A network error detecting method checks if a network connection device has an Internet protocol (IP) address, if domain name mapping of web pages is correct, and if data communication between a web browser and a web server is correct. Accordingly, the network connection device informs the web browser of an IP address error, a domain name mapping error, or a data communication error. The web browser displays the network errors to users when the network errors are detected.
