A wireless network system connecting AP(Access Point) for wireless and wired LAN having a tree structure in an ethernet card connected in parallel for health care and a messaging method using the same are provided to control AP for wired and wireless LAN and reduce delay time generating in data transmission. One of multiple servers checks whether to receive a message(100). If the message is received, the corresponding server checks the receiving side AP is connected to one among its own Ethernet cards(104). The receiving side AP is connected to one among Ethernet cards. A server sends message through the corresponding Ethernet card to the corresponding AP(108). The server sends message to the server in which the receiving side AP is connected(106).
