HI Anil,

It looks like you are missing the NAT configuration here. Try applying below configuration in addition to your configuration.

interface Cellular0

ip nat outside

!

interface Vlan40

ip nat inside

!

access-list 10 permit 192.168.40.0 0.0.0.255

!

ip nat inside source list 10 interface Cellular0 overload

!

I'm assuming that your Cellular0 interface is up and running for the NAT configuration to work :-)

Hope that helps.

will definately do the provided steps

still i do have one more concern

interface wlan-ap0 published ssid will get the intenet

is there anything need to configure in that interface also

Hi Anil,

I didnt see any wireless configuration here.

If your SSID is mapped to the same vlan (in here vlan 40) you should have internet connection from wireless clients as well.

Hope that helps.
