Connection failed with error 651 windows 8. Disable Receive Side Scaling and Offloading support

Error 651 usually occurs when connecting to the Internet via 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 via PPPoE protocol.

Let's take a look at some of the reasons that error 651 might appear.

Checking the cables

First, you need to check all network cables, connections and power to all network devices: modem, router, Wi-Fi adapters. Make sure that the cables are not broken, all devices are connected to the network. To eliminate the lack of contact, disconnect the network cables from the network card of the computer, router, modem and plug them back. If you are using PPPoE via wireless connection, make sure you have enabled Wi-Fi adapter on a laptop or computer.

Create a high-speed connection

You can also try to resolve error 651 by deleting and creating a new high-speed PPPoE connection. To do this, in the tray, click right click mouse over the network icon and go to.

Then go to the tab, there we select the high-speed connection on which the 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".

Selecting an item "Internet connection" and click "Next".

In the next window, click on the item "High Speed (with PPPoE)".

Introduce "Username" and "Password" and click "Connect".

Removing the 651 error can also be helped by unchecking the TCP / IPv6 protocol. To do this, go "Network and Sharing Center" – "Change adapter settings"... Then right-click on your 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 network cards

But they will definitely not solve the problems that have arisen with your home network, or teach you how to configure network devices.

Registry editor

Another way that can help resolve the error 651 problem is to change the TCP / IP settings in the Registry Editor. To do this, in the search bar of the "Start" menu, write "regedit" and press "Enter".

A registry window opens. In it, go to the following branches: HKEY_LOCAL_MACHINE / SYSTEM / CurrentControlSet / services / Tcpip / Parameters.

Then right-click on an empty space and select the "DWORD (32-bit)" parameter from the context menu.

Name the parameter "EnableRSS" and set its value to "0".

Likewise, create a parameter called "DisableTaskOffload" and set it 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 ways will help you solve the problem due to which the error 651 occurs when connecting to the Internet.
