Your BVI is configured incorrectly. You should not have an IP on VLAN 1 and you should use the "bridge-group 1" command on it. As it is the dot11radio0.1 interface is not connected to anything and as such is not coming up.

Also if you wanted to keep your wireless clients on a different subnet then your wired clients. You could always create a second SVI, say vlan 2, and put the wired ports in that other vlan.

Now i did this configuration, but i am unable to get IP address from DHCP on LAN & WLAN, when i manually configure IP address on host's wired lan, it does not work. but when i manually configure IP address on host's wireless lan interface it works perfect. i want my hosts on LAN & WLAN should get ip address from DHCP.
