A very “informative” error message is observed by modem users and wireless routers. Error 651 Windows 7 and how to fix this error is the subject of our conversation today. A message with the text “The modem or other communication device has reported an error” will indicate that the Miniport WAN PPPoE or other high-speed connection has failed.
The equipment, which can be a modem, refuses to receive and transmit data to us. This failure was observed by users of modems of the most different manufacturers operating in networks various operators. One must think that the error does not depend on either one or the other.
No single reason for this failure has been formulated, but many recommendations for eliminating it have appeared - from the simplest to the more complex. The main thing is to understand that there is no need to reinstall the system in the current situation.
Let's start with the simplest recommendations. You need to follow them exactly, otherwise you will be responsible for the consequences yourself. Before getting into the equipment settings, it makes sense to perform some checks, with a description of which we will begin to present our instructions. So, let's roll up our sleeves and get to work.
Simple tests
First, let's do this:
Now let's move on to more subtle aspects of our problem.
We struggle with TCP/IP and the network card
In a situation like ours, resetting TCP/IP settings sometimes helps. For this purpose, Microsoft offers special utility, which can be downloaded from: http://support.microsoft.com/kb/299357.
You just need to remember to reboot the computer after it runs. If this recommendation does not help, then search the Internet and install the latest drivers. network card computer.
You should look for them on the card manufacturer’s website (if we're talking about about a desktop PC) or on the laptop manufacturer’s website (if we are talking about a laptop).
You can do the following:
- Launch Registry Editor.
- Go to the section "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters".
- Create in it new key with the name "EnableRSS" and make it null.
- Create a new key named “DisableTaskOffload” and make it one.
Error 651 when connecting to the Internet is a common malfunction that is localized in Windows environment 7, appears a little less often in the “eight”. The system may display an error when connecting to a high-speed network or Miniport WAN PPPoE. In this case, the subsequent connection to the network is interrupted. Next, we’ll look at the reasons why error 651 appears, as well as all the working ways to resolve the failure.
The connection cannot be configured for one of several reasons.
- A connection to another network is configured (or the Internet is completely absent, there is no cable in the connector). No matter how trivial it may sound, often the cable is simply missing from the socket: it fell out, they forgot to switch it from another device, or there is poor contact. You can check the presence of a connected cable by clicking on the connection icon in the lower right corner.
- There was some kind of malfunction in the functioning of the PPPoE client. This problem lies in the way Windows works. Temporary and random errors are often found in the system, so you definitely shouldn’t rule out this problem. Test method: re-create an Internet connection and launch any page in a web browser.
- Connection failure with error 651 occurred due to correct operation antivirus software, this also includes a firewall. The constant invention of newer and more powerful computer protection tools leads to unexpected problems For example, antivirus programs can block necessary system components. To understand whether this is the case, you should temporarily disable the antivirus with the firewall and check whether connection is possible at this moment.
- Two network cards are installed. If connected to system unit pair of network cards with different connections, then failures may occur. One of the connections will start working correctly, and the second will constantly generate an error.
- A faulty network card driver or incorrect connection settings are very common causes of problems. There is a high probability that the virus system administrator, a child or something else, or someone changed the settings of system files.
- The Ethernet cable is damaged. There are many small wires inside the cable; their damage makes it impossible to set up the connection. Another problem may be incomplete crimping of the cable or breakage of the clamp. By the way, we cannot exclude the risk of damage to the external cable that comes to the house or the provider’s equipment.
- Temporary difficulties on the part of the provider. You can call the Call Center and find out if they have technical problems.
We will not consider special cases, because error 651 is also typical for Rostelecom, MTS, TTK and others. Error 651 can also appear in Continent-Up programs and similar security products. In any case, the ways to solve difficulties are the same.
How to fix connection error 651?
Error 651 The modem or other communication device reported an error - this is primarily an OS problem, which means it can be fixed manually. The methods to restore network functionality are almost identical for each version of Windows, although some implementation methods differ.
Reset with re-configuration of network access parameters
This method allows you to reconnect your computer to high-speed Internet. However, it is only applicable in cases where it is not used additional equipment for accessing the network: modems, smartphones, routers and similar devices.
How to turn on the Internet with error 651:
- Right-click on the connection icon and click on the option “Network Center...”.
- We go to the “Change parameters” page, from here we can start managing connections.
- We find the problematic connection and, by right-clicking, activate the “Delete” command.
- Let's go back one step and click on the create connection button.
- In the first window, click on the first item with “PPPoE” and enter the connection data.
If the cause of the failure is incorrect setting or a malfunction of the PPPoE client, the problem should disappear after re-creating the connection. Often the problem turns out to be more complex, so if the procedure is unsuccessful, you should not be upset.
Changing TCP/IP settings in Registry Editor
Initially, the method was intended to correct a malfunction in Windows versions for servers. However, many reviews show its effectiveness in other versions of the OS.
How to fix error 651 Windows 7 when connecting to the Internet through a router:
- Press Win + R and run the regedit command.
- Go to the following path in the registry: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters.
- In the area on the right, right-click and click on the option “Create DWORD value (32 bits)”.
- Set the parameter name to “EnableRSS” and set the value to 0.
- We create another similar parameter, but in the name we indicate “DisableTaskOffload” and the value 1.
- Close the working window and restart the computer.
- We check the ability to connect to the Internet.
Updating your computer's network card drivers
One solution involves installing new drivers. Its peculiarity is that individual drivers may not exist. In this case, you will have to install a new one software For motherboard. Such drivers are always posted on the manufacturer’s website.
Important! In some cases, removing the driver and reinstalling it from the kit that comes with Windows helps. Just go to “Device Manager”, select “Update drivers...” via RMB, click on “Search for drivers on this computer”.
Reset network settings, remove broadband connection and set up again
A similar procedure has already been performed in the first method, so we will not go into detail about the method of deleting and then creating a connection. The peculiarity of the method is to pre-reset TCP/IP settings. Sometimes simply re-establishing the connection doesn’t help, but resetting the parameters does, so it’s definitely worth a try.
Instructions:
- Press Win + R and paste cmd, then Enter.
- Paste the command into the console: netsh winsock reset.
- After executing the previous command, insert the following: netsh int ip reset c:\resetlog.txt.
Now we can return to the first method.
Error 651 as a result of incorrect operation of network adapters
It is possible that the network is unavailable solely because the network card is currently disabled at the software level. It’s very easy to turn it on, that’s what we’ll do now.
- Go to “Device Manager” (right-click “Computer”, select “Properties”, click on the desired menu on the left).
- Open the “Network adapters” list.
- If there is a red cross next to the problematic connection, then right-click and select “Enable”.
Antivirus and firewall problems
Even modern means of protection against viruses, such as antivirus, and unwanted connections from outside (firewall), do not work imperfectly. They could block the connection, considering it dangerous. To find out if there is a problem in the antivirus, go to the tray, right-click and disable it for 10 minutes. We check whether we can connect to the network.
If this does not help, you should temporarily disable the firewall, which we can find in the Control Panel. We try to connect again. Using these methods, it is easy to determine the cause of this failure. If any of the above actually causes a failure, then you need to create an exception for the connection to work correctly.
Availability of a second network card
If your system has several network adapters installed, you should choose one of them. How to do this? Go to “Network Control Center...”, and in the “Changing adapter settings” section, disable one of the active networks. The second connection should work automatically, but sometimes it also needs to be rebooted. First we disconnect and then re-enable the connection.
Problems with the provider
If all of the above manipulations did not produce anything, then this indicates the correct Windows operation. The malfunction may be caused by problems with the provider. It's worth taking a few minutes to clarify this issue with a support representative. Even during the conversation, it is worth requesting a port check. Very soon an employee of the provider will let you know if they have any glitches. If this is true, you should wait for completion technical work or call a network setup specialist.
While surfing the Internet, the user may encounter an error message 651, indicating a malfunction network equipment. Not knowing how to deal with trouble - error 651 when connecting to the Internet, many users decide to take drastic steps in the form of reinstalling the OS, which should not be done. In this material, I will talk about the essence of this problem, list the causes of error 651 in Windows 7 and 8, and also tell you how to get rid of error 651 on your PC.
Error 651 occurs when the protocol fails PPPoE responsible for the network connection. This protocol PPPoE (Point-to-Point Protocol over Ethernet) is used by many Internet providers, allowing them to establish a direct connection between communication nodes, provide connection authentication, encryption and data compression.
Error 651 when connecting to high-speed Internet is a frequent “guest” on Windows 7 and 8 versions; it also occurs on other operating systems from Microsoft, on Linux (with a different name) and on other systems.
On Windows XP, the analogue of this error is error 678, and on Windows Vista – 815.
Error 651 when connecting to the Internet: causes and solutions
Error 651 can be caused by many factors, both hardware and software. Below I will provide a list of them, and at the same time I will provide options for eliminating the problem. Before delving into the hardware and software components, try simply rebooting your computer and router, and also calling your provider and asking if the cause of error 651 is any repair work, equipment failures, etc. It is quite possible that the reason is not yours, but his.
Physical damage to cables
First of all, it would not hurt to make sure that network cable and connectors (RJ-45) are not damaged and are functioning normally. It happens that a child, a pet, or the carelessness of a user damages the power cords and plugs, which has the saddest effect on the Internet connection. It happens that the plug simply comes off, so you need to check the tightness of the connector to the network connector by first removing the plug from the socket, and then plugging it back in until you hear a characteristic click.
And yes, if you are using PPPoE via wireless connection, make sure you have it turned on Wi-Fi adapter on your PC.
Incorrectly specified parameters
If error 651 appeared the very first time you connected to the Internet, then perhaps the problem is due to incorrectly set parameters, for example, in VPN connections the VPN server data is often incorrectly specified.
Problems with the network card
The network card may also be the cause of error 651 when connecting to the Internet. Moreover, this applies both to problems with its drivers and settings, and in the event of its physical breakdown. In case of false installed drivers Unknown devices will appear in the device manager, this is easy to track visually.
To resolve problems with drivers, you need to download and install the latest versions from the website of your PC's motherboard manufacturer. You can also try the opposite option - remove previously installed drivers, and then update the network card drivers through the device manager (device manager - network adapters - right-click on the name of your network card - update drivers).
There are also cases when a user has two network cards in Device Manager instead of one. Try disabling the one that is causing problems (Network and Sharing Center shared access— Changing adapter parameters - right mouse button on network device– Disable).
RASPPPOE client failure may cause error 651
Malfunction of this client responsible for the network connection is common cause error 651 occurs. To deal with this problem, you need to delete and then create again high speed connection. To do this, go to the Network and Sharing Center, select the high-speed connection that is associated with error 651, right-click on it and select “Delete”.
After deleting, we return to the Network Control Center, select “Set up a new connection or network” there, then select “Connect to the Internet via PPPoE” and enter your login and password (authorization). Let's try to connect again.
Alternatively, you can create a high-speed connection by pressing the Win + R keys, enter rasphone.exe in the window, select a high-speed connection, and then enter identification data.
I’ll note right away that this point is relevant if the computer is connected to the Internet directly, via RJ-45, otherwise you need to look at Wi-Fi settings router.
Antivirus and firewall
To check whether your antivirus and firewall are to blame for the 651 error, try turning them off for a couple of minutes, and then check your ability to connect to the Internet. Temporarily disable the antivirus through its settings, and you can disable the firewall through the control panel - system and security - Windows firewall– turn Windows Firewall on and off – turn off Windows Firewall. After completing these steps, restart your computer.
By the way, network connection problems can be caused by various virus programs. Check your computer for viruses using powerful antivirus programs Dr.Web Cureit level! etc. Viruses can also cause and.
TCP/IP errors
Problems with TCP/IP settings may be to blame for the appearance of error 651 when starting an Internet connection. To reset the protocol settings, just go to the Microsoft website and select your operating system, download special program to reset the specified settings. After downloading it, run it and then restart your computer.
You can also try go to the registry(press Win+R, enter regedit in the window that appears and click “OK”). Go to the address HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters, right-click on any empty space on the right, click “Create” and select “Dword parameter (32 bits)”. We call it EnableRSS and set the value to 0. In the same way, create the DisableTaskOffload parameter with a value of 1.
It would also be nice disable IPV6(the sixth version of the Internet protocol), which can save us from the error in question. Go to “Manage networks and sharing”, then go to “Change adapter settings”, select your network connection, right-click on it - properties, and uncheck “Internet Protocol Version 6”.
Registry problems
It happens that the cause of the problem - error 651 when connecting to the Internet is a blockage system registry. Use programs like CCleaner or TotalSystemCare to scan and repair damaged Windows registry.
You can watch the video to see how to deal with error 651:
Conclusion
The causes of error 651 can be many different factors, both software and hardware. Before dealing with all the variety of their features, I would advise you to consult your provider - it is quite possible that the cause of the malfunction is the dysfunction of its equipment. And only then, having checked the equipment for mechanical damage, you can start searching for software faults, changing TCP/IP settings, creating a new PPPoE connection and performing other actions specified in this article. If you feel you lack the qualifications to fix error 651 when connecting to the Internet, write questions in the comments below.
Probably many users computer systems Those who use Miniport WAN PPPoE technology or a high-speed connection to connect to the Internet sometimes encounter an ambiguous problem when, instead of the expected access to the Network, a failure message 651 (connection error) appears on the screen. What is this and how to fix this situation? Looking ahead, we immediately note that this is done quite simply.
when connecting): what is this?
First, let's consider the nature of such a failure. Typically, the message text indicates that the modem or router is returning an error when trying to use its settings to connect.
In other words, there is a problem either at the physical or software level that is blocking access. We will not go into detail describing the technologies themselves used to create or establish a connection, but will focus more on the reasons that cause such failures and the simplest methods for correcting them.
Reasons for the error
It goes without saying that there can be quite a lot of reasons why error 651 occurs when connecting to the Internet (Windows systems are taken as an example). From all this diversity, we can single out only those that occur most often and are, so to speak, the main ones:
- damage to equipment and cables at the physical level;
- incorrect operation of the PPPoE client;
- availability of dual network connection;
- connection blocking by antiviruses and built-in Windows tools;
- incorrect parameters in the router settings, etc.
Based on what is presented in the list, we will look for a solution to resolve failure 651 (connection error) for each specific case.
If physical damage is present
First of all, if suddenly a computer or laptop displays warnings of this kind, you should not immediately look for the cause, say, in viruses or in a settings “glitch” network connections. Everything may turn out to be trivially simple: maybe the network cable is damaged, maybe there has been a power surge, maybe the connectors are loose somewhere, but who knows what?
Naturally, it is advisable to check all components or “ring” the cable. However, a simpler option often helps. First, in the warning window, click on the line asking you to reconnect. Who knows, maybe it was a momentary glitch. If this does not help, you can try to completely reboot the computer terminal and, in this case, between turning off and turning on the router again, you need to pause for at least 10 seconds to reset the settings, and then wait full load. If this is not done, the system will again display a message like “Error 651 when connecting to the Internet.” On the other hand, this approach may not help if the initial problem of communication failure is much deeper. Let's see what else it could be?
Error 651 when connecting to the Internet: RASPPPoE client failed
When used for creation, failures of this kind are most often observed in the operation of specialized modules, including the client responsible for PPPoE.
Let's take a closer look at this client. Typically, the primary method to correct the situation is to create a new connection.
To do this, you need to use the Win + R key combination, which opens the “Run” menu, where the rasphone.exe command is written in the line. Next, you should select one of three options (for PPPoE, a high-speed connection via modem or DSL is used), after which you just need to follow the instructions of the “Wizard”.
Accordingly, the newly created connection must be checked for functionality. If connection error 651 is also observed in the new connection (Windows 7, for example), you will have to check some parameters and settings. First of all, make sure that the router is turned on and Wi-Fi module on a computer or laptop. Perhaps the wrong parameters for VPN networks are set, etc. But first things first.
Presence of a foreign network
One of the reasons for such failures may be the presence of a second connection, for example, when two network adapter with two parallel communication sessions. In this case, Windows 7 interprets failure 651 (Internet connection error) as an internal conflict when one connection takes precedence over another (in particular, for cases where services are provided by two different providers).
Remember, if you simply disconnect the cable from one network card, there will be no benefit. To do this, you need to go to the network and sharing management section and disable one of the adapters there (menu for changing adapter settings). However, you should not delete it in Device Manager; this may have a negative impact on the system as a whole.
Antivirus and firewall problems
Very often there may be a situation where the connection is blocked for some reason at the level of anti-virus software or the Windows firewall. In such a situation, you can first try disabling the antivirus for a while (many packages provide such a function). However, as practice shows, the firewall is more different here for the worse.
This is something that should be turned off completely. To do this, use the standard “Control Panel”, where you select the appropriate section. The system will issue a couple of warnings, but you should not pay attention to this. By the way, many may wonder why it is necessary completely Yes, just because adding an Internet connection to the list of exceptions will not work in any way. This is not an “exe” or any other executable program file.
Incorrect router and protocol settings
Now let's look at the most common problem, when the router settings go wrong, and the system reports that connection error 651 has occurred. How to fix this situation? First you need to check basic settings the same router.
You can enter them through any of the Internet browsers by entering address bar either 192.168.0.1 or 162.168.1.1 (it all depends on the router model). In general, this address can be found on the label below. There you can find out your login and password, if any.
First of all, you should pay attention to the VPN server address (for PPTP and L2PT connections). In addition, for ONT terminals on the router you need to use the “transparent bridge” mode (Bridge), otherwise the system will again display a failure message 651 (connection error) when trying to connect.
Next, you should compare the TCP/IP settings with those provided by your provider when connecting. As a last resort, you can try setting automatic detection and also disabling the use of proxies for local addresses.
Additional actions with the registry for server operating systems
Failure when connecting to the Internet), of course, can also occur on server versions of Windows. In particular, this applies to modifications of Windows 2003 Server. Here the specifics of fixing the problem are somewhat different, although the above methods sometimes help.
But in this case, it is better to use the system registry editor, called by the regedit command from the “Run” menu bar (Win + R), where you need to navigate along the HKLM tree branch through the SYSTEM, CurrentControlSet sections and then to the Parameters folder located in the Tcpip directory.
Here, you first need to create a DWORD parameter called EnableRSS and assign it the value 0, and then in the same section - a DWORD parameter called DisableTskOffload with a value of 1. If this particular parameter is already in the registry, you just need to change the value to one. After this, the computer terminal must be restarted for the changes to take effect.
Bottom line
In general, only the most typical cases of type 651 problems are considered here. Situations where problems arise on the part of the provider were not considered (here the user cannot do anything). Also, situations where a reinstallation or update may be required were not taken into account network drivers. Otherwise, as can be seen from all of the above, the problem can be solved quite simply.
Hello friends! Do you have error 651 when connecting to the Internet and don’t know how to fix it? In this article I will tell you in detail what I know about it and how I fix it. By the way, my name is Zhenya, and you can ask any questions in this article in the comments. Ask all questions there or in the (contacts) section. Well, let's get started?
Just recently, an acquaintance of mine called me and asked me to correct this error; I didn’t know how to do it yet, but after surfing the Internet, I found the answer and am sharing it with you.
Error 651 when connecting to the Internet
Let's look at several options to fix this problem. But first, watch the video, it also has the answer.
- From the very beginning, you can call your provider and report this error. It may be that they created this error 651 when connecting to the Internet and they will fix it as soon as possible. But as we all know, most of the operators there themselves do not know anything, and all they can advise is to restart the computer and see what happens. But this option doesn’t suit us, right?
- If the operator did not help you, you can simply delete your Internet connection and create it again. I think you know how to do this? If not, write about it in the comments, and I will answer you by email.
- Sometimes an option like reinstalling the drivers for the network card helped me.
- If you have an ADSL router or Wi-Fi installed in your home, I advise you to read the article, but this is after you have corrected error 651.
- You can also restore a checkpoint, that is, roll back the operating system a week or a couple of days ago. I'm sure you know how to do this.
- Well, let's move on to the real solution to this error, so repeat after me. Click on the start button> run> and enter the command regedit there after that we will need to dig a little into the registry, don’t be afraid, it’s not scary. This is how I’ll write it now, go through the registry branches HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters as soon as you reach the last branch of the section (Parameters) create a DWORD parameter there and point to the name EnableRSS and don’t forget to specify the value ( 0-zero). OK! Let's move on, now we need to create another DisableTaskOffload parameter with the value (1-one). And after completing all these operations, you can safely restart your computer and everything will work.
I really hope that the article error 651 when connecting to the Internet helped you. Well, as I said earlier, you can ask any questions that you still have in the comments, and I will definitely answer you!
