Broadband failure. 1. Fault judgment method.
On the premise that the user's home can access the Internet, follow the steps below to determine the fault:
1.Check the signal lights of the modem, including power, DSL, voice (**lan). First of all, it is necessary to confirm that the ** line is normal, after the modem is powered on, the power lamp P8 should be on, if it is not on, check whether the power supply is plugged in; The DSL light is a synchronous light, which is only on when surfing the Internet, if the light will flash or not light up when you can't get out or can't get through; Usually the LAN light is on to indicate that your computer is connected to the modem normally; The voice light is used to check whether the ** line is normal, if this light is not on, you can contact the telecommunications bureau and ask them to check the ** line.
2.Check whether the network card light (Link or Ethernet) of the computer is on normally, if not, check whether the network cable is plugged in or whether there is a problem with the network card.
3.If the computer can't access the Internet, first check whether there is a problem with its network card, and if there is a demodulator, you should check whether there is a problem with the demodulator.
4.If you have more than two computers at home, check whether other computers can access the Internet, if other computers cannot access the Internet, it may be that there is a problem with the settings of the main server or the line, or there may be a problem with the Internet service in the community. If another computer has access to the Internet, there may be a problem with the local computer.
2. General faults and solutions.
In the case of confirming that there is no power outage in the area and that it is not due to line repairs, the Internet connection failure can be resolved by following these steps:
1.Confirm that the DSL and LAN lights are on, and if the DSL lights are not on, restart the modem. If it can't be repaired, check the ** line.
2.If the fault cannot be repaired after restarting, close all the windows that are using the dial-up software and the Internet Explorer window and re-dial. If error 691 is displayed, enter the correct username and password and log in again. Note: If the DSL light on the modem is still not on when redialing, it may be due to a line problem that needs to be repaired by the telecommunications office. If the DSL light is normal but still can't access the Internet, it may be due to a problem with the main server or a problem with the Internet service of the community, and you need to contact the property management of the community.
3.If the fault cannot be eliminated after closing all the windows that are using the dial-up software and the Internet Explorer window that is surfing the Internet, restart the modem again. If the modem still does not resolve the fault after restarting, observe what the error message is. If the error message is 678 or other line or primary server related prompts, contact your local telecommunications office for their assistance.
4.If the modem does not fail after a restart and the error message is related to the primary server or line, then it is recommended that you restart the computer to try to troubleshoot the fault.
3. Special faults and solutions.
Since there aren't many computer users in the region, there shouldn't be any dropouts at the bandwidth limit of 20% of the total capacity. However, recently the community is undergoing line transformation, if the cable terminal is not connected well or wrong during the transformation process, it may cause the line to be broken, resulting in the inability to access the Internet normally. In this case, you should contact the property management department to seek their help.
