Cisco 1832i can't join Mobility Express

[Ekobudhi]

Hello..

One of my Cisco 1832i can't joing existing Mobility express installed on other 1832i, meanwhile the other AP can join perfectly.

Here is the log :

Can you post:

1. WLC:  sh sysinfo; 
2. WLC:  sh time; 
3. AP:  sh version; and 
4. AP:  sh ip interface brief

Make sure the 1832i you are trying to join to ME is not running on Mobility Express image.

CJ

AP that running Mobility Express automatically change to capwap and find this controller and join perfectly, only this AP can't join the Mobility Express with that error above

AP running 8.5.140

Thank you for your help

Have you tried adding the WLC info to the AP manually via its SSH:

AP# capwap ap primary-base WLC-Hostname WLC-IP Address

Can you post the complete console output, when the AP boots.

Thanks,

CJ
