I have 6 brand new AP1852 ( all in LAP mode )
1 AP changed to Mobility express (WLC ) --> ap-type mobility-express tftp://<ip-tftp-server>/AIR-AP1850-K9-8.2.100.0.tar (newest firmware)
This WLC (and AP ) is ok .. set basic parameters (Web interface very very poor !!!! ) use CLi for SNMP V3, RADIUS , ...
this WLC user ntp server and time zone (Amsterdam, Berlin, Rome, Vienna ) GMT +1:00 ) and summer time.
The AP one this WLC controller is working fine.
Then I tryed to add a new AP (LAP ) same device , software = 8.1.131.0 .
Device will discover WLC (CAPWAP broadcast ) ... but it wil not dowload (or compleet) image ..
only thing that i can notis = the time diverence ... AP = GMT exaple 09:24:23 and WLC = Timezone corected (and local time) 11:24:23 ..
This is a smart log of the discovery of the WLC ... I have DHCP option to set the Time zone (works great for Cisco switches) but these AP and WLC will not use it ... )
Discovery Request sent to 255.255.255.255 with discovery type set to

***** AP stays like this ....******
The 2 devices are connected to the same POE+ Cisco Switch, same untaged Vlan, no firewall or ACL precent ....
I could upgrade this AP to Mobility expres like the 1ste one, but i would preffer the have a ZERO TOUCH AP deployment !!!!
Solved! Go to Solution.

After searching i have found that the image must be in a folder on a tftp server ... it is not downloading it from the controller,
after making the image available the software update wenth smooth..
thanks for the replay ..

That was an error with the version of firmware, i could fix it that way:
The same version in ME and AP
I upgrade the AP with this command:
archive download-sw /reload tftp://<<ip_tftp_server>>/<<image>>.tar
now it works just fine
Cheers

I am a similar issue, I had converted my 1852AP to a CME, and didn't care for the limited interface compared to the 2504 controller, I ended up picking up a controller, the information to demote said to login, which I did get to enable mode which I did and set the NAME#ap-type capwap, so when it rebooted it started to look at the 2504 which is set as a master for an image, which the instructions said if the image is different it will pull an image from the new controller, then I would see it show up in the 2504 under my AP's, and downloading, normally when I first provision they take a while, but this would show.. the a1852i was different than the 2540, while this eventually load?
