Abstract
The invention belongs to the field of wireless communication. In the design, the self of a bridge can try obtaining an Internet protocol (IP) address after uplink connection is automatically detected by the bridge so as to check whether the function of a dynamic host configuration protocol (dhcp) server is provided by an uplink wireless router or not; if an IP can be obtained, a self dhcp server is just closed; and the IP address is automatically obtained anew by a computer. When the IP address is obtained anew by the computer, the IP address cannot be automatically obtained anew by a connected wireless client terminal through a general bridge; and moreover, a request for enabling the client terminal to update the IP address is not sent out actively by any server yet according to the interactive information of a dhcp protocol. According to the design, the IP address is released by the computer through restricting the association of the client terminal for a period of time when the wireless client terminal is disconnected, and then the IP address distributed by the uplink wireless router can be updated when the client terminal is associated anew. The aim that the operation of surfing the Internet can be realized without manually modifying the address mode of a network card is achieved, and a simpler method is provided to most of users who do not quite understand the network.
