The "Error 651" displayed on broadband Internet access is mainly caused by the failure to connect the user's terminal computer with the Netcom central office equipment, which is generally divided into five situations: "network cable failure", "modem failure", "network card failure", "modem itself setting", and "network operator problem". Here's how to deal with such cases:

1. Please replug the network cable and ** cable and restart the modem test;

2. Please disable the local connection first, and then enable the local connection;

3. Please reinstall the NIC driver;

4. If you use a router, please remove it, and dial test it on a single computer.

If the problem is still not solved, you can contact the local customer service for feedback.

The reason for the computer connection wifi error 651 is caused by a system error, and the specific solution steps are as follows:

If error **651 occurs, it is recommended that you troubleshoot the problem from the following aspects:

1. Restart the modem and plug in the optical fiber connector.

2. Judge whether the status of the modem indicator is normal, if it is abnormal (the modem lights up red, the PON light flashes, and the indicator light is abnormal), you can call the local 10086 for broadband fault reporting;

3. Remove the router and directly connect to the optical modem to dial-up to connect to the Internet, if the dial-up connection fails, you can further feedback and deal with it through the broadband fault reporting center;

4. Reconfigure the router.

Still the same can't be solved, I hope there is a very correct answer.
