🖥 Error 651 when connecting to the Internet: causes, remedies

What does error 651 mean in Windows when connecting to the Internet?

When this problem occurs, a system message is displayed on the user's monitor screen informing that the communication device used to connect to the network returned an error code. After the appearance of such information on the monitor, most try to call the provider to find out the reasons for the failure, but more often the whole problem is related to the lack of physical connection or incorrect configuration of the network connection on the side user. The appearance of an error means the impossibility of connecting, which is reported by the system with error 651.

Causes of the malfunction

There are several most common reasons leading to the appearance of such a nuisance on the computer. Some of them are associated with physical failures, and some can be caused by incorrect settings:

• damage to the network cable or equipment;
• mismatch of network card drivers;
• failure in the normal operation of the PPPoE client;
• blocking outgoing and incoming connections by a firewall or antivirus;
• the presence of a second network card in the user's computer.

In rare cases, the lack of a high-speed connection may occur due to the fault of the provider (work on the line, equipment failure, preventive measures).

As practice shows, most often the lack of connection arises in connection with the incorrect actions of the a user who unknowingly or accidentally made changes to the normal operation of the operating system in terms of network settings.

What to do if a lack of physical connection is the cause

If the source of the problem is not actions on the part of the provider, fixing the error does not require a lot of knowledge of the operating system from the user. It is important to simply follow the sequence of diagnostic steps to determine the cause and then correct the failure.

Damaged network cable or connector

One of the common reasons for not having a high-speed connection is a damaged network cable. Despite the outer protective insulation, it is quite easy to scratch or tear. This can happen if you have pets that chew on wires. Furniture can also damage the power cable. To eliminate the trouble, you just need to check the wire for integrity. If there is visible damage, replace it with a new one.

Sometimes a failure occurs when the plug falls out. Therefore, another correction method is to reconnect the wire to the corresponding socket on the computer. When connecting, a characteristic click of the lock should be heard.

Failure of the modem or switch

It is likely that the problem was caused by a malfunction of the router itself. To verify this fact, it is recommended to perform two consecutive steps:

1. Unplug the device from the outlet for a few minutes. This is necessary in order to reset the current session. After turning it back on, try to establish a connection again.
2. If there is none, you must try to make a direct connection. This means that the network cable going to the apartment must be connected directly to the PC, bypassing the router or switch.

TOINFORMATION!

With a direct connection, you enter the login and password issued by the provider when concluding a contract for the provision of services.

If it turns out that a direct connection is being made, then we can safely say that the problem of the error is in the router that needs to be changed.

PC network card malfunctions

The third physical problem that can lead to a failure is a problem with the network card. It is likely that a small power surge has occurred, causing a temporary failure in the normal operation of this node. A simple restart of the computer can solve the problem.

You can also make sure that the network card is working properly. There is an indicator light near the connector for connecting the plug, which lights up when there is a network. If it does not light up when the cable is connected, it means physical damage to the card. In this case, the only way to eliminate the malfunction is to purchase a new part and replace it.

How to fix error 651 with incorrect network connection settings

Finding a physical problem is the fastest way to solve the problem and does not require the user to know the internal features of the operating system. The situation is a little more complicated when error 651 becomes the result of a system failure or incorrect operation of the OS. It will take a little more time and knowledge to solve the problem.

Checking router settings and protocols

The simplest and fastest way to troubleshoot a software failure is to create a new connection. This will save the user from a long search for an incorrectly working protocol and will make sure that the reason is precisely the incorrect configuration of the router or router.

You can make a new connection as follows:

1. Go to the "Control Panel" and go to the "Network and Sharing Center" menu. The user will see all available connections. You need to select the one that causes the error 651 and delete it by right-clicking and selecting the appropriate item from the drop-down context menu.
2. Next, press the Win + R combination on the keyboard. In the command line that opens, type the command rashone.exe.
3. These steps are required to invoke the New Connection Settings Wizard. First of all, you need to select the "High Speed" item.

TOINFORMATION!

To complete the setup, you just need to follow the wizard's prompts. When creating a connection, you will need to enter the login and password given by the provider when concluding the contract.

The process is similar when using a wireless router. To create a new connection and configure the equipment, the device must be connected to a PC via a patch cord, and a network cable connected to it that goes to the apartment. Further, through the computer, you must perform the following steps:

• go to the router menu. To do this, you need to type the appropriate address in the browser;
• after accessing the router settings, you will need to open the Internet or Network tab (depending on the device model);
• then you will need to select the type of connection (by default PPPoE) and enter the login and password provided by the provider.

TOINFORMATION!

Most often, the manufacturer places a sticker on the bottom panel of the router, where the login details (IP address, username and password) are indicated. Usually, the admin / admin link is used to access the menu, and the address is 192.168.0.0 or 192.158.0.1

More drastic methods of fixing the arising trouble are resetting TCP / IP settings and changing the type of connection when using a router.

To perform the first action, the user needs to take the following steps:

1. Run command line as administrator (cmd / i).
2. Next, perform a reset with the netsh winsock reset command.
3. Enter the new value for the parameter using the nets hint ip reset c: \ resetlog.txt command.
4. Restart your computer and check network access.

If you use a router and have Windows 10 operating system on your computer, the problem with the inability to log on to the network may occur with a change in the connection type. To set the correct parameter, you need to go to the router, go to the Internet or Network tab and select the correct type (PPPoE). Next, the settings must be saved and the PC rebooted.

Troubleshoot antivirus or firewall issues

Enabled defenders can block access to Internet applications that are considered suspicious. In this case, the correct method of solving the problem is to include this program in the list of exceptions.

TOINFORMATION!

It is not recommended to completely turn off the protection system, since in this case the likelihood of a PC infection increases. To eliminate this cause of the problem, you can turn off the firewall or antivirus for a while and try to log on to the network.

To create an exception in the firewall, follow these steps:

• go to the "Control Panel";
• go to the "System and Security" tab;
• select the "Firewall" item;
• open the list "Allow interaction with the application";
• in the exclusions tab, select the program for which an exclusion will be made;
• the final action will be putting the checkboxes in front of the buttons "Public" and "Private network".

To save the result, you just need to click OK and try to go to the Internet. It will not be superfluous to reboot the computer first.

Updating Drivers

Some of the causes of error 651 include malfunctioning network card drivers. To update them, the most correct way is to visit the site of the node manufacturer and download the latest versions for the device you are using. After completing the process, be sure to restart your computer for the changes to take effect.

Resolving the conflict when there is a second connection

Connecting two parallel network sessions to one computer is recognized by the system as a conflict. In this case, an error may occur. Removing the cable is not enough to fix it. Go to the "Control Panel", open the "Network and Sharing Management" screen and disable one of the adapters through the context menu of the right mouse button.

Registry Actions for Server OS

If the problem occurs when the server version of the operating system is running, then it can be solved by changing the system registry. This action is not the easiest one, but for people who understand the computer, it will not be difficult to make the necessary adjustments:

• open the registry editor with the regedit command;
• find the branch HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ Tcpip \ Parameters;
• on an empty space in the window, right-click and select "Create", then - the DWORD parameter;
• give it the name EnableRSS with a value of 0;
• additionally create a DisableTaskOffload parameter with a value of 1.

TOINFORMATION!

If there is the last line in the registry, the user will simply need to change the value to "one".

After that, you need to restart your computer again for the changes to take effect.

Problems from the provider

If there are problems on the part of the provider, the only way is to wait for the moment when everything will be fixed. The user can get an answer by calling the support hotline. As a rule, if planned work is being carried out, or there were damages on the highway, then the company providing the services tries to fix everything as soon as possible.

Do not be afraid of error 651 appearing. It is not critical and, if the correct sequence of actions is followed, it can be easily corrected. You can see how to fix this problem again from the video presented.
