This article mainly introduces the common network failures, which have a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, let the editor take you to understand it.

There are ten common network failures: 1, the setting of the network adapter conflicts with the computer resources; 2, there are two network segments in the local area network, in which all computers in one network segment cannot access the Internet; 3, all computers in the entire local area network cannot access the Internet; 4, in the local area network, no clients can access the Internet except the server.

Ten common network failures:

1. Failure phenomenon: the network adapter (network card) settings conflict with computer resources.

Analysis and elimination: by adjusting the IRQ and I / O values in the network card resources to avoid conflicts with other computer resources. In some cases, conflicts with other resources need to be adjusted by setting the jumper of the motherboard.

two。 Malfunction: other clients in the local area network can see each other on the "network neighbor", but only one computer can't see it, and it can't see any other computers. (premise: the local area network of the Internet bar is connected to a star network structure through HUB or switch.)

Analysis and exclusion: check whether the computer system is working properly; check the network configuration of this computer; check whether the network card of this computer is working properly; check whether the network card settings on this computer conflict with other resources; check whether the network cable is disconnected; check that the network cable connector contact is normal.

3. Malfunction: there are two network segments in the local area network, and none of the computers in one network segment can access the Internet. (premise: the local area network of the Internet bar is connected to two network segments through two HUB or switches)

Analysis and exclusion: the trunk of two network segments is broken or the connection at both ends of the trunk is poor. Check the settings for this network segment in the server.

4. Malfunction: all computers in the local area network can see each other on the "network neighbor". (premise: the local area network of the Internet bar is connected to a star network structure through HUB or switch.)

Analysis, exclusion: check whether the HUB or switch is working properly.

5. Failure phenomenon: a client in the local area network can see the server on the "network neighbor", but can not access the Internet. (premise: server refers to the computer that acts as an agent for Internet cafes and other airliners on the Internet, the same as below)

Analyze, exclude: check the TCP/IP protocol settings for this client, check the IE browser settings for this client, and check the server settings for this client.

6. Malfunction: all computers on the entire local area network cannot access the Internet.

Analysis and exclusion: whether the server system is working properly; whether the server is offline; whether the modem is working properly; whether the office is working properly.

7. Failure phenomenon: in the local area network, no other clients can access the Internet except the server.

Analysis and exclusion: check whether the HUB or switch is working properly; check whether the network part of the connection between the server and the HUB or switch (including network card, network cable, connector, network configuration) is working properly; check whether the software of the agent surfing on the server starts and runs normally; whether the setting is normal.

8. Failure phenomenon: during the dial-up operation, the MODEN has no dial-up voice, can not connect to the Internet all the time, and the light on the MODEN does not flash.

Analysis and elimination: whether the telephone line is busy; whether the connection of the server connected to MODEN (including: connection, connector) is normal; whether the telephone line is normal, with or without noise interference; whether the dial-up network configuration is correct; whether the configuration setting of MODEN is correct, and check whether the audio or pulse mode of dial tone is normal.

9. Symptom: MODEN is not detected by the system (if MODEN is normal).

Analysis and exclusion: reinstall MODEN and pay attention to the correct location of the communication port.

10. Malfunction: too slow to connect to the Internet.

Analysis, exclusion: check the server system set in the "dial-up network" port connection speed is the set maximum; whether the line is normal; by optimizing the MODEN settings to improve the connection speed; by modifying the registry can also improve the Internet speed; at the same time, the Internet is many clients; if many, so that the connection speed is too slow is a normal phenomenon.

Thank you for reading this article carefully. I hope the article "what are the common network failures" shared by the editor will be helpful to everyone? at the same time, I also hope that you will support and pay attention to the industry information channel. more related knowledge is waiting for you to learn!
