP.


Also check: 

1. Choose Wireless > 802.11a/n or 802.11b/g/n > Network

Select the 802.11a (or 802.11b/g) Network Status check box to enable the 802.11a or 802.11b/g band.


2. Wireless > Access Points > All APs then click on specific AP and make sure admin status is enable.

Take a look at the log on the WLC and see if you see anything prior to the radio going down.

Can you provide more info:

If your AP is connected to the WLC, then please provide the following outputs:

1. WLC: sh sysinfo; and
2. AP: sh version

If your AP is connected to a power brick, please attach the picture of the power brick in question.
