Error 651 with PPPoE connections in Windows [FIX]

When you try to share your broadband connection in windows OS you will see Error 651. The complete error message will look like

Connecting through WAN Miniport (PPPOE)…

Error 651: The modem (or other connecting device) has reported an error.

If you’re getting this message then here is the solution to fix this error.

error 651

Error 651:

 

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 the wrong configuration on your modem settings. In you modem configuration we have to enable the multiple device sharing options. This setting 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 the modem to share the broadband connection on other devices. Here are the two solutions 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 shown below

Note: Before doing this remove all existing broadband connection which you have created before by going to Control Panel\Network and Internet\Manage Wireless Networks

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

2. It will ask the username and password (in my case admin and admin). If it is something different in your case then check the manual which comes through the modem

3. In the left-hand side, you will see some options, click on the Configuration tab. In configuration select Internet Connection

 bsnl modem configuration

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

internet connection configuration bsnl

 

4. Now below that you will see Add> button, just click on the Add> button you will be taken to next page fill the page will below details

PVC Name: ppoe_0_35

VPI: 0

VCI: 35

Service Category: UBR With PCR

Peak Cell Rate: 0

 

and then click Next> button

error 651 windows 7 fix

 

5. Now you will be in Configuration Connection Type page, here you select

Protocol: PPP over Ethernet (PPPoE)

Encapsulation Type: LLC/SNAP

and click Next

error 651 windows 7

 

6. In the next page, you will be in the Configuration WAN IP Settings page, in that

select Obtain an IP address automatically

Check Enable NAT

and Add Default Route

then click Next

configure wan ip settings

 

7. Now you will be in “Configure Broadband User Name and Password” page

Service Name: dataone (you can give any name)

Broadband User Name: Enter the username which is given by ISP (mostly landline number)

Password: Enter the password given by ISP

Confirm Password: Enter the same password as entered above

Session established by:

Star Select Always On to automatically connect to the internet on windows startup (no dialing needed)

Then click Next

configure broadband user name and password

 

8. This is the last step, just click apply.

Internet(wan) configuration

 

Now open your browser on any of the PC (if you’re sharing the Internet) and start browsing. Now onwards you don’t need to manually dial to connect to the internet. It automatically connects on windows startup. I hope your search ends here for “Error 651”.

        Hi,

        This is a pretty old article and I’m not using BSNL anymore so I don’t think I can help with your question.

I recently started using ss cable internet. The net worked quite well for week or so and then error started coming like error 651,628,619
When contacted to operator he said there might be some problem in your operating system. How to go about it sir?

    ARUN KUMAR - February 6, 2015

    No idea dude… to check whether it is from your O.S or not, just try using your friends laptop and connect to your internet. If internet works on your friends laptop then re-install your O.S.

thank u for the article. looks very helpful.

but before i try to change the modem configuration
please consider the following too and advise.

1. i t was working fine for about a month. i was getting
internet on my laptop under wifi and on my desktop
thru the cable. i am still getting net fine on my lap and
i dont want to disturb it.
2. just before the net failed on my desktop i had down loaded
a video sharing programme which probably installed some
computer sharing program. i did restore but no use.
3. i reported the problem to bsnl who checked the modem at their end
and said everything is ok

regards
