Broadband connection error 678 meaning:

When using ADSL dial-up, the local computer sends a request service to the terminal server through the network card, but Due to a problem with the network line or computer hardware, the terminal server cannot receive or return the requested data. When the local computer does not receive the return information, it will prompt the code information of error 678.

Fault Analysis:

Broadband arrears, bad oxygenation of the cable head, ADSL Modem damage, and cable breaks are often the cause of such problems!

Solution:

Case 1: Check whether ADSL Modem (common name: cat) works normally

1. At present, most Modem have panel indicators. According to the indicator light, you can judge the problem direction. First confirm Check whether the Power indicator on the panel is always on, otherwise check the power;

2. Then check if the ADSL broadband signal indicator is always on. (When the Modem is powered on, the indicator should blink continuously.) After detecting that the broadband signal is normal, stop flashing, keep it on, this process is about 1 minute). If the indicator light is still blinking after the modem is turned on for a long time, it should be checked from the external line (from the voice separation). Between the modem and the modem, this situation is mostly caused by the broadband arrears. You should call the broadband provider's service phone (for example, call the telecom customer service phone 10000) on the premise that it is not arrears;

3. Check whether the LAN or LINK indicator on the panel is always on. If the LAN indicator is always on, it indicates that the computer and Modem are directly linked. If the indicator is not lit, you should check the link cable between the modem and the computer.

4, the DATA indicator on the Modem panel flashes to indicate that the computer sends or receives data from the terminal server. When the error 678 occurs, the DATA indicator will not light up. The reason is very simple, because there is no data exchange;

Case 2: Check the local computer network card settings

After checking if the ADSL Modem status is normal, the error 678 code still appears. You should check the local network card settings.

The details are as follows: First close Modem power, right click on the network neighborhood, right click on the local link icon, select disable, then restart the computer, after the restart is complete, right click on the local link icon and select Enable.

Tips:

1. Computer hardware damage or poor contact of the cable head will also lead to the error 678 prompt, you can also try to replace a new network card, crystal head.

2, if you are using a router to access the Internet, in principle, the router should be set to automatically dial (refer to: router settings), otherwise there may be error 678 prompt message.

The above is the fault analysis and solution for the error code 678 when the Win7 system is connected to the broadband. If the friend with the same problem finds the cause of the fault according to the above method, the problem can be solved easily.
