  • Publication number: 20150201424
    Abstract: A wireless network connection method is provided, in which a first priority level of a first electronic device is determined according to the performance of the first electronic device. A first identification sound of a frequency band of a total frequency band is transmitted, and the frequency band corresponds to the first priority level. A second identification sound from a second electronic device is received. A second priority level of the second electronic device is determined according to the second identification sound. The second priority level is compared with the first priority level. When the second priority level is higher than or equal to the first priority level, the transmission of the first identification sound is stopped. When the second priority level is lower than the first priority level, the transmission of the first identification sound is kept until a host is assigned to implement wireless internet connections.
