Error 651 is the most common of all types of Internet connection problems. Most often, it is with its elimination that the most problems arise, because its occurrence can be caused by many reasons. Some of them can be solved in a few seconds on your own, while others require the intervention of a technician or a call to technical support. The most common causes of errors and ways to solve them will be discussed in this article.
Reasons for error 651 on Rostelecom
Quite often, when error 651 occurs, the user cannot reach technical support and begins to reinstall the system itself, thinking that this will help. But it doesn’t always help, since technical problems may be located not only on your computer. The main causes of the error are:
- failure of the operating system, which may be caused by viruses
- connection blocking by installed Rostelecom antivirus
- incorrect configuration of the router or modem
- damage to the internet cable within the apartment
- problems on the provider side
The main task is to correctly identify the cause of the error, and this is already the work of the technical support service. But while you call her, we will try to consider each point in more detail.
Internet from Rostelecom does not work when connected via a fiber optic line: error 651
In this case, the user receives Internet access thanks to one of two technologies: FTTB or GPON. First you need to do a few checks:
- Have the authorization data been entered correctly (it is worth understanding that if there is even one typo, there will be no access to the network);
- Are the PPPoE connection settings correct?
- Are all devices functioning properly? Whenever an error occurs, you must first reboot both the personal computer/laptop and the router;
- Is the cable connected to the WAL port correctly (it is advisable to use the LAN port);
- Does the Internet from Rostelecom work in your home at the moment?
If changing the settings and rebooting the devices did not help, you should try clearing the registry of “junk.” Nowadays no one does self-cleaning anymore, since there are plenty of free utilities that do an excellent job of this task. One of them is called "CCleaner".
Error 651 due to incorrect operation of the router or modem
Each model of router or modem has a network address for entering the so-called admin panel. Most often, this address is 192.168.1.1 or 192.168.0.1 . Enter it in the address bar of your browser and enter your username and password. In the settings, check the following tabs:
- PPPoE connection settings
- ADSL modem owners should check the VPI and VCI data provided to you by the customer support specialist
- if necessary, make adjustments to them
- save the changes and reboot the device
If these manipulations do not help, then disconnect the Rostelecom cable from the device and reconnect it, since it could simply “move away” from the connector. If this does not help, then check what mode your device is operating in. The most suitable mode is Bridge .
Error 651 when connecting to the Internet via ADSL technology
Today, experts do not recommend a method for connecting to an ADSL network. By all measures, this is outdated technology. ADSL modems, by modern standards, have many disadvantages, but for some they are not critical. Setting up legacy modems is possible using two methods:
- Using a computer
A standard PPPoE connection is used to connect to the network. The first step is to make sure the modem is functioning. Often such equipment loses the signal coming from the telephone line. Look at the signal reception indicator for some time (all modems of this “format” have it). If it blinks, you need to restart the device. The easiest way is to hold down the Reset button and wait a few seconds. If the modem is working properly, the indicator should glow continuously without interruption.
Be sure to check if the cables have come loose. Visually, this is sometimes invisible. Disconnecting the cable by half a millimeter is enough for the Internet to fail.
- Without using a computer (when the device acts as a router)
You must work with the device control panel. You need to make sure that the connection parameters are correct, then turn the transmitting device on and off. If error 651 does not disappear, you need to reset the settings to factory settings (this will not negatively affect the quality of the Internet connection). The Reset button is pressed for about 20 seconds. If the reset does not lead to anything, either the modem has very serious “internal problems”, or it is absolutely working, the problem is not in it.
Chances are that your personal computer and modem are working perfectly, but you still get error 651 when you try to access the Internet. It is quite possible that Rostelecom is carrying out technical work. The provider's call center can provide you with information about this.
What does this error mean?
Error 651 means that the connection via the current network protocol has failed. It can appear both on old networks with an ADSL connection, and on modern twisted pair connections. As a rule, the source of the problem is located specifically in the equipment or in the actions of the provider; less often, this error number is displayed during connection if there are problems with the computer’s operating system itself.
Why error 651 may occur:
- The Rostelecom protocol connection settings of the router, modem or network card of the computer have gone wrong.
- Your computer has two network cards and two connected “Internets” from different providers that interfere with each other.
- Technical damage to the Internet cable that enters your home and is connected to the equipment.
- Technical work on Rostelecom networks, changing connection settings.
- Security on your computer is preventing the connection with current settings.
About the problem
Error 651 when connecting to the Internet means that the operating system was unable to establish a connection via the PPPoE network protocol. It occurs in Windows 10, 8 and 7 - in earlier versions of the operating system it can be found under codes 678 or 815. This is a fairly common error that can be caused not by any one reason, but by a number of different factors. And it occurs not only when connecting to the Internet from Rostelecom, but also from any other provider.
In most cases, it is very easy to fix, so you need to start with basic measures:
- Restart your computer.
- Restart your router or modem.
- Check if the cable connecting the computer to the router or going to the router is damaged. Perhaps it is pinched somewhere in the middle of its length, or perhaps the place where it connects to the connector is damaged.
- Check if you entered the login and password for the network connection correctly.
- Wait a while - the problems may be on the side of your Internet provider, which means they will be fixed soon. You can also check to see if there are any scheduled repairs going on.
Outdated drivers
Error 651 Rostelecom appears, what should I do? In some cases, the cause is the drivers on the network card. What can be done in such a situation?
- Go to the manufacturer's website and find the software you need.
- You can update through Device Manager.
- In it you need to select a network card and open options.
- Search for updates.
- Agree to install the latest version.
- Wait until the procedure is completed.
- You can continue to use the services.
General information about error 651
Error 651 may appear when trying to connect to the Internet. An error notification will appear on the screen, where you will be asked to save it to the log, as well as two actions to choose from: try to connect to the Internet again or close the window without trying to connect again. Before correcting this error, it is worth considering that this number is assigned to it only in current versions of Windows 7, 8 and 10. In older versions of the OS, the numbers were different:
- in Windows XP a similar error was number 678;
- in Windows Vista this error was number 815.
Until you eliminate the cause of this error, you will not be able to connect to the Internet from Rostelecom.
Antivirus programs and problems with them
Failures can occur not only due to hardware, but also due to the use of programs that affect the network connection. These include viruses and firewalls. They block access.
How to deal with the problem?
- It is necessary to disable programs for protection.
- Try going online.
- Got access? Then the reason is additional software.
- You need to go to the program settings and adjust the settings so that it does not block the network.
- Check the functionality of the antivirus.
- Is it still blocking the network? It's easier to uninstall the application and find an alternative solution.
Create a new connection
Often, this step helps to troubleshoot problems with Internet access if the network cable is plugged directly into the computer.
Go to the “Network and Sharing Center” section and in the column on the left, select “Change adapter settings” (usually the third from the bottom). Next, right-click on the current connection and select “Delete” in the context menu.
The next step is to create a new connection:
- To do this, press the “Back” button and select “Set up a new connection” in the Network Control Center menu
- "Internet connection"
- “Create a new connection” – “Next”.
- Now click “High-speed PPPoE connection”, enter the login and password specified in the agreement with Rostelecom, and select a name for the connection.
This simple algorithm of actions can solve the problem of error 651.

Problems with the Internet occur extremely rarely. But sometimes users encounter various difficulties, such as connection failures and error 651. Why does it happen and how to fix it?
Problems with the provider
There may be failures in the operator's network or technical work is being carried out. In this case, users experience temporary restrictions in accessing the Internet. What should I do?
The user personally cannot do anything. We can only wait until the work is completed and access to the network is restored. If the situation does not change for a long time, the Internet does not appear, then you need to contact the operator.
Very rarely problems arise due to failures in the operating system. In most cases, they are resolved after a reboot. If access is not restored, then you need to look for the reason. It is possible that you will have to reinstall the OS.
Absence or incorrect operation of network card drivers
To check the operation of the network card drivers, you need to follow the following path in Windows: click on the “My Computer” / “Computer” icon with the right mouse button. Go to “Properties” - “Device Manager” - “Network Adapters”. Make sure all devices are recognized by the system. If there is an icon next to one of them warning of incorrect operation, right-click on the device and select “Update drivers” from the drop-down menu.
Restart your computer and try connecting to the network again. If restarting Windows does not help, then proceed to the next step.
Reboot and adjust the network device
If an error is detected, any network equipment must be rebooted. For example, a router error with code 651 on the Rostelecom operator requires restarting the modem - this is done through the main control panel of the router or by the simplest method by pressing the Reset button. If the subscriber does not know the connection settings that are adjusted in the control panel, then you can simply turn off the power to the modem and reconnect it to the network. All these actions apply to all other client equipment. When code error 651 occurs when connecting to the Internet, you need to immediately press the Reset button or turn off and reconnect the power to the device - there is a high probability that this will eliminate the problem. After this, you need to restart the PC itself. The root cause of the error may be improper functioning of the network connections on the PC motherboard. In the case when several network cards are installed on the PC, you need to disconnect the unnecessary ones - this is done using the “Device Manager”. You can also disconnect cards in the “Network and Sharing Center” section. But what to do when the error persists? If all network connections have been checked, but the desired result is not obtained, you can try to clean the system registry on your PC using a software method, for example, using the CCleaner utility - this program can eliminate most of the problems that have arisen. As mentioned above, the reason for errors with code 651 from the Rostelecom operator may be the lack of tight contact in the line cable connecting the router and the subscriber’s PC. In such a situation, you need to remove the cable from the ports and wipe all contacts with medical alcohol or regular cologne. There is also a risk of mechanical damage to the network cable - replacement is inevitable.
