Windows 7 Error 651

There is a well-known bug in Windows 7 that is the cause of the 651 error code. It seems that when you try to connect using PPPoE connections in Windows 7 you may be greeted with an error code that reads: Error 651: The modem has reported an error. If you are not using a modem to connect, the error code may report some other connecting device as the cause of the error.

Before you attempt to fix the error, it is helpful to know what the terms stand for. PPPoE stands for Point to Point Protocol over Ethernet, which is a method of transporting traffic over an Ethernet connection to the Internet using broadband. RAS, or Reliability, Availability and Serviceability, is a characteristic of mainframe computers. RASPPPoE is the method that Windows uses to establish connections over Ethernet adapters. An internal issue with the RASPPPoE is the reason for the connection errors.

Interestingly enough, these same connections would not bring up an error message in Windows XP or Vista. This bug in Windows 7 has been identified and, while it is being worked out, there are a few solutions that can resolve this problem. The root of the issue with connectivity in Windows 7 seems to be a problem with the version of the RASPPPoE driver file that is specific to Windows 7.

The first thing to do when faced with this type or error is to disconnect and reconnect to the Internet. After disconnecting and reconnecting, you should restart your computer. You can also try resetting your modem and / or router, by unplugging them; leaving for at least 15 – 30 seconds and then plugging them back in. If neither of these options helps, then you may have to rename the RASPPPoE driver.

You can rename the RASPPPoE driver file by going to Computer > C > Windows > System32 > drivers. In this folder, you will find the raspppoe.sys file. By right-clicking on the file name, you can rename the file to something different like raspppoe_orig.sys. After completing these steps, attempt to connect.

Windows Vista does not have the same bug as Windows 7, so as a last resort you can download the Windows Vista driver file and replace the old driver with the Vista file. It is possible to download the Windows Vista raspppoe.sys file from the Internet. Once you have downloaded the Vista file, save it to C > Windows > System32 > drivers. After saving the new file to the C drive, attempt to reconnect.

If for some reason you are still not able to connect, you should notify your Internet Service Provider or Windows 7 support for assistance.
