Problems solved by technology

For example, if a motion picture is transmitted via real-time data communication and displayed on a TV, the user feels that it takes too long to maintain the associated mode
In addition, the time for maintaining the association mode of the wireless LAN is always set by the manufacturer, so that it is impossible to properly adjust the association mode retention time for real-time data communication
[0011] Therefore, in a conventional wireless network system using a wireless LAN, there is a problem that data communication cannot be quickly restored when the channel link is disconnected.

Abstract

An electronic device includes a wireless LAN module performing predetermined initialization when a predetermined setting time is passed after a channel link is disconnected, and a controller initializing the wireless LAN module when the wireless LAN module does not receive a predetermined response from an external electronic device within a predetermined standby time shorter than the setting time, after transmitting data to the external electronic device. The wireless network system and an electronic device can avoid signal interference and promptly resume data communication even when a channel link is disconnected due to the signal interference.

Description

[0001] This application claims priority to Korean Patent Application No. 2004-65563 filed with the Korean Intellectual Property Office on Aug. 19, 2004, which is hereby incorporated by reference. technical field [0002] The present invention relates to a wireless network system and an electronic device, and more particularly, to a wireless network system in which initialization is performed regardless of a wireless local area network (LAN) mode when a channel link is disconnected so as to rapidly resume data communication and electronic device. Background technique [0003] The operation of the wireless LAN is divided into four states, such as on mode, off mode, association mode, and connection mode, which are stored as state data. [0004] The wireless LAN is turned on from the off mode by the user, and a predetermined initialization operation is performed. At this point, look for the optimal channel to ensure stable commu...
