Wireless CPE and an access method therefor are provided. The wireless CPE includes a control subsystem, an access subsystem, and an interface and control module arranged therebetween. The interface and control module is configured to provide a communication link between the control subsystem and the access subsystem when no master equipment accesses the interface and control module, otherwise, disconnect the communication link between the control subsystem and the access subsystem and provide a communication link between the access subsystem and master equipment. Thus, some users can exclusively enjoy wireless broadband resources while some users use wired broadband resources without additional cost.
