Abstract: A method for a WLAN-enabled device to access to a network is provided, including the following steps. An intelligent terminal device acquires a key KEY1, encrypts, by using the KEY 1, access information of a wireless access device that is known by the intelligent terminal device, and then transmits the access information as well as the unique identification information. WLAN-enabled device sniffs and acquires the unique identification information and the encrypted access information, generates the KEY1 based on the unique identification information and a preset key material, and decrypts the encrypted access information by using the KEY1 to obtain the access information. The present invention further relates to a WLAN-enabled device for implementing the method and an intelligent terminal device.
