Method and system for multiple pieces of WI-FI equipment to automatically access specified access point (AP)

The invention discloses a method for multiple pieces of WI-FI equipment to automatically access a specified access point (AP). The method is suitable for multiple pieces of WI-FI equipment of the same manufacturer to automatically connect to a specified WI-FI AP. The method comprises the following steps: 1, defining an encrypted field in a Beacon frame, wherein the encrypted field comprises the connection information of the specified AP customized by the manufacturer; 2, allocating keys capable of decrypting the connection information of the specified AP in the encrypted field to the WI-FI equipment respectively; 3, broadcasting the connection information of the specified AP through the Beacon frame by any AP comprising the encrypted field; and 4, decrypting the connection information of the specified AP in the encrypted field of the Beacon frame by the multiple pieces of WI-FI equipment owning the keys, and connecting the multiple pieces of WI-FI equipment to the specified AP. Through adoption of the method, the multiple pieces of WI-FI equipment can automatically connect to the specified AP at one time. The method is simple in principle, safe in connection, convenient to use and high in efficiency. Centralized management and control of the WI-FI equipment can be realized rapidly.
