Abstract

A method, control device and computer program product for remotely controlling wireless network devices broadcasting a wireless menu request from a control device to electronic devices connected to a wireless local area network (LAN), receiving a wireless menu response from one of the electronic devices, selecting the one of the electronic devices, and establishing a control connection with the selected electronic device via the wireless LAN. Broadcasting may include transmitting a menu request to a wide variety of electronic devices, or only electronic devices capable of communicating using a predetermined protocol compatible with the control device, such as http. The wireless menu request may be transmitted at a predetermined power that is adjustable to change the communication area of the wireless LAN. Where a plurality of the wireless menu responses are received from a plurality of electronic devices connected to the wireless LAN, the electronic device is selected by displaying a list of the plurality of electronic devices, and selecting one of the plurality of electronic devices based on user selection from the list. The list may be continued on multiple screens and in a predetermined order.
