The present application provides a method and an apparatus for networking an unmanned aerial vehicle and a system for controlling an unmanned aerial vehicle. The method for networking an unmanned aerial vehicle includes: generating a service set identifier and a password; sending the generated service set identifier and password to a control end by means of short-distance wireless communication; judging the status of a connection to the control end; when the connection is disconnected, returning to the step of generating a service set identifier and a password, where the service set identifier and the password that are generated each time are both different from the previously generated service set identifier and password; and when the connection is not disconnected, continuing to judge the status of the connection to the control end.
