There will be many problems during the use of the router, and it is also very common to have a router fault. So I have studied how to solve the router fault correctly. I will share it with you here, I hope it will be useful to you.


1. fault description

Some of my friends opened a small Internet cafe before the summer, with 70 or 80 computers in the Internet cafe. They all reflect that sometimes a strange phenomenon occurs when surfing the Internet: some computers cannot access the Internet at a certain time, but other computers can access the Internet normally. For example, two computers connected to the same server are playing online games. When the above problem occurs, one computer may still play online, but the other computer is disconnected, then, you cannot access the game in any way, and even the web page cannot be opened normally.

2. Fault Analysis

According to a friend's description, I found that all their Internet cafes use the same network topology. Through fiber cascade switches, switches are connected to routers, from the perspective of the same problems in the Internet of Internet cafes, the reasons for the network problems of these Internet cafes should be the same.

I rushed to my friends's Internet cafe to check whether the computer in the LAN can be normally connected, so I suspect that the fault is not on the switch, but on the router. Check the internet cafe routers and find that these Internet cafes purchase low-end routers that are cheap to save costs. I suspect that these routers may fail to "bring" too many users to access the Internet at the same time because of their poor performance. Therefore, I borrowed a high-end router from the data center. After the installation, all the computers in the internet cafe were able to access the Internet normally. After two days of operation, no Internet access was found. It turns out that the router performance is too poor, causing a fault.

Because this fault is caused by poor router performance, I suggest you buy a high-end router. However, a friend just regards Internet cafes as a tool to make money and is reluctant to spend too much money on network devices. Finally, the author only sets an idle server in the internet cafe as a proxy server for some computers to share the Internet, while the router connects to other computers to access the Internet. After the configuration is complete, after a period of testing and running, although the current network speed cannot catch up with the network speed when using a high-end router, but there is no problem, the network operation is also stable, the fault was solved without increasing expenditure.

4. Summary

Most Internet cafes aim to make profits. Many people adopt measures to save money and buy cheaper devices. In this way, although the cost is reduced, the performance of the equipment is reduced, while the Internet users go to the Internet cafe where the computer is good and the network is good, the poor network of Internet cafes naturally won't attract customers, and adding devices will inevitably waste part of the money. Because, when creating a network, Internet cafes should not only save money, but also pay more attention to network performance. They should first know the size and operation mode of Internet cafes and select suitable network devices to build a reasonable network, in order to make money in Internet cafes. How can an overwhelmed router take on the responsibility of making money from Internet cafe owners?
