A method for setting a wireless LAN is provided, which includes receiving a packet, which informs a user that a WPS (Wi-Fi Protected Setup) button of an access point is operated, from the access point; activating a button provided in an image forming apparatus as a WPS button; selecting a button activated as the WPS button; and if the button activated as the WPS button is selected, constructing a wireless network with the access point.
摘要:
A hybrid wired and wireless communication device and a wired and wireless communication method thereof. The wired and wireless communication method includes determining whether a wired communication module has been linked to a wired communication network (72), setting a wireless communication operating mode of a wireless communication module to an infrastructure mode when it is determined that the wired communication module has not been linked to the wired communication network (74), and setting the wireless communication operating mode to an ad-hoc mode when it is determined that the wired communication module has been linked to the wired communication network (76). Therefore, the wireless communication operating mode is automatically set according to whether the wired communication network has been linked to the wired communication module, thereby increasing a user's convenience.

A method, an apparatus, and a machine-readable medium for informing a user about a print error of a wireless printer in a wireless network are provided. The method comprises determining whether data to be printed are not received by the wireless printer server for more than a predetermined period during the wireless printing operation, requesting and receiving wireless communication information on the wireless printer server when it is determined that the data to be printed is not received by the wireless printer server for more than the predetermined period, determining whether a link state or a link quality of a wireless communication is good by analyzing the received wireless communication information, generating print error information regarding the communication between the wireless printer server and a host when it is determined that the link state or the link quality of the wireless communication is bad, and reporting the print error information to the user.
摘要:
An application program may be executed through an Internet protocol (IP) address linkage in an image forming apparatus supporting a peer-to-peer connection. The application program may be executed by performing a method which includes connecting the image forming apparatus to a wireless device through a wireless local area network, driving a soft access point (AP) module of the image forming apparatus so that the image forming apparatus functions as an AP, driving a dynamic host configuration protocol server of the image forming apparatus to allocate a dynamic IP address to the connected wireless device, and linking the dynamic IP address allocated to the wireless device with a static IP address that is preset with respect to the wireless device.
摘要:
A method of controlling a link speed in an image forming apparatus to reduce power consumption of the image forming apparatus by changing the link speed of the image forming apparatus, the method including establishing a link between the image forming apparatus and an external device in a normal mode of the image forming apparatus, determining whether a network environment of the image forming apparatus, which is reconfigured by changing a speed of the established link, satisfies at least one predetermined condition, and disabling a function of changing the speed of the established link in a sleep mode of the image forming apparatus, based on a result of the determining.
摘要:
A method of managing security of an image forming apparatus that supports a P 2 P connection based on a signal intensity includes: measuring an intensity of a signal transmitted from an external wireless device by the image forming apparatus; and controlling an access of the wireless device by the image forming apparatus based on the measured signal intensity.
