Abstract: A user interface is for controlling a computer network. The user interface comprises a device menu, a device selection identifier, function menus, a function selection identifier, and a results screen. The device menu identifies at least some of the devices that comprise the computer network. The device selection identifier provides for selecting one of the devices. The function menus correspond to the devices and identify at least some functions that can be performed in connection with the devices. The function selection identifier corresponds to the function menus that allow an entity to select one of the functions. The user may select one of the devices, and may select one of the functions corresponding to the device that is selected. The results screen displays a result corresponding to a selected function. The user interface can be used in connection with wireless devices or an existing network management systems.
