Cisco AP not registering with controller

MasterChief — Fri, 08 Sep 2023 21:34:00 GMT

Hello,

I have configured a Cisco 2504 WLC in my home lab. I have a WLAN configured and connect the AP to the switch. The Cisco AP joins the controller, and I can see it, but it does not broadcast the SSID, and the AP blinks Blue, red, and Green.

Cisco AP: AIR-AP3802I-A-K9

Version of WLC: 8.5.182.0

I appreciate anyone help

Is AP working before ? is the AP getting Power from PoE from switch ? what switch model - check the correct power.

Console to AP and post complete boot logs.

The AP was in a production environment so the AP works. Yes the AP is receiving power from the switch. The switch is a catalyst 3750 series-e. As for the boot logs What would be the command to get that?

Factory-reset the AP.

After the AP joins the controller, post the complete output to the command "sh capwap client rcb".

Was the AP factor-reset or not?

I did reset the AP I just changed it to Flexconnect after to see if that would work.

Remote into the AP and post the complete output to the command "sh dot11 wlan".

what is the status after you changed to flexconnect and is this AP joined and able to broadcast SSID ?

Re: Cisco AP not registering with controller

MasterChief — Sat, 09 Sep 2023 09:26:58 GMT

Sorry looks like that command did not take.

After changing the AP to flex connect lt is the same as before. the AP is Joined but not broadcasting SSID. it is blinking Blue, Green, and red.

Re: Cisco AP not registering with controller

IF the LED is blinking, then it means that it is still booting up.

Confirm if the AP has joined the controller using the command "sh ap summary".

Ok, I'm not going to obsess about the blinking LED mystery.

1. Is the SSID enabled?
2. Is the SSID hidden?
3. Is the 802.11a and 802.11b radio enabled

Re: Cisco AP not registering with controller

MasterChief — Sun, 10 Sep 2023 09:03:58 GMT

The SSID is enabled. It is not hidden. The 802.11a and 802.11b Radios are enabled but it says operational status is down. Here is the screenshot

This is the problem.

Where is the screenshot?

Re: Cisco AP not registering with controller

MasterChief — Sun, 10 Sep 2023 11:04:58 GMT

How do I go about resolving it ?

Re: Cisco AP not registering with controller

Leo Laohoo — Sun, 10 Sep 2023 11:09:08 GMT

I need to see the screenshot.

Please share the complete output to the following CLI commands:
