I don t have a broadband connection. The ACT light does not come on. LAN is on, and the ADSL light k

Hello, friend, if your computer's broadband Internet display "error 651" is caused by modem damage, poor contact of network cable and network card, **line obstruction, etc., the treatment method is as follows:

1.If you have a router, power off and restart it first, if it still can't be used, please remove the router for the following operation detection;

2.Check if the modem signal light is OK:

1) If it is normal, please try to deal with it as follows: restart the network card, unplug the network cable, and restart the modem;

2) If it is not normal, please try to deal with it as follows: unplug the ** cable, restart the modem, check whether the splitter is connected correctly and unplug the above cable.

If the problem cannot be solved after the above simple troubleshooting, you can contact human customer service for processing.

The "Error 651" displayed on broadband Internet access is mainly caused by the failure to connect the user's terminal computer with the Netcom central office equipment, which is generally divided into five situations: "network cable failure", "modem failure", "network card failure", "modem itself setting", and "network operator problem". 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.

If the problem is still not solved, you can contact the local customer service for feedback.

Broadband Error 651 is generally Windows in Safe Mode, or other error.

Solution: When this error occurs, check: 1. The network cable is not connected, 2. The modem is faulty.

3. The network card is faulty.

4. The modem itself is set. By redidling again, a new specific error can be reported**.

It could be that the line interface is broken, or it could be a problem with the network.

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

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.

First power off this device and restart it once, take the router away, and connect directly to the computer from the cat to dial up the Internet to try.

If the above two methods can't be solved, then you can only call the customer service ** to report for repair, which is a network problem.

Call the operator** and let them check it, if there is no problem with the network over there, check the network card driver, because you can't connect to the Internet and don't uninstall it for the time being! Let's talk about the cat to cut off the power first, and then connect it after ten minutes to see if it can be faced!

Error 651 is an official issue with Netcom or Telecom if you don't owe money.

There are many reasons for this phenomenon, you can judge the root cause of your failure according to your own situation, and check carefully, your problem can be basically solved

1。Check whether the contact between the crystal heads of various equipment interfaces in the house is good, and whether there is rust, oxidation, grounding, loosening, etc.

2。There is no external interference source, many equipment damage is directly related to grounding, no grounding or poor grounding will lead to inter-code interference, bit error, delay, packet loss, intermittent, dropped, crash, stuck car round, automatic shutdown, repeated start, repeated start, frequent restart and other phenomena.

3。Without enough bandwidth to ensure traffic, the computer cannot be smoothed, which is related to the dealer's operating conditions and the medium used.

4。If the line is damaged and the signal is not accepted well, the system will not be able to make a correct judgment on the code element, and it will produce bit error, serious bit error is packet loss, serious packet loss is the cause of delay, and serious delay will be drop, which will produce slow, delay, repeated start, drop, delay, drop, drop, interrupt, disconnection, automatic shutdown, crash, etc.

5。Viruses can slow down the computer, freeze, drop the connection, get stuck, and start repeatedly, so it is necessary to clean up the system. Reinstall the system in a clean state (no other software is installed, except for the driver), install the firewall and Trojan scanner software.

Note: Do not surf the Internet without firewalls and Trojan scanning software.

In there is a look at the main configuration of the computer, memory, CPU, graphics card, etc., whether it has been eliminated garbage.
