AP not joining

Finn Rud Laursen · ‎04-09-2013

Hi all,

I could need a little help troubleshooting some AP issue.

For some reason some AP will not join the WLC. (WISMII)

I have several hundrede AP online, but still a few offline

This fails:

Well you need to take a look at the AP or console. There have been issues with the 3500's and the white light of death. If you can have someone confirm if the APs led is white or not, that will tell you right away if you need to RMA the ap or not. Other than that, you need to console into the AP and post the output when powering up the AP.

Get someone to console into the AP in question and enter this command: config ap controller IP address

Omg. Problem slowed.

Someone created a new VRF for the AP. They forgot to apply firewall rules. No DNS was allowed causing AP unable to resolve DNS name (Cisco-CAPWAP-Controller) for the WLC mgmt address.

Older AP on the location was able to join because they earliere had joinet the WLC and remembered the IP address.

Thanks all for replying.

Hello,

check if DNS is able to resolve the WLC management address. Thanks
