If you'd like to change the IP scope that is handed out when users are connecting but still using the CWP so they aren't using your DHCP yet, you can do this by going in to Configure> Open the Network Policy> Open the SSID> Open the CWP object in use> Expand Advanced Configuration> Under Network Settings check the option next to "Customize", and enter the IP scope you would like to use. This can be any scope so long as it does not overlap with any existing subnets already on your network.
