Question 2: What should I do if the computer network connection is broken? The computer network connection was disconnected for the following reasons:

1, the password of the dial-up account has been forgotten, or the password has been modified but I forgot it myself. First of all, I suggest you think it over and try it several times. If not, look for the previous Internet application list, which is usually recorded; I can't find the list of handling the network. Call the service provider to get the password back. Please dial10000 for telecom,10000 for China Unicom and10 for mobile. Please prepare the certificate in advance when handling the network cable, and the customer service staff will check the information.

2. There is something wrong with the operator's network: power failure or other unexpected accidents (earthquake, tsunami, solar electromagnetic storm, etc.). ), so I can only wait.

3. There is something wrong with the network cable or route at home: it needs to be carefully checked and tested. If not, you can ask the operator for help.

4. Computer network card hardware or software failure: close and restart or download the driver again.

Question 3: What should I do if the crystal head of the computer network cable is broken? Take off the original crystal head and throw it away. . . That thing is disposable. . .

Redo a crystal head (RJ45 head) on the broken wire. .

Crystal heads range from a few hairs to one or two pieces. . You get what you pay. . . .

Question 4: How to check whether the router is normal when the computer network is broken;

You can power off the router 1 minute and then restart it;

Check whether the network cable connection is normal;

Question 5: How to connect the computer network cable when it is broken? The network cable is not expensive, just change another one.

If it must be connected, it is better to connect an adapter, which is more stable.

If the copper wires of the same color are directly twisted together, it is possible, but it is unstable.

Question 6: The computer network is completely disconnected. What should I do now? I don't know how to contact.

Question 7: If the network cable is broken, how can the computer display the network icon with a cross, or a yellow exclamation mark at the lower right, or search by itself?

1) If it is a broadband problem, directly connect the broadband network cable for testing. If it is a broadband problem, contact broadband customer service to solve it.

2) If it's a router problem, if it worked before, it won't work for the time being. My own way is to disconnect the power of the router and plug it in. See you later. If it can be restored to the factory settings, it can be used in strict accordance with the instructions. You don't understand, so it is not recommended to set it at will (this is sometimes caused by the slow or failed IP address search of the router under the premise of correct physical connection, not the router is broken).

If I can't solve it all the time, I suggest calling the customer service of the router. They have telephone online guidance. If I encounter problems that I can't solve, it is very useful to ask their advice. They will provide correct advice for your setup or operation.

3) If the wireless switch is off, just turn it on. If it is a software wireless connection, the software is not easy to use, and it is normal to have problems frequently. There is no better way to use a router. In addition, the network card driver is not suitable or not suitable, and there is something wrong with the network cable interface or network cable.

4) If it is caused by system problems, it is recommended to restore the system or reinstall it.

Question 8: What should I do if the computer keyboard cable is broken? The cost of repair is not as good as replacing it with a new one. You can buy a single keyboard. Now 10 is a few dollars short, and a good one like Logitech is only 50 dollars. . . . Besides, the cost of repairing it is enough for you to buy a new one.

Question 9: What should I do if the computer network cable is broken and I can't get online? Check whether it is disconnected, connect the network cable, or call 10000 for customer service.

Problem 10: The computer network cable is broken. Will it affect the network speed? Due to the particularity of network cable, the internal structure is twisted pair. When it is disconnected, the internal structure of twisted pair will change, which will affect the packet loss when the network cable transmits data and increase the mutual interference between twisted pair lines. As the saying goes, unstable. The suggestion is to replace the network cable.
