As soon as I took the book to the store that sold it, I plugged it in and used it when I got home, but I couldn't use it when I got home.

Error 678 is a network problem, and you should call customer service.

Error 678 occurs among dial-up Internet users and is a common fault prompt encountered by broadband ADSL dial-up Internet users. 678 errors. To put it simply, the network is not working.

The following methods can be used to solve the problem:

1. First of all, confirm that the adsl modem dial-up is normal, because the IP automatically obtained by the network card is not cleared, so the network card cannot be obtained when dialing again.

After 5 seconds, right-click on the local connection to select Enable, and then turn on ADSL modem dial-up.

2. If the first step is invalid, then with ADSL modem turned off, still disable the local connection (network card), restart the computer, and then start.

Use a local connection (network card) and then turn on ADSL modem to solve the problem;

3. If the above steps cannot be solved, check whether the NIC light is on, if the NIC light is not on, refer to the dispatch knowledge base: "The NIC light is not lit or often does not light up" solution.

4. If the network card light is normal 1, 2 steps can not be solved, then lead the user to uninstall the network card driver, reinstall the network card driver, if the user XP system is installed: standard number: 9973, how to set up ADSL dial-up connection under winxp method to lead the user to create a dial-up connection, if the 98 system recommends that the user install rasppoe software or ehernet300 software connection.

5. If the above operation is invalid, contact the telecommunications department to confirm the port.

Failure of the modem is the main cause.

8.If you are an ADSL annual subscriber, if this situation occurs during use, it may be in arrears, please consult the customer service center. In some areas, China Telecom or China Unicom users, in the case of arrears, can get through, but can not access the Internet, at this time it may also be in arrears, because now the telecommunications departments in some areas are not in arrears, but stop the use of the network.

9.Some brands of modem are also prone to error 678 due to insufficient power supply.

My computer is sometimes like this, usually the remote server can't be connected, it may be the telecom server maintenance, cut off the power supply, wait for about 10 hours, naturally it's fine.

678 is the line is not connected well, you can shut down first, cut off the power, unplug all the network cables and wires, and then plug it back in, restart the computer after 10 minutes, and it's OK! This used to happen to my home computer, so give it a try

**The line contact is not good, and the line is not passable.

ADSL's lights keep flashing, right? Error 678 is a circuit problem, or the cat is broken, restart the cat 5 minutes after the start of the trial. Reseat the network cable, try to change it, uninstall the network card driver and try to reinstall it, and you can surf the Internet without flashing.

Error 678It's the remote computer that doesn't respond, check if the adsl is always on, if your adsl light flashes, it's a problem between your ** line and the computer, and the ISP provider is coming to the ISP provider, and it's not the ISP provider's problem.

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.

Error**678 is that you can't connect to the remote host, see if there is a problem with your network, if there is no problem, you need to call 10000 to ask Telecom.

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.

This situation will also occur if the voltage is insufficient, and it is good to wait for the voltage to stabilize, and a similar situation has occurred in my family.

Error 678 is a fault prompt commonly encountered by broadband ADSL dial-up Internet users, which simply means that the network is not available.

Broadband ADSL dial-up Internet access uses PPPoE protocol connection, transmits data through ** line, uses ADSL dedicated modem to realize data modulation and demodulation, the meaning of error prompt 678 is that the remote computer is not responding, which means that the computer sends instructions to the network card to send data outward, including ** line.

The port of the terminal board of the central office (telecommunications office computer room end) will prompt a problem in data transmission during the process of processing the return data to the computer.

Generally speaking, when you encounter this error 678, a large part of the reason is your broadband account problem, please check the account number and password carefully. If it is confirmed, it is likely that the account is in arrears, because the reason displayed is that the remote computer is not responding. Therefore, call ** to consult the telecom or Unicom service provider to see if it is a problem of arrears. If you are in arrears, you can pay the bill.

It could be that the cat is broken. Try another one.
