Abstract: A WLAN access device includes a connecting module, a PING detecting module, and a wireless signal control module. The connecting module obtains an IP address from a DHCP. After the connecting module getting the IP address, the PING detecting module sends the PING messages to a gateway, and receives the corresponding response messages from the gateway. The wireless signal control module enables a wireless module of the WLAN access device to transmit wireless signals when the PING detecting module receives the corresponding response messages from the gateway. The present disclosure further provides a method of controlling wireless signals of the WLAN access device.

Abstract: A customer premise equipment (CPE) communicates with both lower-layer and upper-layer network within the LAN that communicates with an ISP server. The CPE searches other CPEs after receiving commands from the upper-layer network and makes port configuration after receiving commands from the upper-layer network, and also configures the default telnet port according to the port number receiving from the upper-layer network. Then the CPE establishes remote communications via the default telnet port with the ISP server. Finally the CPE disabling module disables the telnet service and releases the default telnet port after receiving commands from upper-layer network.
