Broadband failure. First, the fault phenomenon.
Users report slow Internet speeds, slow web page openings, and unresponsive gateways.
Second, the analysis process.
Based on the situation reported by the user, the possible cause of the failure is speculated. First, observe whether the status indicator of the user's modem is normal, if not, it means that the modem is no longer working properly. Secondly, check the status of the NIC on the computer, if the NIC indicator is abnormal, it means that there is a problem with the connection between the NIC and the modem. Thirdly, ping the IP address of the machine, if it cannot be pinged, it means that there is a problem with the network card of the machine. Finally, ping the gateway, if it doesn't work, there may be a problem with the line between the unit and the gateway.
3. Processing steps.
1.Check whether the status indicator of the modem is normal. If it doesn't work, restart the modem or turn off all devices, wait a few minutes and then turn it back on.
2.Check whether the status indicator of the network card on the computer is normal. If not, check whether there is a problem with the connection of the network cable, including the network card, network cable, and modem.
3.Enter the ipconfig all command in the CLI window to check the IP address of the machine. If the IP address of the machine cannot be obtained, the NIC is faulty.
