Contact customer service, it should be that the remote computer is unresponsive.

1 modem signal light is always on (refers to the external line signal light, adsl modem brand is different, the name of the signal light is also different, common signal light.

There are: CD, DSL, ADSL, LINK, LINE, etc.).

a.If you are using a router or switch, it is recommended to connect the network cable to a computer and use the broadband connection to check whether the account can log in.

b.Check whether the local connection is normal. (If a red cross appears in the local connection, it is a modem fault, and the network cable is in poor contact or cannot be connected.

Card failure) cUnplug the network cable and restart the modem device.

2 modem signal light flashing or not on (refers to the external line signal light, ADSL modem brand is different, the name of the signal light is also different, common.)

Signal lights are: CD, DSL, ADSL, LINK, LINE, etc

a.Restart the ADSL modem device and plug and unplug the cables connected to the modem device.

b.Check whether the voice splitter is connected correctly and replug the cable (the voice splitter is connected to the main line, ** and the extension is connected to the phone, and the modem device is connected to the modem port).

What is the broadband connection error 678.

Reseat all the wires on the cat, and make sure that the cat and the ** line are fine, and then connect, don't worry, it's generally good after ten minutes, and if you don't believe it, call 10000.

There is a problem with the line, but it could also be a problem with the connecting line. You can try a different wire first.

The error **678 displayed when logging in to a mobile broadband user is usually caused by a line problem, and 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 10086 to report the fault;

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 10086 broadband fault reporting center;

4. Try to reconfigure the router.

A1. Check whether the account and password of the broadband connection are correct. Some computers use routers to access the Internet without setting up automatic dialing, need to manually connect to the network, or accidentally enter the wrong account and password when connecting to broadband for the first time. Reconnecting after timely correction can generally resolve the issue of error 678.

2. If the broadband is in arrears, the terminal server will not be able to receive or return the request data, and the local computer will not receive the return message, and error 678 will be displayed. At this time, it is necessary to pay the network fee in time, and the problem will be solved.

3. Problems with the modem (referred to as "cats") are the most common causes of error 678. First check whether the power power indicator on the cat panel is always on, otherwise check the power supply. Then check whether the ADSL broadband signal indicator (link) is always on, under normal circumstances, when the cat is connected to the power and network, the indicator will change from flashing to solid in 1 minute.

If it keeps flashing, there is a problem with the network connection.

4. Check the network cable connector, sometimes the network cable connector will be in poor contact due to oxidation, resulting in the network being good and bad, and it is very unstable. At this time, it is necessary to replace the new and *** network cable in time.

5. After checking, if the modem ("cat") signal lights are normal, the network cable connection is normal, but there is still error 678**, you should focus on checking the local network card settings. The XP system first turns off the modem power, right-clicks on the online neighbor, right-clicks the local connection icon, and selects Disable; Vista, Win7 system open the network and sharing center, click to change adapter settings, right-click the local connection, and select Disable. After that, restart the computer, after the restart, right-click the local connection icon according to the above steps, and select Enable.

6. Check the local connection. If there are multiple network connections in the computer at the same time, such as "local connection", "wireless network connection", CMCC connection, etc., and the network connection connected to the broadband modem is disabled, error 678 will also be displayed when performing broadband dial-up. Therefore, when error 678 occurs, it is necessary to check whether the local connection is disabled, if so, enable the local connection, and prompt that the local connection is connected, and then try to connect with broadband dial-up.

Note that each operating system is different when viewing the network connection, and the XP system can be viewed by right-clicking the mouse on the computer desktop and selecting "Properties". Vista and Win7 systems are viewed in the Network and Sharing Center.

Symptom: Unable to connect to the Internet, webpage cannot be opened.

Meaning of Broadband Connection Error 678: When using ADSL dial-up, the local computer sends a request service to the terminal server through the network card, but due to problems with the network line or computer hardware, the terminal server cannot receive or return the request data, and when the local computer cannot receive the return information, the ** message of error 678 will be prompted.

Personal summary: Broadband arrears, poor oxidation contact of the network cable crystal head, ADSL modem damage, and network cable fracture are often the causes of such problems!

The first thing to do is to ask the operator's customer service if there is a fault in the external line, repair, broadband arrears and other faults.

Workaround for Broadband Connection Error 678:

Check if the adsl modem (commonly known as: cat) is working properly.

1.At present, most modems have panel indicators, according to the indicator light, you can judge the direction of the problem, first confirm whether the power power indicator on the panel is always on, otherwise check the power supply.

3.Check whether the LAN or Link indicator on the panel is always on, if the LAN indicator is always on, it means that the computer is directly connected to the modem normally, if the indicator is not on, you should check the network cable between the modem and the computer.

The flashing data indicator on the panel indicates that the computer is sending or receiving data from the terminal server, and usually when error 678 appears, the data indicator often does not light up, for the simple reason that there is no data exchange.

Check the local computer NIC settings.

After checking, if the adsl modem status is displayed normally, and error 678** still appears, you should focus on checking the local network card settings, first turn off the modem power, right-click the online neighbor, right-click the local link icon, select Disable, and then restart the computer, after the restart, right-click the local link icon according to the above steps, and then select Enable.

What is the broadband connection error 678.

Broadband connection shows error 678, which means that when using ADSL dial-up, the local computer sends a request service to the terminal server through the network card, but due to problems with the network line or computer hardware, the terminal server cannot receive or return the request data, and when the local computer cannot receive the return information, it will prompt the ** message of error 678. The reason for this situation is generally that the broadband account is wrong or the login password is wrong. Broadband arrears; There is a problem with the modem ("cat") for short; The local connection is incorrect; Poor contact of network cable connectors due to oxidation, etc.

If your broadband Internet display "error 678", it is due to modem damage, network cable, network card poor contact, **line obstruction and other reasons, if there is a router, it is recommended that you can first power off and restart, if it is still not available, it is recommended that you remove the router and check whether the modem signal light is normal:

1. If it is normal, please try to restart the network card, unplug the network cable, and restart the modem;

2. If it is not normal, please try to unplug the ** cable, restart the modem, check whether the separator is connected correctly and unplug the above cable.

One. There was an error in the name on the domain (the username or password was entered incorrectly). Two.

The server does not respond (the user port in the computer room is wrong, or the account is not activated or the account is locked). Three. ** or due to overdue broadband payments.

Four. If the username or password is entered incorrectly, re-enter it and connect again.

The above four faults are the direct causes of broadband network failure.

You can call ** to consult your broadband operator and ask them to help you solve the problem.

However, the broadband connection is not connected and the error **: 678And the cat that adsl link light does not flash**678 is the remote computer does not respond, you can only find a broadband service provider to solve it for you. Telecommunications problems are common.

1.Wrong account or password (usually not).

2.Call ** to Telecom, they will test your modem data (you have to turn on the computer), if it can't be measured, it proves that there is a problem with the line or the modem is broken, you can call the telecom to repair the line or go to the telecom to replace the modem.

3.Create a network connection 2 in the online neighborhood, and network connection 3 to see if it can connect to 4If the network card is damaged, try it with a network card that is sure it is okay.

5.If the port is damaged, call Telecom to replace the port and try.

6.If none of the previous ones are true, then there should be a problem with the computer, and you can borrow a laptop to try. Personally, I think it is possible to reinstall the system or overhaul the motherboard.

I can't connect to the server on the operator's side, call ** and call him to come to repair it, I can't fix it myself.
