What do you get when you do "sh controller dot0"?

Since the radios are showing reset/down the most likely causes are that either the radio has a station-role of non-root configured and it can't find a root bridge to associate with or that there is not a SSID applied to the radio interface.

It stopped working after a year in the field. How do you establish a failed antenna or radio electrical failure?

Hi,

the most likely cause for this is a problem with the APs power.

Do you use PoE or the PoE-Injector?

Did you change the switch-port, where the AP is connected?

If so, issue the following commands:

- power inline negotiation injector installed

- power inline negotiation prestandard source

The command depends on the switch you are using. The above syntax is the one, if you are using a cisco switch.

Reason: If you are using PoE, the AP needs to know the switchport-MAC-Address. If you are using a cisco switch, the AP automatically learns the Address through the first command.

You can also configure this via the GUI (i think it's under System software or so).

I'm pretty sure, this causes your AP-problem.

Greets,

Sebastian
