Abstract

A method and apparatus for setting a wireless local area network (LAN) based on manipulating a button is provided. In the method, an existing wireless network links with a network that supports a wireless security setup. The method includes storing setup information about a currently associated wireless network if the currently associated wireless network exists, and performing the wireless security setup of the network that supports the wireless security setup, according to the stored information about the currently associated wireless network.

Claims

1. A wireless local area network (LAN) setting method by which a currently associated wireless network links with a network that supports a wireless security setup, the method comprising:

if it is determined that the currently associated wireless network exists, storing setup information about the currently associated wireless network; and

performing wireless security setup of the network that supports the wireless security setup, according to the stored information about the currently associated wireless network.

2. The wireless LAN setting method of claim 1, wherein if no securities have been set in the existing wireless network, a wireless LAN setup is performed using only an identifier of the existing wireless network in response to manipulating a button.

3. The wireless LAN setting method of claim 1, wherein if a WiFi protected setup network supports a security setup level of the existing wireless network, the wireless security setup is performed using the identifier, a security level, and a security key of the existing wireless network.

4. The wireless LAN setting method of claim 1, if no currently associated wireless networks exist, further comprising performing wireless LAN setup based on manipulating a button according to set network information.

5. A wireless local area network (LAN) setting method by which a currently associated wireless network links with a network that supports a wireless security setup without changing information about the existing wireless network, the method comprising:

if the currently associated wireless network exists, storing an identifier of the currently associated wireless network;

generating a security level and a security key in response a user'"'"'s request; and

performing the wireless security setup by using the stored identifier of the currently associated wireless network and the security level and the security key which are generated.

6. The wireless LAN setting method of claim 5, wherein the security level is determined through communication with an apparatus for setting a wireless LAN by manipulating a button.

7. The wireless LAN setting method of claim 5, wherein the security key is dynamically and randomly generated using one of a random number and a random text.

8. A wireless local area network (LAN) setting method by which an existing wireless network is relayed with a network that supports a wireless security setup, the method comprising:

storing network information about apparatuses connected to one another via a wireless network;

converting a security setup of a packet received via the wireless network into a security setup of a destination network by referring to the network information about the apparatuses; and

re-transmitting a packet changed according to the security setup of the destination network to the destination network.

10. The wireless LAN setting method of claim 8, wherein the converting the security setup of the packet into the security setup of the destination network comprises:

decoding the packet by using a security level of the packet; and

encrypting the decoded packet by using a security level for an address of the destination network.

11. The wireless LAN setting method of claim 8, further comprising, after the encrypting of the decoded packet, waiting for a predetermined period of time and re-transmitting the packet if it is determined that an apparatus belonging to the destination network of the packet operates in a sleep mode.

9. The wireless LAN setting method of claim 9, further comprising, after the storing the network information about the apparatuses, forming a network information management table for managing a network information list.

12. A method of setting a wireless local area network (LAN) setup of an apparatus that supports a wireless security setup, the method comprising:

randomly generating a service identifier in response to a user'"'"'s request made by manipulating a button;

scanning wireless LAN apparatuses with which the apparatus that supports the wireless security setup can associate, and randomly generating a security key if the generated service identifier is not identical to a service identifier of one of the wireless LAN apparatuses; and

performing the wireless security setup by using the generated service identifier and the security key.

13. The method of claim 12, further comprising generating a hash key in response to the user'"'"'s request.

14. The method of claim 13, wherein the service identifier and the hash key are dynamically and randomly generated using one of a random number and a random text.

15. An apparatus for setting a wireless local area network (LAN) setup of another apparatus that supports a wireless security setup, the apparatus comprising:

an input unit through which a user'"'"'s selection for the wireless LAN setup is input by manipulating a button;

a storage unit which stores network setup information about apparatuses networked with one another; and

a wireless LAN control unit which performs the wireless LAN setup in response to manipulation of the button, according to information about a setup of an existing network, which is stored in the storage unit, and generates a security level and a security key at a user'"'"'s request and performs the wireless LAN setup in response to manipulation of the button by using a service identifier of the existing network, which is stored in the storage unit, and the security level and the security key, in response to receiving a request for the wireless LAN setup through the input unit.

16. The apparatus of claim 15, wherein the wireless LAN control unit encrypts a received packet according to a security setup of a destination network by referring to the network setup information about the networked apparatuses, and re-transmits the packet to the destination network.

17. The apparatus of claim 15, wherein the wireless LAN control unit randomly generates a service identifier and a security key in response to a user'"'"'s request that is made through the input unit and performs wireless LAN setup based on manipulation of the button by using the service identifier and the security key.

18. The apparatus of claim 15, wherein the storage unit comprises a network information management table for managing a network setup information list associated with the networked apparatuses.

19. A computer readable recording medium having recorded thereon a program for executing a wireless local area network (LAN) setting method by which a currently associated wireless network links with a network that supports a wireless security setup, the method comprising:

if it is determined that the currently associated wireless network exists, storing setup information about the currently associated wireless network; and

performing the wireless security setup of the network that supports the wireless security setup, according to the stored information about the currently associated wireless network.
