How to quickly locate network faults of ADSL Access Network Equipment

Users who use ADSL access network devices have encountered many problems, especially some network faults, which are a headache. Generally, users do not know what the problem is. The ADSL access network device has a CD or Link indicator. Normally, this indicator will soon remain on after the power is switched on. If other exceptions occur, if the indicator lights keep flashing, it means that there is a fault in the communication line.

In this case, you can test whether a signal exists in the telephone line. If the signal is not tested, it indicates that the line may be short or open, at this time, you must ask professional maintenance personnel to help you fix the line fault. If there is a signal on the telephone line and the indicator is still flashing, it means there is a problem with the port. At this time, you can check whether the necessary separator is connected when the ADSL line is in the household. Check whether the separator is connected to other devices, such as using an extension or anti-theft system. Of course, I would like to remind you that even if you can use a telephone line to answer the call, it cannot be concluded that the line is certainly not faulty, because the ADSL signal and telephone signal are not the same channel used.

Identify power supply faults

Using the Power indicator in the ADSL access network device, you can easily determine whether the Power supply is faulty. If the ADSL access network device is powered on and finds that the Power indicator is not on, it can be determined that the Power supply of the device is abnormal.

Identify hardware faults

Using the Test or Diag indicator in the ADSL access network device, you can determine whether your device has passed the self-check Test. Generally, this indicator will flash when the power of the ADSL access network device is connected. This indicates that ADSL is in the self-check status. Once the self-check task is completed, this indicator will automatically go off. If the indicator is always on, it indicates that the ADSL access network device has not passed the self-check.

Identify network faults

Using the LAN indicator in the ADSL access network device, you can easily diagnose whether the network device and connection to your computer are normal. Under normal circumstances, the indicator is always on. If the light is not always on, it indicates that the network connection may fail. The specific performance is as follows: when the CD or Link indicator is on normally, if the LAN indicator is not on, it indicates that the network connection between the ADSL access network device and the network card is faulty. At this point, you can try to replace another network card.

If the LAN indicator is always on but you cannot use ADSL for dialing, it may be a problem with the dialing software. In this case, you can delete it from the system and reinstall the dialing software correctly. If you still cannot work, you must press the reset button in the ADSL access network device to enable ADSL to work with the default network parameters. Note: When you press the reset button, you first find a circular hole about 2mm in diameter on the device and stamp it with something hard like a refill when the power is on, at the same time, you must maintain this status for more than 10 seconds before the reset is successful.
