摘要

PURPOSE: A wireless network system and a method for setting an Internet protocol address and connecting to the Internet by using a wireless LAN card are provided to remove users' inconvenience of having to set a network at an initial stage, save time for setting the network and allow the users to easily use a communication network. CONSTITUTION: A wireless LAN card(200) includes a nonvolatile memory(202) for receiving a wireless network and Internet connection information of a specific position from a user and storing it, and is freely mounted in or removed from a user terminal(100). When the wireless LAN card(200) is mounted in the user terminal(100), the user terminal(100) automatically performs an initial setting of a corresponding wireless network at the specific position based on the wireless network and Internet connection information of the specific position stored in the memory(202), and is connected to the Internet through an access point(301).
