Broadband connection... 651 or 691 error, how to solve it! Help

Set up a broadband connection again.

I specifically went to the telecom to ask the 651 question, unplug your wireless router, connect the network cable directly to the computer, and it's fine.

1. Right-click on the network connection in the lower right corner of the computer desktop, and click "Network and Sharing Center" in the column that appears

2. Click Local Connection on the right side of the network sharing page to enter the local connection state.

3. Click on the following properties in the status bar to enter the connection properties panel.

4. Select Internet Protocol version 4 with your mouse and click Install below.

5. Double-click the service in the installation selection bar. Check if there are any services that need to be installed, if not, click OK, if there are any, and if there are any, you want to install them. If you don't install it, you will be prompted 651Once installed, click OK below.

6. Then click "Configure Options" in the upper right corner of the properties panel

7. On the NIC properties page, find: connection speed and duplex mode, and click to select. Change the value on the right to "Auto-Detect" and click OK. You can use a broadband connection.

8. If the network card driver has a question, it will also prompt such a **, right-click the computer on the computer desktop. Click Device Manager in the field that appears.

9. Click on the network adapter below, and the network card driver will appear. Right-click on the network cable and click Uninstall.

10. After clicking OK in the pop-up panel, the NIC driver will be automatically uninstalled.

11. After uninstalling, click the operation option on the device manager, and select "Scan and detect hardware changes" in the column that appears, and the network card driver will be automatically installed. Wait patiently for the installation to complete and restart your computer.

The answer is generally due to the modem not finding the corresponding dial-up port and the error is reported, which may be caused by a problem with the operator's line or the line or network card connected to the external network at home.

First consider the network card driver problem, this problem is more common, right-click on the desktop computer - property 2On the computer properties page, select "Device Manager" to enter!

On the Device Manager page, find the "Network Adapter" under the "Network Adapter", there are generally two network cards, one wired and one wireless network card! Click the wired network card right click - disable, the prompt box appears click OK, and then right-click to start! See if redialing is OK, and if not, look down.

4 .Right-click on the wired NIC and select Uninstall to uninstall the NIC driver! 5 .Click on the operation of the device manager menu - scan for hardware changes, the system will generally re-drive the network card with a general driver, and after the installation is completed, restart the computer! It should work!

651 is for Win7 system, it corresponds to 678 of XP system, 815 of Vista system, which means: PPPoe through WAN micro portThe remote computer did not reflect the 691 mainly because there was a problem with the username and password.

I also want to know, now I can't connect. It's too painful.
