What does "Error 651" in Windows when connecting to the Internet
When you see this problem on the user's screen displays a system message with the information that the communication device used to connect to the network returned an error code. After the appearance of this information in the monitor, most try to call your ISP to find out the reasons for failure, but more often likely the problem is the lack of physical connection or incorrect configuration of the network connection on the side user. The appearance of the error is the inability of a connection, what the system reports an error 651.
failure is accompanied by the emergence of a system message indicating the approximate cause trouble
Causes of failure
There are few of the most common causes leading to the emergence of such trouble on your computer. Some of them are associated with physical failures, and some may be caused by incorrect settings:
- Damage to the power cable or equipment;
- mismatch network card drivers;
- failure in the normal operation of the PPPoE client;
- and blocking the outgoing or incoming connection firewall Antivirus;
- presence in the user's computer a second network card.
Cable damage can occur not only in the apartment, but also outside it, then it is the fault provider
In rare cases, the lack of high-speed connection can occur through the fault of the provider (the work on the line, a hardware failure, preventive measures).
As practice shows, often the lack of connection arises due to incorrect actions of Users who unknowingly or accidentally made changes to the operating system in the normal operation of the network settings.
What if the reason is the lack of a physical connection
If the source of the problem are not the actions of the provider, the correction of errors do not require the user to more knowledge of the operating system. It is important to observe a sequence of diagnostic steps to identify the cause and then fix the failure.
