Many ADSL dial-up friends have encountered a prompt code when they cannot connect to the network, so how to solve the broadband connection error 678 ? Next, let the editor tell you~
The 678 error code is one of the fault codes of broadband, which means that the remote computer does not respond, and it is also sent from the computer to send data to the network card, including the transmission of the telephone line and the port processing of the terminal board at the central office (telecommunications office computer room). If there is a problem with data transmission during the process of returning data to the computer, a 678 error will be prompted. In other words, the network is down.
In the early morning, I started to search for the solution to the 678 error code on the Internet. After searching for a long time, the Internet was full of a lot of professional knowledge. After reading it for a long time, I was stunned for a while, a small 678 error code. So troublesome, I solved it like this, and share it with you:
The appearance of error code 678 is caused by the following situations. We only need to eliminate them one by one:
1. Check whether the network cable is loose. If the network cable is not plugged in properly, it will also cause a 678 error code. Many people will ignore this small problem, but it is the reason for the proportion. Of course, you also need to check the network cable interface between the router and the router!
2. If the network cable is not loose, then we need to check the problem of the router. First, check whether the signal light on the "router" is normal? First of all, it is recommended that you restart the router. The router is sometimes tired and needs to rest!
3. After restarting the router, try to connect to the broadband again. If the 678 error code is still displayed, it is estimated that it is a problem with the broadband operator. It is recommended that you contact your broadband operator.
