Apparatus and method for determining validity of WiFi connection in wireless communication system

摘要

An apparatus and method for determining validity of a Wireless Fidelity (WiFi) connection in a wireless apparatus is provided. In the method, a query is performed on a specific Domain Name Server (DNS) via a connected Access Point (AP). When a response to the query on the specific DNS is received, a connection to a specific node is attempted via the connected AP. When the connection to the specific node is successful, a valid WiFi connection is determined. The WiFi connection is maintained. Therefore, a WiFi apparatus is allowed to connect to only a valid AP, so that convenience is provided to a user and the WiFi apparatus is prevented from wasting power.
