LWAP migration of AIR-1131AG-A failed bad mzip file

Hello Experts,

I would like to connect a Cisco LWAP 1131AG-A-K9 with a WLC4402 running on 4.1.171.0

Unfortunately, the software downloaded from the WLC is not correctly unpacked on the AP.

I can see an error on the console stating "bad mzip file".

We did several test with converting back to autonomous and migrating to LWAP again using the Cisco Upgrade Tool

but we are failing constantly, even though the Cisco Upgrade Tool states a successful update.

All our european Cisco LWAPs 1131AG-E-K9 are running fine by the way on the controller.

I have added the Console messages to show the error to You.

Who knows anything about that ?

Please support.

Wrong regulatory domain.

You said you have a European LAP1131AG-E but the LAP in trouble is LAP131AG-A.

Re: LWAP migration of AIR-1131AG-A failed bad mzip file

We are using right now only Lightweight-APs with ETSI-Standards on several Controllers without having that problem.

The problem appears during the migration from AUutonomous to Lightweight of an 1131AP with American-Standard.

The according WLC is configured to support US-Country of course.

I cannot believe that this is the problem.  This would mean different LWAPP-images per regulation domain.

Who knows more about this damned mzip-error during the extracting phase of the LWAPP-image ?
