Aironet 1850i Access Points

[msmarziali]

Hi, All

We have 4 acces points Aironet 1850i with image mobility express:
AP Running Image: 8.5.131.0
Primary Boot Image: 8.5.131.0
Backup Boot Image: 0.0.0.0
AP Image type: MOBILITY EXPRESS IMAGE
AP Configuration: MOBILITY EXPRESS CAPABLE

We configured the first access point as a Controller,
following the web procedure without problems.

We have not configured the TFTP server: all 4 have the same image.

We are unable to join a subordinate access point (same model and image)
The CAPWAP search starts, in the web console of Controller the new AP is visible with address 0.0.0.0

then disappears and the CAPWAP search restarts.

(we have external dhcp, where we see that the ip has been provided. The dhcp has also provided the ip to the controller. The two ip are pingable)

Any help is welcome.
Thank you in advance

Do you have a console cable? If yes, can you please post the complete output of the joining AP?
Is the master correctly running and offering an SSID?
Is the clock correct on the master?

In the DHCP server, is a gateway IP configured for the pool?
