To remove a network from a zone:
- Go to your Control Panel's Settings menu and click the Network Zones icon.
- Click the label of the zone you want to remove a network from. The screen that appears will show you all networks in the cloud, organized into two lists – those assigned to the zone already, and those that are unassigned.
- In the assigned list, find the network you want to remove, and click the Delete icon next to it.
