Got a strange one here.
I have six Aironet a/b/g access points that wont join my 4402 Wireless
Lan Controller. They are getting IP s from my DHCP server. I have
set up the scope with the Vendor description and Option 43 info
that has the ip of the controller embedded. The controller can ping
the APs no problem but when I reboot them they do not join the controller
Any ideas?
01-31-2014 01:15 PM
What type of AP's do you have, and what code are you running on the WLC?

They are Cisco Aironet 802.11a/b/g Access points. The Cisco Wireless Lan Controller
is running 7.0.235.3. The whole setup is used. It used to work for a different department
in my organization. There network does not connect to mine.
01-31-2014 02:09 PM
ok, but what is the model name of the AP? 1130, 1240 1600 etc.
HTH,
Steve

Paste the output of these commands:
From WLC: sh sysinfo
From AP: sh version
Also connect your AP with console cable and paste the entire bootprocess here.

Just to add.... because it worked before, doesn't mean it will work after changing things around. I would either put the AP's on the same subnet as the WLC management is on.... this is temporary and is fast. Once they join the WLC and download code if necessary, you can then move them to a different vlan. Or you can create a DNS entry and don't worry about the whole option 43 and the hex thing which many have issues with.
cisco-capwap-controller.
cisco-lwapp-controller.
Make sure these entries point to the management ip address of the WLC.
Thanks,
Scott

Can you paste the output of this command from WLC: sh sysinfo
Regards
02-04-2014 07:38 AM
Hi,
its look your AP is not able to establish a secure connection to the controller..
You can do these:
simply set the AP back to factory settings
or
Update WLC software.

How do I reset them back to factory settings? Is that
what the mode button is for?

You can either use the mode button or clear the nvram

Hi,
Unplug the AP then hold in the mode button (use a paper clip or pen tip). While still holding the button down plug the device back in and wait for the light(s) to go steady red. If your AP has a console port you should be good to go
