Three reasons why the router failed to authenticate after setting the PPPoE password

If you are unable to connect using a router for PPPoE dialing, the system log prompts for password validation to fail, and the specific check and resolution are as follows:

One, may be ISP (Network service provider) server failure, if so, please call the ISP directly to ask and solve the problem.

Second, please confirm that the username and password are entered correctly, is not because the CAPS Lock button was accidentally opened, this situation can be resolved quickly.

Third, there is also a situation is the ISP bound computer network card MAC address, which is also the most complex, because some areas ISP will be installed broadband users to bind users to the Internet Computer network card MAC address, only the computer can be bound by PPPoE dial-up Internet access, other devices can not dial.

You can solve this problem: a single computer can dial the Internet access router configuration interface-network parameters ――MAC address cloning, click "MAC Address Clone" to the top and bottom MAC address, and then to operate dial-up access to the Internet.
