Broadband failure. 1. Fault judgment method.
To check whether the broadband signal is normal on the user side, you can judge it from the following aspects:
1.Whether the user's device (such as computer, mobile phone, etc.) can connect to the network normally, you can try to access other** or use other applications for testing.
2.Check whether the network cable of the user device is plugged in properly, check whether the network cable is loose or broken, and if there is a problem, you can try to replug the network cable or replace it with a new network cable.
3.If the network settings of the client device are correct, including the IP address, subnet mask, default gateway, and DNS server address, you can try to set the network parameters again or contact the network administrator.
4.Whether the client devices can be connected to network devices such as routers or switches, try restarting the devices or checking whether the connection cables are normal.
2. Common faults and solutions.
1.Faulty network cable: The network cable may be loose, broken, or damaged, you can try to replug the network cable or replace it with a new network cable.
2.Router fault: If the router is faulty or incorrectly configured, you can try to restart the router or reset the network parameters of the router.
3.DNS server fault: If the DNS server is faulty or the DNS server address of the client device is set incorrectly, you can change the DNS server address or contact the network administrator to set the DNS server address.
4.Modem failure: It may be that the modem is faulty or there is a problem with the cable between the user device and the modem, you can try restarting the modem or checking whether the cable is normal.
5.Port fault: It may be a faulty port of a device such as a modem or router, and you can try to replace the port or contact a maintenance personnel for repair.
The above are some common broadband faults and how to solve them, but the specific situation may vary depending on the network environment and equipment. If the preceding methods do not solve the problem, we recommend that you contact the network administrator or maintenance personnel for further troubleshooting and maintenance.
