In a control method of establishing a wireless network connection through a modulation tone, a first device broadcasts a connection modulation tone, which provides connection data. The connection data includes a network name, a password and an Internet protocol (IP) address. A second device detects the connection modulation tone and demodulates the connection modulation tone to obtain the connection data. Thus, the second device can connect to a wireless access point according to the connection data. Consequently, the user needs not to set the connection data by himself or herself, and the user only needs to move the second device near the first device to establish the connection in a convenient manner.
