Password-free WiFi (Wireless Fidelity) authentication method based on dual-channel wireless router or AP (Access Point)

The invention discloses a password-free WiFi (Wireless Fidelity) authentication method based on a dual-channel wireless router or an AP (Access Point). The method is characterized by comprising the following steps that the wireless router or the AP simultaneously sends two ways of signals, wherein one way is an authentication signal and the other way is a normal signal; and when mobile equipment enters a coverage area of the authentication signal, the authentication signal obtains an MAC (Media Access Control) address of the mobile equipment through scanning a request signal of the mobile equipment and binds the MAC address in an access control list of the normal signal to complete authentication. The method has the following beneficial effects that the wireless router or the AP can obtain authentication through a closer way without setting a password, so that the trouble for setting the WiFi password is avoided, and meanwhile, the inconvenience for sharing and changing the password cannot occur.
