The invention discloses a WIFI (wireless fidelity) network access method, which is applied to a wireless access point, and comprises the steps that the wireless access point sends configuration information including a WIFI network access identifier and wireless access point information to a communication terminal through a bluetooth communication module, wherein the configuration information is used for indicating the communication terminal which receives the configuration information to select a wireless access point according to the identification information of the wireless access point, and accessing a WIFI network according to a WIFI network access password in the wireless access point information. In such a way, the communication terminal can automatically access the WIFI network without receiving input information of a user for multiple times or responding to a human-machine interaction request triggered by the user for multiple times, so that the process of accessing the WIFI network is simplified. The invention also discloses a WIFI network access device, electronic equipment and a communication system.
