Error 651: The modem (or other connecting device) has reported an error.
If you’re getting this message then here is solution to fix this error.
Background of Error 651:
You see this error only when you try to connect/share your broadband connection with one or more devices. It works fine if you don’t try to share your broadband connection.
This error comes because of wrong configuration on your modem settings. In you modem configuration we have to enable the multiple device sharing option. This settings will be usually done by the internet service provider (ISP) with our system. If they have not done or configured your modem to share internet connection then here I will tell you the process how to configure your modem to share your broadband connection.
How to Fix Error 651 in Windows 7:
Recently I have taken BSNL (Internet service provider) Broadband connection, When I try to share the broadband connection with my Windows Xp (desktop) and Windows 7 (laptop) it started showing error. After I called the BSNL officer to configure modem to share broadband connection on other devices. Here are the two solution to fix Error 651.
Solution 1: Call your Internet service provider (in my case BSNL) to configure the modem settings to share Internet connection.
Solution 2: Fix yourself!. To fix yourself just follow the steps as show below

1. Open modem configuration Page, to do that open any browser in the address enter http://192.168.1.1/

3. In the left hand side you will see some options, click on the Configuration tab. In configuration select Internet Connection
4. The Internet connection configuration window will display like this. But in your case the last option will be bridge_0_35. You have to delete the option bridge_0_35 by clicking on the delete icon
