Patent ID: 8599757

Claim:
A plug-and-play wireless network extension system, comprising: a wireless Ethernet extension controller, comprising: a wireless network module providing wireless network access service; a controller-end power-line network bridging module, wherein the wireless Ethernet extension controller uses the controller-end power-line network bridging module to connect to a power socket for data transmission over a power-line communication technology; a controller exploring communication module, for waiting for an inquiry and request from a network device through the power-line communication technology; a user operation and configuration module, providing a management interface for a wireless network configuration; one or more wireless Ethernet extension stations, electrically connected to the wireless Ethernet extension controller, comprising: a station-end wireless network module for providing wireless network access service; a station-end power-line network bridging module, wherein the wireless Ethernet extension station uses the station-end power-line network bridging module to connect to another power socket for data transmission through the power-line communication technology; a station exploring communication module, automatically transmitting broadcast packets to exploring a network address of the wireless Ethernet extension controller through the power-line communication technology; and an automatic connecting means, automatically performing the wireless network configuration as the one or more wireless Ethernet extension stations are connected with the wireless Ethernet extension controller.
