Cisco Access Point Issue_Unable to Ping from LAN

[sijosmail]

One of my  Access Point  Aironet 1600 is unable to ping from LAN, but it is accessible from core switch. And it is showing as  Router (Capability RTI) in Switch CDP neighbors list.

I would check if there is any ACL applied on those vlans ?

Hi Rasika, No ACL. But the other ap's are working with the same ip and port. I am able to ping to gateway and but not to other vlan. And the other ap's are showing as Trans Bride (TI) in cdp neighbors list, but this is showing as Router (RTI)

I have fixed the problem by "no ip routing" command. 

My Cisco access point version is 15.2(2)JB , IP ROUTING is enabled by default and it should not be.

Thanks...
