How to solve broadband 678 error under WinXP system

When using broadband ADSL dial-up Internet access, I believe that many users have encountered various error code prompts, which may cause dial-up Internet access. Recently, users have encountered broadband 678 error code prompts under Windows XP system. I don’t know how to solve it for a while. What causes error 678 to appear? Let us follow the steps of the master.

Error 678 Introduction

Error 678 is a fault message frequently encountered by broadband adsl dial-up users. Simply put, the network is unreasonable. Broadband adsl dial-up connection using pppoe protocol, data transmission through the telephone line, using adsl dedicated modem to achieve data modulation and demodulation, the error prompt 678 means that the remote computer is not responding, meaning to send instructions from the computer to the network card to send data Including the transmission of the telephone line, the port processing of the terminal board of the central office (the terminal of the telecommunications office) to the data transmission in the process of returning data to the computer will prompt.

The cause of error 678

In general, there are many reasons for error 678 error, from the DSLAM (including DSLAM) as long as a link error, there may be error 678, such as :DSLAM equipment problems, equipment room board problems, transfer box below, trunk cable problems, wiring cable problems, user line problems, user MODEM problems, user computer network card problems, user computer system problems, etc., may lead to errors 678. The specific reasons for this kind of failure are not well judged, but after analysis, most of the cases can still be solved smoothly.

Solution

1. Have you ever moved your computer recently? Especially the ADSL Modem connection, the line has not moved? Please check first & nbsp; cat & rdquo; on the signal light is not flashing (cats are different, the indicators are also different, mainly dsl, adsl, line, link, @, etc. are broadband signal indicators), if you want to flash, check the line has There is no connection (mainly on the separator, there are three ports, each port corresponds to a line, the connection is the bus is the incoming line to the line port, the phone is connected to the phone port, and the modem or adsl is connected to the broadband cat, you can also Directly connect the telephone line to the cat to try, so that the separator can be eliminated. If the pair is still flashing, check if the telephone line has a connector. If the line is not well contacted, the signal will not be fixed (the telephone line enters the cat). If there is a problem with the crystal head or the line, it will cause the line to be unreachable.)

2. Confirm that the adsl modem dials normally, because the IP address automatically obtained by the network card is not cleared, so the network card cannot obtain a new IP address when dialing again. Will prompt 678, the operation method is: close the adsl modem, enter the control panel network connection, right click on the local connection to select disable, after 5 seconds, right click on the local connection to select enable, then open the adsl modem dial; < Br>

3, if the first step is invalid, then in the case of closing the adsl modem, still disable the local connection (network card), restart the computer, then enable the local connection (network card), then open the adsl modem can be resolved; Br>

4. If the above steps cannot be solved, check whether the NIC light is on. If the NIC light is off, check the NIC and network cable.

5, if the network card light is normal 1, 2 steps can not be solved, then uninstall the network card driver, reinstall the network card driver.

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

7, there is a situation, if you have more than two computers in your home, the HUB port used to pick up the computer is damaged, there will also be "678 error", then change a good The port is fine.

8, some of the network after the telecommunications detection is normal, there are also errors "ldquo; 678" rd, when you want to consider the use of various applications in the process of conflict, it will also cause network failure. Such as "Yahoo small assistant", anti-virus software or firewall, etc. caused an error caused by the error "678" rd. So, when you find the error "#678", you can try to temporarily uninstall "Yahoo Little Helper", quit the anti-virus software or temporarily turn off the firewall, re-connect, try to solve the problem.

9. When you have to, you can use the method of restarting "cat" and computer to solve it and see if it works.

The last method: call to find the operator's phone

Telecom: 10000

Unicom: 10010

Mobile (Tietong): 10086
