Problems solved by technology

[0014] On the other hand, for example, when communicating with more than three devices, the providing device may want to provide the same communication parameters to multiple receiving devices
In this case, if the communication parameters provided by the providing device to the receiving device are changed every time the automatic setting is performed, more than two receiving devices will not be able to participate in the same network, thereby adversely affecting usability

[0030] Hereinafter, a communication device according to the present invention will be described in detail with reference to the accompanying drawings. Hereinafter, an example using a wireless LAN system conforming to IEEE 802.11 series standards will be described, however, the communication mode is not necessarily limited to a wireless LAN conforming to IEEE 802.11.

[0031] The hardware configuration in a preferred example of this embodiment will now be described.

[0032] figure 1 is a block diagram representing an example configuration of a terminal to be discussed below. Reference numeral 101 denotes the entire terminal. Reference numeral 102 denotes a control unit that performs overall control of the terminal by executing a control program stored in the storage unit 103 . The control unit 102 also controls the setting of communication parameters with other terminals. Reference numeral 103 denotes a storage unit that stores a control program executed by the control uni...

Abstract

A communication apparatus includes: providing means for providing a communication parameter to a receiving apparatus that receives communication parameters; first storage means for storing a first communication parameter that has been set by a communication parameter setting process performed with another communication apparatus; and determining means for determining whether a network established using the first communication parameter exists, wherein the providing means provides the first communication parameter or a second communication parameter that differs from the first communication parameter, based on a result of the determination by the determining means.

Description

technical field [0001] The present invention relates to a communication device, a control method of the communication device, a computer program, and a storage medium. Background technique [0002] In wireless communication represented by a wireless LAN conforming to IEEE 802.11 series standards, there are a large number of setting items that need to be set before use. [0003] For example, in terms of setting items, there are communication parameters required for wireless communication such as an SSID used as a network identifier, an encryption method, an encryption key, an authentication method, and an authentication key, wherein manually setting these communication parameters is difficult for the user very troublesome. [0004] In consideration of this, various manufacturers have devised automatic setting methods for easily setting communication parameters in wireless devices. These automatic setting methods automatically perform setting of communication parameters by s...
