Abstract

An electronic device including 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.

Claims

1. An electronic device comprising:

a wireless local area network (LAN) module which performs predetermined initialization if a predetermined setting time passes after a channel link is disconnected; and

a controller which initializes the wireless LAN module if the wireless LAN module does not receive a predetermined response from an external electronic device within a predetermined standby time which is shorter than the predetermined setting time, after transmitting data to the external electronic device.

2. The electronic device according to claim 1, wherein data communication is performed with the external electronic device on the basis of an IEEE 802.11 standard in an ad-hoc network environment.

3. A wireless network system comprising a display and an electronic device, wherein the electronic device comprises:

a wireless local area network (LAN) module; and

a controller which initializes the wireless LAN module if the wireless LAN module does not receive a predetermined response from an external electronic device within a predetermined standby time after transmitting an audio/video signal to the external electronic device through the wireless LAN module.

4. The wireless network system according to claim 3, wherein the wireless LAN module performs a predetermined initialization if a predetermined setting time passes after a channel link is disconnected, and the predetermined standby time is shorter than the predetermined setting time.

5. A method of controlling an electronic device comprising a wireless local area network (LAN) module, the method comprising:

transmitting data to an external electronic device through the wireless LAN module;

determining whether a predetermined response is received from the external electronic device within a predetermined standby time shorter than a predetermined setting time; and

initializing the wireless LAN module if the wireless LAN module does not receive the predetermined response from the external electronic device within the predetermined standby time.

6. The method according to claim 5, further comprising:

performing an operation corresponding to the predetermined response if the wireless LAN module receives the predetermined response from the external electronic device.

7. The method according to claim 5, wherein data communication is performed with the external electronic device on the basis of an IEEE 802.11 standard in an ad-hoc network environment.

8. The method according to claim 5, wherein the wireless LAN module performs a predetermined initialization if the predetermined setting time passes after a channel link is disconnected.
