An example of failure solving without circuit

The author of a friend of the home is railcom ADSL broadband Internet access, as a result of the addition of a notebook computer, then purchased a Tp-link wireless router, according to the instructions after the installation of two machines can normally access the network.

But a few days later my friend called me for help: Neither machine was able to surf the Internet. Rushed to the scene to carefully check: wireless router's several lights are still normal flashing, and the two computers can also access each other, you can initially determine the local network is no problem, and then remove the router, use the desktop direct dial-up Internet access, but also can successfully log on the Internet, which shows that ADSL cat and CRC Network also no problem. Next check the network cable connection, friends said after installation has never moved the network cable, after the inspection did not find any problems. After careful analysis, the router is the largest suspect, find instructions, restore the factory value of the router, after the installation, in the IE Address bar input: 192.168.1.1, enter the router after the main management page, in the network parameters/wan Port Setup Project WAN interface type selection: PPPoE, After filling in the Internet account and password, click on the link button, but the screen is only refreshed, the system still failed to connect (see Figure 1). After viewing the system log, it is found that the system gives back the username or password incorrectly after sending a connection request, causing the connection to fail. However, the username and password are normal dial-up, which means there is no problem with the username and password. It's just so weird.

Is it that the CRC has banned routers from sharing the Internet? Quickly drive the cat online, there is no relevant news. At this time think of the official website of Tp-link, that will have relevant instructions? With doubt and hope to click on the enterprising, finally found in the troubleshooting solution to the problem: in the network parameter/mac address cloning in the current management of the PC's MAC address cloned to the router (see Figure 2). Following this method, the strike router finally dials merrily.

In fact, in the face of some difficult problems, the Internet to find a solution is not suitable for a shortcut!
