Access Point 1252 Lwapp unable to join Wireless lan controller

[Calin Cristea]

Hello,

I have a wlc 2504, software version 7.0.116 and 10 access points with lwapp.

I have set the proper regulatory domain on the controller.

The problem is that one access point is unable to join the controller. The other 9 (they are all the same model, where shipped together, they share the same country code on back label - E from Europe) joined succesfully on the wlc. They are all in the same subnet.

The output from the ap with problem is :

I have tried downgrade it to autonomus and back to lwapp, the same result.

I have set the proper regulatory domain on the controller. 

What country?

[Calin Cristea]

Romania

[Leo Laohoo]

Can you please post the entire bootup process?

[Calin Cristea]

Unfortunelly i did not copy the entire boot-up and i am not near the ap right now.

What i did notice is that after i type the command

lwapp ap controller ip address X.X.X.X

everything looks fine, i see the correct boot process, on the wlc screen i can see the AP  with the status downloading, after it finish downloading and reboots i have this problem and the ap is missing from the wlc screen

This is the output that i have, what i thought it was relevant:

I have never seen this before.

You sure your WAP is for Romania?

Because a WAP will always join a controller to download the IOS but after a reboot and if the regulatory domain is incorrect, the WAP will NO LONGER JOIN the controller.

[Calin Cristea]

Hello, like i said, the other LWAPP Ap`s successfully joined to the controller.

Question : if i set another EU Country for regulatory domain, is it possible to affect the other allready joined AP's?

Could it be the same bug as the https://supportforums.cisco.com/thread/2084693

regarding the bsnInitRcbSlot: slot 0 has venus radio(UNSUPPORT) problem?

[Leo Laohoo · Accepted solution]

Could be.  Like I said, I've never seen this error message before.

Please contact Cisco TAC and give them the last output you've posted and highlight the error messsage and ask them to RMA the WAP.

[Calin Cristea]

Thanks for the effort...

[Leo Laohoo]

Thanks for the ratings.  Glad to be of some form of assistance.

Thanks Vinay. 

[Calin Cristea]

I have figer it out what it was. It was a hardware problem, if i remove from the AP the B/G 2.4 Module, the AP joined succesfully to the controller.

Sent it back for RMA.
