How to solve the broadband 651 error.

**The emergence of 651 means that the broadband provided by the network operator cannot be connected to the computer normally, and the cause of the failure is nothing more than the line, equipment, and network card, so we only need to check one by one, and we can find the problem.

1. Line failure

The broadband used by the user at home is provided by the network operator, and when the network line of the home is faulty and the external device cannot recognize the network, the user will appear error 651 when dialing up.

This problem often occurs after a power outage or power outage, because it takes a certain amount of time for the network operator's equipment to restart, protocol allocation, and device identification, and if the user dials up at this time, a similar error will be prompted.

In this case, there is no need to worry, and it will automatically recover after the device reboot is completed.

Second, the drive failure

Under normal circumstances, the user dial-up will not appear similar error prompts, but if this kind of prompt appears, and there has been no power outage or power outage before, then it may be caused by a "drive failure".

No matter what device is connected to the network, you need to configure a network card inside the device, if the driver of the network card fails, it will cause the broadband dial-up error of 651.

In this case, you can re-drive the network card, or directly replace it with a new drive-free network card, which can solve the problem.

3. Optical modem failure

If the broadband dial-up error **651 still occurs after eliminating the external line fault and re-driving the computer network card, then it may be caused by the failure of the optical modem.

You can further observe whether the indicator light of the modem works normally, under normal circumstances, the modem will not be damaged, but there will be a crash.

In this case, turn off the modem directly, wait for 1 to 3 minutes before turning it on, and then perform broadband dialing, and similar prompts will not appear.

Off topic:The reasons for the broadband dial-up error 651** are not limited to the above three, when the computer system fails, such as viruses, Trojan horses, accidental deletion of files, etc., it is also possible to cause the computer to be unable to connect to the Internet, this situation is either to repair the file, or to carry out virus killing, or to redo the system, there is no other way.
