Broadband failure. 1. Broadband troubleshooting process.
1.1. Judge the fault phenomenon.
Before repairing a broadband fault, it is necessary to determine the fault symptoms, such as unstable network, inability to connect to the Internet, slow network speed, etc. It can be judged by the following steps:
1.See if your PC is able to connect to your router or cat.
2.Check whether the NIC of the computer is normal and whether the IP address can be obtained.
3.Check whether the indicators of the router or the cat are normal, especially the network ethernet port light and broadband port light.
4.If there are no problems above, you can try ping to test whether the telecom gateway and DNS server are normal.
1.2. Troubleshoot the cause of the fault.
According to the fault phenomenon, you can roughly determine the cause of the fault, such as network line problems, router or modem faults, computer system setting problems, etc. You can troubleshoot by following these steps:
1.Check whether the network cable is normal and whether it is damaged or aging.
2.Check whether the router or modem is working properly and whether it needs to be restarted or reset.
3.Check whether the computer system settings are correct, especially the IP address, DNS server, etc.
4.If there is no problem with the above, you can try to change the computer to test whether it is a computer system problem.
1.3 Problem solving.
According to the fault cause, take corresponding measures to solve the problem. For example, if there is a network cable problem, you can replace the network cable; If the router or modem is faulty, you can restart or reset the router or modem; If it is a problem with the computer system settings, you can reset the IP address, DNS server, etc.
2. Common broadband faults and how to deal with them.
2.1 Network cable problems.
The network cable is an important device for connecting broadband, and if it fails, it will affect the normal use of the network. Common network cable faults include: aging and damage of network cables, loose crystal heads, etc. In response to these failures, corresponding measures can be taken to deal with them. For example, if the network cable is aging or damaged, you need to replace it with a new one. If the head is loose, you will need to remake it.
2.2 Router or cat issues.
A router or modem is one of the important devices to connect to broadband, and if it fails, it will also affect the normal use of the network. Common router or modem faults include: no signal from the router or modem, abnormal indicator light, etc. In response to these failures, corresponding measures can be taken to deal with them. For example, if the router or cat has no signal, you need to check whether the signal cable is plugged in; If the indicator light is not normal, the router or cat needs to be reset.
2.3 IP address issues.
An IP address is a unique identifier for a computer on a network, and if the IP address is not set correctly, it will lead to network connection problems. Common IP address issues include IP address conflicts and IP addresses that cannot be obtained. In response to these failures, corresponding measures can be taken to deal with them. For example, if there is a conflict between IP addresses, you need to set a new IP address. If you cannot obtain an IP address, check whether the network connection is normal.
