In some situations, manually unchecking the TCP / IPv6 network protocol, which is located in the PPPoE properties, quickly helps to remove error 651 in some situations. For implementation this action you need to go to the list of required connections and open the available properties of a high-speed connection (The sequence of actions is as follows: Network Control Center and public access- change adapter parameters - right click on the connection - properties). Next, on the Network tab, you need to disable the checkbox from the Internet protocol of the required version 6.
Update existing network card drivers
Updating drivers on a working computer network card can also be a way out of an existing connection difficulty. You just need to download them from the official website of the manufacturers. motherboard or from a laptop and follow the simple steps to install it.If you have two working network cards, then this can also cause error 651, then you should disable the one that is practically not used.
Changing the parameters of the protocol operation of TCP / IP in the network registry editor
A similar method is mainly convenient for use in server versions of Windows; I did not use it myself for user versions. It consists in changing some parameters in the registry editor, to launch which you need to use the following functional combination "Win + R" and enter regedit yourself. Next, you need to open the following section of the network registry (folders on the left) HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters using a single right-click on an empty area of the parameter list, you need to select the desired item " Create DWORD Value (32 bits)».
Set the name for the parameter as EnableRSS and set it to 0.
Create the required parameter in the same way DisableTaskOffload with the required value 1.
After that, the computer must be restarted and try to connect again.
Checking the technical hardware component
If none of the above has fixed the problem, then it is worth moving on to more radical troubleshooting methods in the form of reinstalling Windows.- First you need to disconnect your computer, router or modem.

Error 651 usually occurs when connecting to the Internet through a WAN miniport (PPPoE) in operating rooms. Windows systems 7 and 8. Its counterpart in the Windows XP operating system was error 678, and in Windows Vista – 815.
In any case, no matter how the error is called, its essence is the same - a connection error when starting a high-speed connection on Windows 7 and 8 to connect a computer to the Internet using the PPPoE protocol.
Let's look at a few reasons why error 651 may occur.
Checking cables
First you need to check everything network cables, connections and power to all network devices: modem, router, Wi-Fi adapters. See that the cables are not broken, all devices are connected to the network. To exclude the absence of contact, disconnect the network cables from the computer's network card, router, modem and connect them back. If you are using PPPoE via wireless connection, make sure you have it enabled wifi adapter on a laptop or computer.
Create a high-speed connection
You can also try to fix error 651 by deleting and creating a new high-speed PPPoE connection. To do this, right-click on the network icon in the tray and go to .
Next, go to the tab, there we select the high-speed connection on which error 651 occurs, right-click on it and click "Delete".
To create a new connection in "Network Control Center..." follow the link "Setting up a new connection or network".
Choose an item "Internet connection" and click "Next".
In the next window, click on "High Speed (with PPPoE)".
Enter "Username" and "Password" and click "Connect".
Unchecking the TCP / IPv6 protocol can also help to remove error 651. To do this, go "Network and Sharing Center" – "Change adapter settings". Then right-click on the high-speed connection and go to "Properties". Go to the "Network" tab and uncheck the box "Internet Protocol Version 6", click OK .
If error 651 still appears, move on.
Multiple NICs
If you have two network cards, then this can also cause error 651. For example, you have a home connected to the second network card. the local network or a cable from another provider. Try disabling the second network card, or the one that is not being used.
Connection blocking
The cause of error 651 can also be an antivirus or Windows firewall. They may simply block the PPPoE connection. Disable the security system for a while.
Right-click on the antivirus icon in the tray and select the item "Managing Avast Screens", then select any value. If you have another antivirus installed, look for a similar function in it.
To disable the firewall in Windows 7, read the following article.
Setting up your modem or router
If you have a modem, router or router installed, then you need to check its settings. In order to enter the router settings, in address bar browser, enter http://192.168.1.1 or http://192.168.0.1, depending on the manufacturer. Next, a window for entering a username and password will appear. We fill in these fields, by default you need to enter admin in each field. Next, we look to see if the username and password match, the type of connection and the method of connecting to the Internet. It is better to reset all settings to factory settings, and configure the equipment in accordance with the recommendations of the provider. Then reboot your device.
Also check that, say, on the router, all the necessary indicators are lit. Which flashing green light is responsible for what, you can read in the instructions for the device.
Problems on the provider's side
Internet connection problems can also be from the provider. Call tech support and ask them to check the line. Perhaps they will give some more useful recommendations. But solve problems that have arisen with your home network, or teach you how to set up network devices they definitely won't.
Registry Editor
Another way that can help solve the problem with error 651 is to change the TCP / IP settings in the registry editor. For this in search line Type "regedit" in the "Start" menu and press "Enter".
The registry window opens. We go through the following branches: HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/services/Tcpip/Parameters.
Then right-click on an empty space and select from context menu parameter "DWORD (32 bits)".
We name the parameter "EnableRSS" and set its value to "0".
In the same way, we create a parameter called "DisableTaskOffload" and set its value to "1". Look, maybe such a parameter is already there, then just change the value to "1".
Close Registry Editor and restart your computer.
Perhaps one of the methods will help you solve the problem that causes error 651 when connecting to the Internet.

Through the cable connection with the Internet can also be lost. What are the reasons for this:
Registry change
You can also solve the problem by modifying the registry. This is a rather complicated procedure, but if you are not a simple PC user, you can try.
Every day, many users connect to the global network using a high-speed connection based on the PPPoE protocol. When accessing the network, a malfunction may occur: "error 651: The modem or other communication device reported an error". The material below will analyze all the nuances that lead to the problem, and methods for getting rid of such an unpleasant problem in Windows 7.
Often, when this failure occurs, users try to reinstall Windows. But this operation, basically, does not give a result, since the cause of the malfunction is related to the problematic network equipment. Moreover, problems can be both with the subscriber and on the side of the service provider for accessing the Internet. Let's take a look at the reasons why "Errors 651" and options for their solution.
Cause 1: Malfunction in the RASPPPoE client
IN Windows services 7 associated with access to the network, there are frequent cases of the appearance of "glitches". Based on this fact, the first step is to uninstall the previous connection and make a new one.
- Let's go to . Moving along the path:
Control Panel\All Control Panel Items\Network and Sharing Center
- Remove connection from "error 651".
To create another connection, click on the object "Setting up a new connection or network"
- In the list "Select connection option" click on the caption "Internet connection" and click "Further".
- Choose an item "High-speed (with PPPoE) Connection via DSL or cable requiring username and password".
- We collect information that is provided by your provider. Set a name for the new connection and click "To plug".
- Right click on the shortcut "Current Connections". Making the transition to "Network and Sharing Center".
- Let's go to the section "Change adapter settings", which is located on the left.
- We press RMB on the connection we are interested in and go to "Properties".
- in the window "Local Area Connection - Properties" deselect an element "Internet Protocol Version 6 (TCP/IPv6)", press "OK".
- Turn off the PC and all devices that are connected to it;
- We check all connectors and cables for mechanical damage;
- Turn on the PC and wait for the full download;
- We turn on the network output devices, waiting for their final launch.
If an "error 651" occurs on the created connection, then the cause is not a malfunction of the RASPPPOE client.
Reason 2: Wrong TCP/IP settings
It is possible that the TCP/IP protocol stack has failed. Update its parameters using the utility Microsoft Fix It.
In certain cases, removing the TCPI / IP (version six) parameter in the PPPoE connection properties can help neutralize the "error 651".
You can also change the TCP/IP settings using the database editor. This method, according to the idea, is used for the server version of Windows 7, but, as practice shows, it is also suitable for the user version of Windows 7.
Reason 3: Network card drivers
BY network board may be outdated or out of order, try reinstalling or updating it. How to do this is described in the lesson, the link to which is presented below.
The origin of the malfunction may be hidden in the presence of two network cards. If this is your case, then turn off the unused board in "Device Manager".
Reason 4: Hardware
We will check the equipment for serviceability:
Checking availability "errors 651".
Reason 5: Provider
There is such a possibility that the malfunction comes from the service provider. You need to contact the provider and leave a request to check your connection. It will check the line and port for a response signal.
If performing the operations suggested above did not save you from "errors 651", then you should reinstall Windows 7.
