AP Keeps going down due to interface

Starthorn — Sun, 04 Jul 2021 01:01:48 GMT

I use a 4404 controller and 1131 AP's. I keep getting the error message

802.11a interface of AP ap-nsac-oldcox138-1131 is down: Controller

what does this mean and how can I make it stay up? Is someone attacking it?

The message itself is not related to an attack.

Ideally this alarm indicates that the radios for the AP "ap-nsac-oldcox138-1131" are

down. You could check the status of the radios by going to the web

interface of the WLC and then go to Wireless --> On the left click on

Access Points --> Click on Radios --> Click on 802.11a or 802.11b/g and

click on the radio for this AP to see the current state of this radio.

The AP wont show up on the controller at all. I read that error message in WCS.
