AP operation status down

I just setup a new lan controller and registered some AP's successfully, however the AP's are not broading the SSID's and I noticed that their operational state is down.

Why is it down and I do I bring them back up?

From the controller I can see the AP's are all enabled.

Pls help

AP operation status down

Hi Ronni,

There could be a number of reasons why it is currently in the DOWN state for 'Operational State':

- Is the radio for that AP(802.11a or 802.11bg) Administratively disabled?  If so you will have to manually enable again through Wireless > Access Points > 802.11a or 802.11bg > Hover over small blue box far right > Configure

- Is the network disabled for that specific band?  You can check the network under wireless > 802.11a/n or 802.11b/g/n > Network.  Make sure the checkbox is checked for network status.

If it is not one of these two issues, then we will need more information on the controller model/software in addition to the access points model you are trying to join to give us a better understanding of the hardware involved.

Cheers,
Erwin

Re: AP operation status down

I have this same issue. However I cannot find where you enable the radios or 802.11a & b. I am using the Virtual Wireless Controller version 8.10.122. The APs are 3702E-B-K9. My only issue is their operational status is down and the radios are showing from their respective cli's as administratively down which tells me I need to perform the equivalent of a no shut on them but cannot find that setting in the WLC. I tried following your past instructions -> Wireless -> Radios -> 802.11a/n/ac/ax -> hover over blue box -> configure , problem is I dont see anything in the configuration screen to enable radios.

Re: AP operation status down

Hi @Erik Kaiser 

I think can be a country code mistmatch, which country code are you using in your WLC, USA?

Re: AP operation status down

I set the country code correctly. I actually solved it and it was each WAP needs to be set to flex connect. Now the new issue is trying to apply the license to this latest virtual wireless controller as the guide for my version to install the license is wrong. LOL !
