Question : How do I specify a dhcp range on a Cisco Aironet 1240ag access point?

I have a cisco 1240ag access point which i have set up as a dhcp server for wireless clients. How do specify the dhcp range. It is giving out conflicting ip addresses from other APs.

OK, how abot this...
This network and subnet mask will deliver the addresses 193 to 249, with 250 to 254 excluded for router gateway, and anything else that might need a static.  Exclude less if nothing else is needed.

! to config the DHCP pool
ip dhcp excluded-address 192.168.1.250 192.168.1.254
ip dhcp pool YourOffice_Pool
   network 192.168.1.192 255.255.255.192
   domain-name YourDomainNameHere
   dns-server 192.168.20.1 192.168.20.10
   default-router 192.168.1.254
   netbios-node-type h-node
   lease 15

You can look at what's going on with
 show ip dhcp binding
 show ip dhcp conflict
