[Sandeep Choudhary]

i think you are running verly old software version on controller.

1852 AP need minimum SW version of 8.1.111.0 or higher to JOIN WLC.

Please paste the information:

sh version from AP

sh sysinfo from WLC

1.- si el AP tiene precargado la versión 8.4.100.0 y al conectar al internet y direccionarlo a una wlc con cualquier otra versión se va a ver en consola lo siguiente:

Se revisa en la flash: a que paquete corresponde la versión 8.4.100.0 y se borra:

Show flash:

delete /force /recursive flash:/c3700-k9w8-mx.153-3.JE

Una vez borrado el paquete se hace reload para que arranque el ap con el banco de IOS de backup:

Generalmente se carga una versión 8.2.100.0 o si no, se carga cualquier versión de IOS borrando toda la flash: (en caso de que el ap arranque en modo rommon)

Hecho ese cambio se conecta al dhcp con salida a Internet y empieza la carga de firmware 8.5.161.0

Terminada la actualización queda actualizado el ap a la versión de la WLC:

Se continúa el proceso de comisionamiento en la WLC y quedan los aps operativos
