Here's how to deal with such cases:

1. Please replug the network cable and ** cable and restart the modem test;

2. Please disable the local connection first, and then enable the local connection;

3. Please reinstall the NIC driver;

4. If you use a router, please remove it, and dial test it on a single computer.

Error 651 is an error message in the Win7 system, which is equivalent to error 678 in the XP system**1Error 651: The remote computer does not respond, it is generally possible that the broadband modem or line has a problem that causes the broadband cat to fail to synchronize, or there is a problem with the operator's equipment room, and there may be a problem with the computer system, 2

Check the status of the broadband cat, there is a DSL or whether the link light is always on (different brands of cats have different English logos), the DSL or Link light on the broadband cat indicates the communication status between your broadband cat and the operator's computer room equipment, it should be always bright at normal times, if it is not bright or shiny, the biggest possibility is that there is a problem with your **line, it is recommended that you directly call the operator's customer service** to report the obstacle for people to check and repair, and it will generally be dealt with in one to two working days.

Error **651 is one of the phenomena of broadband Internet error** query obstacles, which is manifested by the network card light not lighting or flashing all the time.

If error **651 occurs, it is recommended that you troubleshoot the problem from the following aspects:

1. Restart the modem and plug in the optical fiber connector.

2. Judge whether the status of the modem indicator is normal, if it is abnormal (the modem lights up red, the PON light flashes, and the indicator light is abnormal), you can call the local 10086 for broadband fault reporting;

3. Remove the router and directly connect to the optical modem to dial-up to connect to the Internet, if the dial-up connection fails, you can further feedback and deal with it through the broadband fault reporting center;

4. Reconfigure the router.

Broadband error 651 is mainly caused by the connection between the user's terminal computer and the Netcom central office device. In general, it is divided into four situations: 1. The network cable is not connected 2. The modem is faulty 3. The network card is faulty 4.

Error **651 is one of the phenomena of broadband Internet error** query obstacles, which is manifested by the network card light not lighting or flashing all the time.

It is mainly caused by the connection between the user terminal computer and the Netcom central equipment, and the main situations are as follows:

1. The network cable is not connected;

2. Modem failure;

3. Network card failure;

4. The modem itself is set to the problem;

The main methods of treatment are as follows:

1. Carefully check whether the network cable is loose;

2. If there is no problem with the network cable and the error is still reported, open the "Network and Sharing Center" in the control panel.

3. Select "Change adapter settings";

4. Right-click the local connection and select "Properties".

5. Click to select the "Advanced" page in "Configuration";

6. Select "Connection Speed and Duplex Mode", set the value to "100Mbps Full Duplex", and click OK;

7. If it is still solved after operation, you can contact the operator to replace the modem dissociator.

If error **651 occurs, it is recommended that you troubleshoot the problem from the following aspects:

1. Restart the modem and plug in the optical fiber connector.

2. Judge whether the status of the modem indicator is normal, if it is abnormal (the modem lights up red, the PON light flashes, and the indicator light is abnormal), you can call the local 10086 for broadband fault reporting;

4. Reconfigure the router.

Error 651 is displayed for broadband connection, which is mainly caused by the terminal connection of the network device, and the processing steps are as follows:

Step 1: Reinsert the network cable and ** cable, and restart the modem test.

Step 2: Disable the local connection and then enable the local connection.

Step 3: Reinstall the NIC driver.

Step 4: If you are using a router, please disconnect the router and use a single computer for dial-up testing.

It's not connected to the Internet, and the wired is not connected.

It's a port problem, you can change the port first, or write it down again.

Error of unsuccessful dialing**. Equivalent to win

XP dials 678

Mistake. Let's start by looking at the modem

If the sync light flashes, it means that there is no signal on the line, please check that the line has been contacted, or restart the modem.

If the synchronization light is always on, it means that the signal is normal, check whether the network card is disabled, whether it has passed through the router and other devices, if so, of course, the dial-up cannot be passed.
