1852 AP Unable to join controller

[niketan sutar]

Hi,

I am experiencing a peculiar issue:

i have a 2504 running 8.0.120.0. I am trying to get a new 1850 running ap1g4-k9w8-tar.153-3.JD.tar. ver however whenever i try to get it to join to the controller i get a series of messages listed below.

i have tried upgrading and downgading the AP, tried doing a factory reset but none has worked for me so far.

This AP model is supported by controller version newer than 7.0.0.0!
Discovery response from MWAR ''running version 0.0.0.0 is rejected.
Failed to decode discovery response.
CAPWAP SM handler: Failed to process message type 2 state 2.

If you face issues with converting the AP software to a Cisco Mobility Express software, upgrade the AP
CAPWAP software to the latest AP software version ap1g4-k9w8-tar.153-3.JD.tar. Now, you can convert
the CAPWAP software to the Cisco Mobility Express software AIR-AP2800-K9-ME-8-3-102-0.tar.
This issue occurs in Mobility Express-capable APs shipped with default images or a version of the images
prior to Cisco Wireless Release 8.3. This is due to insufficient space in the AP’s memory or because the
AP has been started in U-boot mode where the image is not found in flash.
The following procedure shows a conversion from the 8.1.122.0 Lightweight APrelease on an 1850 series
AP, and hence uses the corresponding software file. Ensure that you use the appropriate software file
depending on the release you are converting from and the AP model.
• Your AP is either a Cisco 1850 Series or a 1830 Series AP with Lightweight AP software Release
15.3.3-JBB5, for Cisco Wireless Controller Software Release 8.1.122.0, or a newer software.
• A TFTP server and a DHCP server should be configured and accessible.
• Ensure that there are no Cisco WLCs, physical or virtual, in the network while you are performing this
upgrade. The AP must not interface with any other wireless controller while you are performing this
upgrade.
Step 1 Download the AIR-AP1850-K9-8.1.122.0.tar software file from Cisco.com to the TFTP server.
On the Download Software page, for a given release, this .TAR file is labeled, 'Software to be used for conversion from
Lightweight Access Points only'.
Step 2 Connect to the console port of the AP.
Step 3 Log in to the AP using the username Cisco and password Cisco. Both are case-sensitive.
This is the default factory-shipped username and password on all Cisco Aironet APs.
Step 4 To convert the AP from CAPWAP lightweight AP software to Cisco Mobility Express software, use the ap-type
mobility-express tftp://<tftp server ip-address>/<filename of TAR file with path from root on the TFTP server>
command.
The software file is downloaded to the AP, and is written to the AP's flash memory. The AP reboots with a Mobility
Express-capable configuration and starts broadcasting the CiscoAirProvison SSI
