The computer gives error 651 when connecting the modem. Reinstalling the NIC Driver
Connection failure with code 651 - this is an error that a technician can issue when connecting to the Internet, which means that you or another user tried to unsuccessfully Establish a network connection through the WAN Miniport port (PPPoE protocol) at high speed.
Often we get notification"Modem or other communication device reported an error." Most often, this error occurs for those users who work with Windows 7 and Windows 8. For Windows XP users, the analogue is error 651, in some other operating systems error 678 and 815 .
This problem may arise from provider(especially for byfly, ttk, dom.ru, continent up, ufanet and others), and through the fault of himself user. And if the “Internet provider” can affect the quality of the signal in time or try to quickly fix the error, then the user who did not turn off the router or modem from the network during a thunderstorm or allowed the cat or children to pull out, gnaw through the wire is responsible for the network.
Frequent error in Windows 7
Those who use Windows 7 may encounter error 651. To remove it, you need to open device Manager and in case of incorrect operation, the window will display not only the driver of your network card, but also others unknown driver system.
The appearance of this error is most often associated with the presence on the PC viruses. Also, the reason for the lack of Internet may be initially incorrect installation drivers. In any case, the user is advised to seek help from a specialist or to remove unnecessary drivers on their own, then reboot and scan the entire PC for virus infections. You can still verify computer available system errors and fix or delete them.
Minor bugs in Windows 8
A network problem may occur if the user has a system installed 64-bit version. In order to fix the problem, it is enough to change the 64-bit version to the 32-bit one. But don't ignore standard ways getting rid of the problem that we described above. Note that the presence of an error also displays the interface itself differently, so the same error may look different.
Features of the error in Windows 10
If you are using Windows 10 and encounter error 651 when connecting to the Internet, then the cause of its occurrence may be an incorrect installation drivers network adapter.
A more or less advanced PC user can fix this problem on their own. To do this, open a window with the properties of the network adapter on the computer and uncheck all the checkboxes, except for the item " IP version 4 (TCP/IPv4)". After - restart the modem and try to establish a connection again.
Error on other operating systems
An error with connecting to the Internet can also occur when working with others operating systems (for example, Linux or Windows Vista, Windows XP). Note that if the Internet is not available for a user with Windows XP, then the system will issue error 678 instead of 651, although they are similar. And for Windows Vista users, it will be indicated by an error 813 . But all this is treated as one and also error 651, which the user can fix on their own using the tips that we have indicated.
Troubleshooting Methods
You can get rid of error 651 when connecting to a network on most operating systems yourself using a number of methods described below.
Recreate connection. Check the cable connection to the PC or laptop. It may be that the cord was simply pulled out or it fell out.
Also pay attention to connector(the connector itself, which is included in the socket). When connected to the network, it should be highlighted in green or orange. If the connector is not lit, then it is damaged and this may be the reason for the lack of Internet.
Failure can also be caused by Withfight settings. Finding the cause of the failure is difficult, and it takes a lot of time to spend on it. Way out - creating a new connection.
On the network connection icon, left-click and select "Network and Sharing Center". Then select the function Set up a new connection or network». 
Then select " Internet connection” and then open “ high speed(with PPPoE)”, then enter your login and password(they are indicated by the provider at the conclusion of the contract) and select the button " To plug». 
But this troubleshooting method is only possible if your Internet is connected to the PC using a cable directly, and not through router.
Having a second network. This happens when the user's home network is connected to the second network card. Then with the first connection to the network and there may be problems.
Here you need to know exactly how many network cards are on the PC. If one - then this solution to the problem excluded, and if there are two, then you need to turn off the second board. To disable the board you need to open Network Control Center and sharing and click on " Change adapter settings", after - disable his.
Another reason for failure is security system failure. Then the system may issue a connection error due to the incorrect operation of the antivirus and firewall. To troubleshoot, you need to disable all antivirus programs and reconnect.
Error 651 may occur due to incorrect operation of the built-infirewall. This may cause a network outage. To disable firewall operation open the menu " Start» and select the function « Control Panel". Then select " system and safety” and select from the list - “ Windows Firewall". In the new window select " Turn Windows Firewall on or off' and check the box ' Disable windows firewall
". Then exit the window and restart your computer.
Another likely reason for the lack of a network is problemWithprotocolTCP/IP. In order to troubleshoot the problem, the user must open an Internet browser window and on the Microsoft website download kb update 299357. After, run the program and wait for the system to update the protocols on its own. When the program ends - reload computer and try connecting to the network again.
The popular version of the lack of Internet connection - problemnetwork board operation. This problem may be due to incorrect drivers or an outdated system. You can fix these problems yourself. The user is enough update drivers.
To do this, through the menu " Start» open « Control panel I" and in the search bar write the phrase " Device Manager". In the list, look for your network card and click " Update device drivers". Then we follow the prompts, basically agreeing with everything that the system will offer. After updating the driver, the computer should reload.
To restore the Internet, you can also swipe editing the registry. In order to fix the problem, you need to run the registry through the menu " Start". To do this, in the start we find the button Run or press the keyboard shortcut Win+R. In the window that appears, enter regedit and go to the register. 
Opening the way HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters and create the parameter " EnableRSS', assigning it the value '0'. 
You can fix the problem even easier by running the program CCleaner or TotalSystemCare and scan the system, then restart the PC.
Nevertheless, if none of these reasons eliminated the problem of the lack of the Internet, seek help from specialists.
Hello dear subscribers! There are very few days left until the new year 2017 and I decided to publish another interesting article for you. The topic of today's article will be directly related to access to the Internet. In the Windows 7 and 8 operating system, users quite often encounter an Internet connection problem, namely, with error 651.
The system does not allow you to connect with a high-speed connection. A message appears on the screen with the text "The modem or other communication device reported an error" or "Error 651 when connecting to the Internet in Windows 7". If you encounter such errors, then today's release will help you get rid of such a problem, and you will solve error 651 when connecting to the Internet once and for all.
So, in this article I will try to talk in more detail about several effective ways annoying error fixes that differ depending on the version of the operating system. Methods for deleting a message do not depend on your provider, be it an MTS modem, Rostelecom or Dom.ru. I hope that the instructions will help solve the problem without reinstalling the operating system.
The first steps to help you decide to resolve error 651 when connecting to the Internet in Windows 7
The following are simple steps, which helped me get rid of error 651. I use the version of Windows 7, but judging by the user reviews, these methods work on more modern systems– Windows 8 and 10. Follow the simple steps and try to reconnect to the network after each one:
1. Check if the USB cable to the computer, just in case, pull it out and insert it again. Check the cable itself for a break. I had a situation when my cat gnawed the cable)).
2. Reboot the router or modem - the device must be unplugged, and then restarted after 1-2 minutes.
3. Be sure to check if they work correctly themselves USB port s. To do this, you need to make sure at least that, for example, connected flash drives are successfully displayed in the operating system and do not turn off spontaneously while copying information to them. If you suddenly find that flash drives connected to the USB port are displayed in the operating system every other time, and sometimes the problem of connecting flash devices can be solved by restarting the computer, then I recommend that you read the following articles:
If the above steps did not help, let's try to re-create a high-speed PPPoE connection on the computer. This can be done with hot Windows keys: press the Win + R combinations and drive in rasphone.exe in the window that appears. After that, a simple menu will open where you will need to create a new connection and enter your username and password, if any.
And if error 651 appears already when you first create an Internet connection?
1. In this case, you need to check if the parameters you entered are correct. For example, for VPN connections users often enter the wrong VPN server address.
2. In the case when a connection is used via a wireless connection, it is worth making sure that the Wi-Fi adapter is activated on a desktop computer or laptop.
Have you installed a firewall or antivirus program before the error occurs? If so, then you should check the settings, the program may be blocking the connection. If necessary, you can completely disable the antivirus and check if the Internet works without an antivirus program.
3. Contact your ISP, there may be a breakdown or software failure hence the lack of internet connection.
I have analyzed the most simple actions that do not need to spend a lot of time, and a novice user can easily follow the steps. But if the methods of the desired result did not bring, then it is worth moving on to more serious actions.
I - Reset TCP / IP parameters
Let's start by resetting the TCP / IP protocol parameters, which is present in the operating Windows systems 7 and 8. There are several options for performing this procedure, I recommend the fastest and easiest - use a special utility called MicrosoftFixit.
It is better to download this utility from the official Microsoft website. not to run into malware, trojans, viruses/ http://support.microsoft.com/kb/299357
You do not have to do any manipulations yourself - just run the application, it will reset the connection protocol, all that is required of you is to restart your computer and try to connect to the Internet again.
I also came across information that getting rid of the annoying error 651 when connecting to the Internet in Windows 7 helps to uncheck the TCP / IPv6 protocol in the connection properties. To perform this action, you need to go to the connection list and open the properties of the high-speed connection.
To do this, we follow the following path: we go to the "Network Control Center", then move to the "Change adapter settings" section, right-click on the desired connection and go to "Properties". Here you need to go to the "Network" tab and find the TCP / IPv6 protocol in the list of components - uncheck it. Next, I suggest you go to the next step to consider error 651 when connecting.
II - Update network card drivers
Installation latest drivers for your network card can also help get rid of error 651. You need to know the name of your motherboard. You can read more detailed and detailed information from this material. This information can be obtained using special utility. There are other options - look at system unit or find a box from the motherboard.
Go to the official website of your hardware manufacturer and find the drivers responsible for the network connection there. Sometimes uninstalling solves the problem. software that you installed yourself. In this case, you must allow the system to update and install the missing Windows components.
Another important nuance is that sometimes error 651 appears due to the fact that two network cards are installed in the computer. Try disabling one of them (which is not in use).
III - Editing the Registry
First of all, this method is aimed at fixing error 651 in server versions of Windows, but for some users it also helped in a regular operating system. In general, if you have an error with the text “The modem or other communication device reported an error”, then you should try these steps:
A) Start the registry. To do this, you need to press the key combination Win + R on the keyboard and enter the regedit command in the window that appears, as shown in the screenshot below.
B) Now open the registry key called HKEY_LOCAL_MACHINE\SYSTEN\Current ControlSet\Services\Tcpip\Parameters.
C) With the right mouse button, you need to click in an empty place in the right area and in context menu select "Create a DWORD (32-bit) Value". The parameter must be named EnableRSS. It must be set to O for it to work.
D) In the same way, you need to create the DisableTaskOffload parameter, only this time the value should be 1.
E) Done, now you need to download the registry editor to restart your computer. Try to connect to the Internet again, the problem may be solved.
IV - Checking the hardware component
Quite often, the cause of such a failure is hardware. If the methods described above did not bring proper results, then before reinstalling the operating system, try one more solution to the problem:
- Completely turn off Personal Computer or a laptop along with a router or modem. The device must be removed from the network.
- After that, you need to go to the network cables - disconnect them from the modem, network card, router. Inspect them carefully for defects and damage. If everything is in order, reconnect them.
- Start the computer and wait until it starts completely.
- Now we start the modem and wait for the full load again. If a router is used on the line, start it after the modem has finished loading.
There is a possibility that after these manipulations, error 651 will disappear when connecting. However, if error 651 still appears, then in this case there is a reason to check the performance of the modem itself, but on another computer, laptop. After all, the probability of failure of the software of the device itself also takes place. But of course, do not forget about the provider, because malfunctions can occur on their side. I suggest you watch the following video:
So, dear users on this moment these are all the methods that I know of and thanks to which they helped get rid of the annoying error 651 when connecting. I sincerely hope that today's instructions will help you if you one day have to look for ways to fix error 651. If you already had to deal with this error, then I will be glad to hear your solutions in the comments that helped you overcome error 651 when connecting to the Internet in the operating system Windows 7/8/10.
Well, and I, in turn, am completing today's article and want to congratulate you on the upcoming new year 2017, I wish you, first of all, the fulfillment of all your plans, success and prosperity. See you all in the new 2017. Bye-bye everyone!
Often, when message 651 appears, users begin to hastily return to the last working system save point or reinstall the operating system. However this problem solved in less radical ways and can take only a couple of minutes. The main causes of the error and how to fix them are discussed below.
What does error 651 mean?
One of the most common problems when connecting Windows OS to global network is error 651. It means that the system cannot connect to a high-speed channel or WAN PPPoE miniport for some reason. The problem is accompanied by the message "The modem or other communication device reported an error."What causes it?
There are a lot of reasons that cause error 651, the most common of which are:- hardware component - breakage of the Internet cable, malfunction of the network card, modem, router and other equipment;
- incorrect network connection settings;
- incorrectly installed or damaged network card, router, modem drivers;
- using wireless connection disabled Wi-Fi;
- the connection is blocked by a running antivirus, firewall;
- there are problems on the side of the provider;
- malware on the computer.
What to do to fix the error?
If you encounter error 651 when connecting to a network on your computer, it is recommended that you first perform the following steps (after each of them, try to connect to the Internet):- check if it is connected securely network cable- remove it from the computer, router and reconnect;
- reboot the computer, modem, router - turn off the device, unplug the plug from the outlet and turn everything on in reverse order;
- check with your provider about possible problems with connection from his side;
- re-create a high-speed PPPoE connection (use the Win + R buttons to call the Run program, enter the rasphone command and press Enter - then follow the system prompts), reconnect;
- if the problem arose when you first created the connection, check all the data entered during the setup;
- when using PPPoE over a wireless connection, make sure that wifi adapter active;
- if the error occurs after installing a firewall or antivirus, check the program settings - sometimes protection blocks access to the network.
Checking the hardware component
Partially you have already completed this task by checking the physical connection of the internet cable. However, error 651 can also occur due to hardware problems.You can determine the source of the problem by connecting a network cable, bypassing the router (directly to the computer). If the network has appeared, with a high degree of probability, the router does not work at the hardware or software level.
If the connection is not established or the PC is already connected to the Internet directly, check the network card. Pay attention to its indicators, even if the Internet is not working, one or more of them should be on.
Reset TCP/IP settings
An option to solve the problem with error 651 is to reset the TCP / IP protocol settings. There are several methods, but the easiest and fastest would be to use the command line:
As an additional step, if the previous steps did not work, it is recommended to uncheck the TCP/IPv6 protocol in the connection properties. For this:
Reinstalling and updating drivers
Reinstalling and updating drivers is recommended when resetting TCP/IP settings does not work. Use the following instructions:
Proceed with the installation of the software that you downloaded or found on the disc. To do this, follow the following instructions:
Registry editing
The described option does not work on all user Windows systems, as it was originally intended for servers and corporate editions. If other methods do not work, use the following instructions:
What difficulties may arise?
Theoretically, error 651 can also be caused malicious code that entered the computer. Therefore, it will not be superfluous to check the PC using special tools - antiviruses. If the above actions did not work, it remains to take such cardinal steps as:- restoring the operating system through a rollback point;
- a complete reinstall of Windows.
When a computer or laptop at the most crucial moment writes that “the modem or other communication device reported an error”, most users get lost: they start calling the provider or install a spare mobile Wi-Fi on the computer.
However, this connection failure is not a serious problem, and in most cases you can fix the problem yourself. We will talk about what connection failure with error 651 means and how to fix a high-speed connection via wan miniport on windows 7 in this article.
It should be noted that error 651 does not depend on the Internet provider in any way, and subscribers of byfly, Rostelecom, Ufanet and other well-known providers equally often encounter such a problem.
Why does windows give error 651 when connecting to the internet?
This error number indicates that, for some reason, connecting a modem (or other communication device) to windows this computer performed incorrectly.
Typically, network error 651 occurs when:
- - there is no physical connection via wan miniport (the network cable is damaged, the connector is broken, the PC network card, modem or switch “burned out” due to power surges);
- - installed on windows incorrect settings network connection (due to user inattention or as a result of a system failure);
- - ongoing engineering works on the provider's side.
But in most cases given error The Internet arises as a result of incompetent user intervention in the operation of the system, respectively, and he can establish an Internet connection on his own.
How to fix connection error 651?
Understanding what it means given number errors, first of all, carry out standard diagnostics that solve most computer problems:
- - Restart your computer/laptop;
- - Turn off the power of the router or modem for 10 minutes, then carefully plug the communication device into the mains and wait until it is fully loaded;
- - Check the integrity of the network cable and the correctness of its connection to the network card connector of your PC;
- - If the computer / laptop is equipped with several network cards (Ethernet connectors) - try connecting through each of them one by one;
- - If you have another communication device (laptop, smartphone, etc.) besides this PC, or if you have several windows versions- check the Internet connection with another OS;
- - In the "Control Panel" of Windows, remove the drivers for your network card and install them latest version- from a disk, or by downloading it to the software on the official website of the manufacturer.
The network cable is working, but the modem reported error 651 - what should I do?
If there is no connection failure on other devices, then you can safely celebrate the first victory - the modem is working and your provider conscientiously supplies you with paid Internet.
- When connecting via ADSL
If the DSL link is lit steadily (respectively, the modem connection via the network cable is working properly), then in should check:
VPI / VCI parameters (which can be found in the technical support of the provider)
Bridge connection type
If the connection failed with error 651 after you ran the cable from the modem to the router and created home network wifi - the existing high-speed connection must be deleted. The reason is that the router and the modem transmit information using different protocols and often "conflict" with each other.
-At pppoe connection through a router
To fix connection failure on windows 7:
To do this, go to Control Panel > Network and Internet > Network connections”, select the section “Create a new connection or network> Internet connection> PPPoE” and in the open window enter your credentials from the agreement with the provider. Make sure you enter the parameters correctly, because connection failure often occurs due to typos in the login / password field.
Try updating raspppoe.sys - system Windows file 7 that manages PPPoE connections. You can copy the file from a nearby computer (if it does not have a communication error 651) or download from here - "http://goo.gl/oQytf2". The raspppoe.sys file is located in the "C:\Windows\System32\Drivers" folder - find it, rename it (but do not delete it - in case you have to return it to its place) and copy the downloaded file to the directory. Restart your computer and try connecting again.
If none of the methods helped you, leave a request indicating the number of the error that occurs in the service technical support your provider.
Error 651 when connecting to the Internet means that it is impossible to connect to the World Wide Web.
Moreover, it can occur on a variety of systems, not only in Windows 7. Even in Linux and similar operating systems, it is also there, only it is called a little differently.
In any case, it would be useful to understand what this error means and how to fix it.
To put it simply, error 651 means some kind of failure of the PPPoE protocol, which is used by the vast majority of providers today.
But finding the root of the problem is often very problematic. Let's analyze the most common causes of error 651.
Typically, such an error looks like this.
Reason #1. Physical connection
If it gives error 651 on a laptop or PC, the first thing to do is check your RJ45 connector, that is, the tip of the wire through which the signal passes to connect to the Internet.
Specifically, it looks like this.
To do this, it must be removed from the computer connector, inspected for any dents or other kinds of damage, and also simply blown out so that all the dust flies out of it.
It happens that even the “remove and paste” procedure itself is enough for the Internet connection to resume. The same can be done with the connector.
In addition, all visible wiring should be checked for any defects.
Often the reason for the impossibility of the signal passing can be the bends of the wire or the fact that someone put something heavy on it.
Of course, you should not climb the roof - if there are no defects on the visible part of the wire, go to the next step.
Reason number 2. Settings failure
If these methods do not help, you should pay attention to the security system that is installed on the computer.
Modem error 651 can also occur due to improper operation of the antivirus and firewall.
Reason number 3. Security systems
To eliminate this cause, you must turn off all these systems and try to reconnect to the worldwide network.
The first thing to do to try and fix the connection failure is an antivirus.
Everyone has their own antivirus, some do not have it at all (which is not reasonable), so there is no single way to disable such a program. You need to look at the user manual.
But almost any antivirus has an exit function that appears when you click on the antivirus icon in the panel quick start. This is how it looks for Kaspersky.
As for the firewall, if you have not installed any additional firewall other than the standard one that is in all Windows, then disabling it will look like this:
- Go to the "Start" menu, then select "Control Panel" (highlighted in green frame in Figure No. 7). After that, go to the "System and Security" item.
- In the window that opens, select "Windows Firewall".
- In the window that opens, in the menu located on the left side, select the item "Turn Windows Firewall on or off".
- Check the boxes next to Turn off Windows Firewall.
After that, you should restart your computer. If it doesn't help, move on to the next step.
Reason number 4. Problem with TCP/IP
If the problem is really in the TCP / IP protocol, then error 651 can also occur when connecting a router. As for how to eliminate it in this case, this is done in the following way:
- Go to microsoft.com/kb/299357 and download there special program to reset the TCP/IP protocol settings. This is done very simply.
After clicking on the link, you need to scroll (scroll the mouse wheel) the page down and find two “Download” buttons there, and if you have Windows 8.1, Windows 8, Windows RT, Windows 7, Windows Server 2012 R2, Windows Server 2012 or Windows Server 2008 R2, click on the first one.
Accordingly, if some other system - to the second. The view of this window is shown in Figure No. 11.
- After downloading, you just need to run it. The program will do everything itself. The user will have to restart the computer.
If this does not help, the only option is a problem with the network card.
Reason number 5. network card
As for the network card, the problem may occur with its drivers - they may be outdated or not work properly.
At least, this is the only problem that can be dealt with without the involvement of a specialist.
The network card may well fail completely. In any case, the drivers should be updated.
To do this, again go to the "Control Panel", there in the search bar (highlighted in red in the figure below) we write "Device Manager".
After that, we see a list of these dispatchers. We need the one next to which it says "Device Driver Update". We click on it.
After opening the dispatcher, you need to find the item " Network adapters", select your own there by its name (there may be virtual ones), right-click on it and click on the inscription "Update drivers ...".
These and other methods can be clearly seen in the video in the video below.
Error 651 Windows 8: How to Fix
Some Windows 8 users sometimes encounter an unexpected error 651. Not knowing how to solve this problem, they often reinstall the OS.
