This article introduces the relevant knowledge of "how to troubleshoot the network in win7 LAN". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

1. First, you can use the ping command to try to ping whether the computer near the error point is working. In this way, we can determine whether it is a single network problem or a local network problem.

two。 If it is a single network problem, just look at the computer network settings on the computer. If it's a local problem. You need to find the nearest switch that reported the wrong point. Try rebooting.

3. If it hasn't been solved, check to see if the port of the network cable is good. Use the tool to detect the network to find this network cable to check and confirm. 1-2-3-6 lights must be on in order to pass.

4. If the light of 1-2-3-6 is not on, it means that there is something wrong with the network cable or port. At this time, you can use the network testing tool to connect both ends of the network and take a look at the whole network cable. Try to solve the problem by making a new crystal head.

5. If there is nothing wrong with the network cable, you need to see if there is a problem with the switch. Change the nearest switch. And then test it with ping. The most troublesome situation is: when a computer's network card is broken and causes a network failure, you have to use ping IP (gateway)-t side ping gateway, while unplugging the network cable one by one. To find this computer. The problem is resolved after replacing the network card. In addition, find the core switch and see if the outgoing network port is open.

6. Find the core switch and clear the ARP table. In case of IP conflicts. Then enter the core switch as an administrator, find the ARP table, and delete all static and dynamic table entries. Finally, rebind the ARP. In case of IP conflicts.
