ERROR 651: “Your modem (or other connecting device) has reported an error”

This guide will help you to understand Error 651: “Your modem (or other connecting device) has reported an error”, which you got while connecting BSNL Broadband. It will provide the expected reasons as well as solutions for Error 651.

651When using Windows 7 built-in PPPoE wizard with a modem working in bridge mode, it fails and error code 651 appears. The similar problem happens on Windows Vista or previous versions as well. For example, Error code 678 on Windows XP is equivalent to error code 651 on Windows 7. But, some times other reasons may be for error 651. Like problem may be due to problem in windows 7 files mainly with PPPoE driver file raspppoe.sys

Solution:

  1. Replace the raspppoe.sys in Windows/System32/Drivers directory. (High Risk!): The RAS PPPoE driver file “raspppoe.sys” found under c:\windows \system32\drivers folder seems to be the root cause of the problem. Fortunately, we can workaround the problem simply by renaming the original raspppoe.sys file to something like “raspppoe_orig.sys” copying a working file from a Windows Vista system. If you do not have access to a Windows Vista system. You  may  download raspppoe.sys file (unzip) from       http://www.windowsreference.com/wp-content/uploads/2009/05/raspppoe.zip
  2. Windows System Restore in back date may solve the problems.
  3. Uninstall Microsoft Virtual PC 2007, the problem seems to be fixed.
  4. Disable IPv6 for your connection source.
  5. Reinstall LAN/NIC drivers.
  6. Last but most easy solution is to change the modem configuration from Bridge to PPPoE (This procedure I will explain in Modem Configuration Topic).
