What an error 651 when connecting to the Internet on Windows 8. Multiple network cards on a computer or a network card failure. Reinstalling or updating network drivers

Now when the concept a computer smoothly flows and merges into the concept the InternetThe errors broadcasting about an unsuccessful attempt to connect to the Internet are very and very unpleasant. Therefore, we postpone extra conversations and immediately move on to solving this problem.

Error 651 as a result of nonsense of the user

But still, in front of the main course, we will quickly go through the cases when the 651 error comes out only because the user is not compressed sufficiently in this matter. I want to remind you that diagnose the reason for the appearance of this error makes sense only when you connect the cable from your provider directly to the computer. Single network devices that can be on this path are telephone adapters or splitters. If the cable connects to such devices as a router or a Combo device that is capable of performing a PPPoe connection, then it makes no sense to even try to connect to the Internet, not to diagnose the reason for its appearance. In such cases, connecting to the Internet occurs on these devices and the only question that the user must take care is "how to connect a computer to this equipment". Nothing more.

Error 651 as a result of the disabled LAN

I think the first thing that you need to check when diagnosing 651 errors - make sure that the local network connection is actively. To check it yourself. Open window Network connections. To bring detailed reports with pictures on how to open this window in various operating systems a rather long and tedious occupation. Therefore, I will throw off several links to articles about the process of configuring Internet connection on various versions of Windows:

In the article about configuring Internet connection on Windows XP, we open this window. In other operating systems, you need to reach the window Network and Shared Access Control Center And click the button Change adapter parameters. Who is too lazy to do so many movements, vbo

nCPA.cpl

and the result will be the same. In addition, you can use, thanks to which the transition to this window will be carried out thanks to one blow on the mouse button. You have approximately such a window.

Item you are interested in will be name , and in the case of Windows 8 - Ehternet. As you can see on my example, connections can be a lot. We are only interested in the above item. This has three lines (if you do not have it right, right-click on an empty area and sequentially select View-tile):

Name LAN.
LAN state.
The network adapter used to connect over the local network.

At this stage, we are interested in the Item state of the LAN, that is, the second line. The second line can take several values:

Included, connected, unidentified network, limited access. Such items suggest that everything is in order and LAN is actively. This is the most unpleasant item, because it is difficult to understand what exactly not as and why when trying to connect to the Internet, the 651 error comes out. In this case, I suggest you to restart the computer, make sure the network card activity and then call the technical support of your provider. Usually in such cases the problem is either on the side of the provider, or you need to capitalize the operation of the network card and the relevant drivers.
Network cable is not connected. A very unambiguous point that says that the network card does not see the cable. Perhaps the cable is loosely connected or damaged. All this must be checked. If the cable has no damage, then you need to go to check the operation of network drivers.
Disabled. The most pleasant condition. If you see it, click on LAN connection right-click and select Enable. After that, try to connect to the Internet. It also happens that the LAN immediately after switching on Disabled. In this case, try reinstalling the drivers on the network card.

Your task at the first stage is to make sure that LAN is on and then act in terms of the situation. You can also make sure that there are no connections on the local network at all. In this case, it is necessary to move to the checkout of the availability of network adapters.

Error 651 as a result of incorrect operation of network adapters

Before the transition to this item you need to remember what is written in the third line of connection on the local network. For those who do not know, this is the name of your network adapter. The activity of this adapter we will check. To do this, you need to open the menu Start and right-click on the item Computer / My computer.In the context window that opens, select Control. In the window Computer Management You need to reveal the node Device Manager and find item Network Boards / Network Adapters. In the discontinued point, find the adapter whose name coincides with the third line of the LAN. The only thing you need to do is make sure that there is no red crossed in the artificial adapter. If it is, click on the adapter right-click and select item. Cycling. Usually a red cross on the adapter can be found when there are no connections on the local network at all. In the remaining cases, it is not necessary to hope for good luck, but still it is better to check.

In addition, I will say that if you could not find any LAN, nor any adapter, then you have either there is no network card, or drivers for this very network card are not installed. In this case, it is purely your personal problems. Call with a computer.

How to get rid of the error 651?

From the above items, you should have understood that the simplest reasons for the 651 errors when connecting to the Internet are covered with a LAN or network adapter. These problems user can solve himself. But what to do in other cases?

If a LAN connection Actively or writes that the cable is not connected, the corresponding network card is active and the cable has no damage around the apartment, then be sure to call the technical support of its provider. They will tell you what the problem is: either with your computer or somewhere on the line. Check it can be quite easy: if your computer's MAC address is visible - a problem with a computer. If not, then you need to check the line, and the computer is possible.

I hope you are not too confused in the given advice to solve this problem. I wish you good luck and less dating with a 651 error.

Error 651 may arise due to technical problems from the provider or your network equipment. This includes a computer network card, router or modem. If Windows7 is installed on your computer, then the sources of problems can be even more. After reading this article, you can achieve the desired result, that is, to connect the Internet to your computer quickly and independently.

What it is

Many people are wondering - which means a 651 error when connecting the Internet. And this means that in the system there is a failure of a kind of equipment that is responsible for the network connection, that is, it is a binding part between the network and the computer. You can be 100% sure that they did everything right, but still the signal can not get to the PC or laptop. So how to fix this problem?

The first thing to do is to call your provider and ask what's the matter. If he says that everything is fine on the line, then the problem will need to solve home independently or, in the extreme, invite a specialist who understands such situations. In this article, everything will be painted in detail, so first you need to try to cope with this task yourself.

Causes and solutions to this problem

There are two types of network equipment that binds a signal from the provider with your computer. From this you can also find out what the error is 651 when connecting the Internet.

So, 2 types of connecting network equipment:

You are responsible for the equipment that is in your private property. Correction of the error with your own hands can be in the event that the failure occurred on your equipment (this happens in 85% of cases).

If you applied for help in the Internet, then you think that it means a 651 error when connecting the Internet and how to cope with it. Let's start with a network card.

Error 651 when connecting to the Internet via router

What does the error 651 mean when connecting the Internet through the router? This means that this equipment failed. The first thing to do is to restart the router. Most likely, the problem is in his "freezing". This can occur quite often, especially if the equipment works without shutting down. The router breaks very rarely, so the reason for the long lack of the Internet is most likely in something else.

Network cable

Through the cable, the connection with the Internet can also disappear. What are the reasons for this:

Registry change

You can also solve the problem due to the registry change. It is pretty difficult procedure, but if you are not a simple PC user, you can try.

Error 651. - the most insidious of windows connection errors. It occurs - and you do not know where to dig and which side is to look for the problem. Error 651 when connected to the Internet It can mean a lot - problems with your equipment, problems with the equipment of the provider, the PPPoe protocol failure on your computer, etc. First, reboot your computer and modem - ADSL or GPON - and check the connection. After that, call back in technical service provider and ask if there are no problems on your line and are some technical work. It happens at any provider: Rostelecom, MTS, Dom.ru, Byfly. As a result, you will torment your equipment for hours, trying to remove the error 651, and the reason will be in the problem on the equipment operator equipment.
Sometimes it also happens that the cause of the error 651 is simply a malfunction of the operating system and you just need to restart the Windows operating system.

Error 651 in Windows 8 Windows 8.1 due to the interface features, it may look like this:

But the answer to the question of what to do and how to fix the connection failure with the 651 error is the same for Windows 7, and for Windows 8, and for Windows 8.1.

Correction options:

1. If you are connected via ADSL via modem.

Watch the DSL or Line indicator - he must burn continuously or be very, very quickly. If it does not burn or slowly blinks - check the modem connection, splitter and room wiring. While the DSL-Link will not - you will be constantly issued 651 connection errors, as there is no channel with a provider. Try to connect a modem directly at the entrance to the apartment (without splitter and phones) and see whether there is a link. If it does not appear - call the provider and call the Montter to check the line. If the DSL LINK is lit stable, but still Windows issues an error 651 - then we go to the modem settings and in the WAN or Internet section check whether the VPI and VCI parameters are correctly spelled out. If they are registered wrong - you will also have an error 651. You can learn your VPI / VCI parameters in the provider technical support. The second point - the connection type must be Bridge. If worth it PPPoeThe connection is carried out from the modem and then it distributes the Internet to the connected devices. Of course, when you try to connect to them - an error of connecting 651 - Miniport Wan After all, the modem in this mode will not miss the connection over its own.

2. If you are connected via FTTB (optics in the house) and you have a router and an error 651 is issued.

There is a logical question - and why do you run the connection from the computer? The meaning of the router is to connect to the provider and distribute the Internet to the connected devices.

If your provider cable is included in the router LAN-port is not correct. The provider cable must be connected to the WAN port, and the PPPoE connection is configured on the router. Therefore, we go to the router settings overload it to the router mode (PPPoE).

3. If you are connected via GPON (optics in the apartment), you have an optical terminal and there is a connection failure.

In the case of C GPON - all the same as with ADSL - you have to have an optical link, and your ONT optical terminal must be configured in Bridge mode. If it is in PPPoE or Routing mode, then you try to run high-speed connection will always be issued a 651 - Wan Miniport network error.

4. You are connected directly to the network card, or your ADSL modem or GPON terminal is configured correctly, and the Internet cannot be connected to the Internet.

In this case, try to do the following. We remove the high-speed connection - the so-called "dialer" - and create it again.

Here are the instructions and. Very often this problem can be defeated in this way.

5. Error 651 occurs due to antivirus, firewall or firewall.

It happens that because of any suspicious network activity or due to improper network setting in the firewall or firewall rules, network activity via a specific adapter or connection is blocked and, accordingly, it gives the MINIPORT WAN error. To exclude this option, you need to deactivate the computer security system for a short time and check the connection. You need to start with the simplest -. If you have a third-party anti-virus system with a built-in firewall - it is also necessary to try to disable it. How it's done?! Any antivirus program has its own icon in the system tray, on the right, at around the clock. We find it there and click the left mouse button. Select the item to disable, suspend, output or something in this spirit. For example, here's how to disable DrWeb antivirus:

The screenshot shows how to stop antivirus protection. To stop also Firewall - Select the appropriate value in the menu and disconnect it. And here how to turn off the caspersion antivirus Or and Kaspersky Internet Security:

6. Network card failure.

There are cases that because of some failure or error starts to "port" a network board or its driver. You need to try to reinstall the network fee. To do this, you need to press the combination of the Win + R keys - the "Run" window opens. In it we write a team devmgmt.msc. and press the OK button. Windows Device Manager will open:

We find the section Network feeswhere the network card controller is located - the most common is REALTEK, NVIDIA, ATHEROS, Intel or Via. Click on it right-click and select item Delete. After that reboot the computer. Windows will re-identify and put the network card drivers, but just in case, the disk or archive with the driver should always be at hand.

7. Problems with a modem or optical terminal.

Yes, a failure in the work happens on different modem models and terminals - both cheap and expensive. Start buggy modem may due to different reasons: firmware curve, unstable power supply, channel errors, etc. This is a normal practice. To exclude this option - you need to reset the settings of the modem button Reset.which is located on the rear panel of the device:

Before resetting the settings - go to the web interface, find the Internet section and save the data to connect to the provider and authorization. Otherwise, you may encounter the fact that after resetting the settings - do not know how to configure the modem.
After that, on the enabled modem, clamp the button Reset. And we are waiting for 7-8 minutes. The modem must blunt diodes on the muzzle and will reboot.
In case you have a GPON ONT-terminal - call the provider and inform suspicion of failure in the work of the terminal. Usually optical terminals are configured by the operator remotely. The settings of your device will be checked and reported.

P.S. Finally, I want to note that on the Internet on some sites they are advised to climb into the registry and add "Enablerss" or "Disabletaskoffload" type parameters. So it helps it only on Windows Server 2003 and that, only when an error occurs 651 on PPTP or L2TP connections. On Windows 7 and Windows 8 it is useless to do it!

Hello, dear subscribers! Until the new 2017, there were quite a few days left and I decided to publish another interesting selection for you. The topic of today's article will directly be associated with access to the Internet. In the Windows 7 and 8 operating system, users are often faced with the problem of connecting to the Internet, namely, with a 651 error.

The system does not allow you to connect with high-speed connections. A message appears on the screen with the text "modem or another communication device informed about the error" or "Error 651 when connecting to the Internet in Windows 7". If you encounter such errors, today the release will help you get rid of such a problem, and you once and forever solve the error 651 when connecting to the Internet.

So, in this material I will try to tell more in detail about several effective ways to correct the annoying error, which differ depending on the version of the operating system. Message removal methods do not depend on your provider, be it modem MTS, Rostelecom or Dom.ru. I hope that the instructions will help solve the problem without reinstalling the operating system.

The first steps that will help solve eliminate the error 651 when connecting to the Internet in Windows 7

Below are simple actions that helped me get rid of the error 651. I use the version of Windows 7, but judging by user reviews, these methods work on more modern systems - Windows 8 and 10. Make simple actions and try to reinstall to the network after each of each They:

1. Check if the USB cable is connected to a computer, just in case, pull it out and insert it again. Check the cable itself on the absence of rupture. I had a situation when the cable was overseas)).

2. Restart the router or modem - the device must be turned off from the outlet, and then run after 1-2 minutes.

3. Be sure to check if the USB ports are correctly operating. To do this, make sure that for example, the connected flash drives are successfully displayed in the operating system and are not turned off spontaneously during the copying of information on them. If you suddenly found that flash drives connected to USB port are displayed in the operating system once, and sometimes the problem of connecting flash devices can be solved by rebooting the computer, then I recommend you to read the following articles:

If the above-mentioned actions did not help, try to re-create a high-speed RPRO connection on your computer. You can do this with the help of a Windows hot key: Press the Win + R combination and in the window that appears, drive Rasphone.exe. After that, a simple menu will open where you need to create a new connection and enter the username and password if they are.

And if the error 651 appears already when you first create an internet connection?

1. In this case, you need to check the correctness of the parameters that you entered. For example, to connect VPN users often enter the wrong VPN server address.

2. In the case when connecting via a wireless connection is used, you should make sure that the Wi-Fi adapter is activated on a stationary computer or laptop.

Did you install a firewall or antivirus program before the error occurs? If so, it is worth checking the settings, the program may block the connection. If necessary, you can completely disable the antivirus and make sure whether the Internet works without an antivirus program.

3. Contact your provider, perhaps on its side there was a breakdown or software crash, from here and the lack of an Internet connection.

I disassemble the most simple actions to which you do not need to spend a lot of time, and the beginning user can easily perform steps. But if the methods of the desired result did not bring, then it is worth moving towards more serious actions.

I - reset TCP / IP parameters

We begin to reset the TCP / IP protocol parameters, which is present in Windows 7 and 8 operating systems. There are several options for performing this procedure, I recommend the fastest and simple - use a special utility called MicrosoftFixit.

Download this utility is better from the official site Microsoft. In order not to run into malicious programs, Trojans, viruses / http://support.microsoft.com/kb/299357

You do not have to independently make any manipulations - just run the application, it will reset the connection protocol, all that is required from you is to restart the computer and try to connect to the Internet.

I also got information that getting rid of an annoying error 651 when connecting to the Internet in Windows 7 helps removing the mark from the TCP / IPv6 protocol in the connection properties. To perform this action, you need to log in and open the high-speed connection properties.

To do this, we go on the following path: go to the "Network Management Center", then move to the "Changing Adapter Settings" section, by clicking the right mouse button on the desired connection and go to the "Properties". Here you need to go to the "Network" tab and in the list of components to find the protocol / IPv6 - remove the tick. Next, I suggest you proceed to the next step. Consideration of the error 651 when connected.

II - update the network card drivers

Setting the latest drivers for your network card can also help get rid of the 651 error. You need to know what your motherboard is called. More detailed and detailed information you can read from this material. This information can be obtained using a special utility. There are other options - look into the system unit or find a box from the motherboard.

Go to the official website of the manufacturer of your iron and find the drivers that are responsible for the network connection. Sometimes to solve the problem helps the removal of the software you installed yourself. In this case, it is necessary to allow the system to update and install the missing components of Windows.

Another important nuance is that sometimes the error 651 appears due to the fact that two network cards are installed on the computer. Try turning off one of them (which is not used).

III - edit the registry

First of all, this method is aimed at correcting the 651 error in Windows server versions, but it helped some users in an ordinary operating system. In general, if you have an error with the text "Modem or other communication device reported error", then you should try these actions:

A) Run the registry. To do this, you need to press the Win + R keys combination on the keyboard and enter the REGEDIT command in the window that appears, as shown in the screenshot below.

B) Now open the registry partition called HKEY_LOCAL_MACHINE \\ SYSTEN \\ CURRENT CONTROLSET \\ SERVICES \\ TCPIP \\ PARAMETRS.

C) right-click in an empty place of the right area and select the "Create DWORD parameter (32 bits)" in the context menu. The parameter must be called EnaBlerss. So that he worked, it should be put in value of O.

D) By the same scheme, you need to create the DisableTaskoffLoad parameter, only this time the value should be 1.

E) ready, now the registry editor must be downloaded to restart the computer. Try to connect to the Internet again, perhaps the problem will be solved.

IV - check the hardware component

Quite often, the cause of such a failure is "iron". If the methods described above have not brought due results, before reinstalling the operating system, try another solution to the problem:

- Fully turn off the personal computer or laptop along with the router or modem. The device must be pulled out of the network.

- After that, you need to go to the network cables - turn them off from the modem, a network card, router. Carefully inspect them for defects and damage. If everything is in order, connect them again.

- Run the computer and wait until it starts.

- Now launch the modem and wait for the full download again. If a router is used on the line, run it after the final mode of loading.

There is a possibility that after these manipulations, the error 651 will disappear when connected. However, if the 651 error still appears, then in this case there is a reason to check the performance of the modem itself, but already 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 may arise on their side. Next, I propose to look the following video:

So, dear users at the moment are all the methods that I know and thanks to which they helped get rid of annoying errors 651 when connected. I sincerely hope that today's instructions will help you to help if you once have to look for ways to eliminate 651 errors. If you have already had to fight this error, then I will be happy to hear in the comments your solutions that helped you overcome the error 651 when connected to the Internet in the Windows 7/8/10 operating system.

Well, I, in turn, finish today's article and I want to congratulate you on the upcoming New Year 2017, I wish you, first of all, the performance of everything conceived, success and well-being. All before the meeting in the new 2017. So far, so far!
