HI,
I am using cisco 1812W router with IOS c181x-advipservicesk9-mz.124-15.T7.bin.
I am running this router as a DHCP server with pool of 10.0.0.0 / 24. The wireless users connecting to this router gets authenticated by ACS.Once authenticated, they will get IP from router.
The issue that I am facing is, sometimes my laptop gets an IP address from the range of 192.168.0.x/ 24 with GW 192.168.0.1. This IP range is not present in my network.
I have also tried explicitly excluding this range by command "ip dhcp excluded range", but it does not help.
Can any one guide me on this.....

Sounds like you have another DHCP server on the same network, it may be a rogue device.
You may have tried this already but check on the client where its getting its DHCP address from using 'ipconfig/all'
Also I would check the DHCP leases on the 1812 router.
Hope this helps

Has this router been deployed else where previously, check the startup config, If all else fails copy the config, wipe the box completely and then reconfigure the router.
