The onboard network card is often disconnected, so just dial out the network cable and replug it. An

It's not a problem with the network card and software, I've encountered this kind of problem. The interface is bright, and the ping seems to be fine. It is recommended that you take a closer look at the interface of the network card to the place where you want it to be, whether there is a certain needle corner rusty, and wipe it with a pencil or something.

If there is still a problem, change the address to a fixed one, and don't get it freely. There is also whether your crystal head is correct for 8 pins, it is recommended to test it, or try to change a network cable with others.

Several computers are using one route together, and it is likely that which computer has a virus. You can first rebuild your computer from the system or antivirus (preferably from the one), and then put the network cable for your own use to test if it doesn't drop, it is estimated that someone else's computer has a virus.

There is also the fact that others use the computer to steal the flow rate of your network, causing congestion after hanging the line.

It's just a personal opinion, and I've had similar problems before.

Hello, your question should wipe the onboard network card problem, what motherboard are you using? If you can, it is recommended to change the motherboard, if you don't change it, you can buy an independent network card and plug it in to try, the independent network card is very cheap about 20 yuan.

Once the ping is on, try 360 Browser!

I'm going to do that all the time.

It's OK to add an independent network card.

This one. My classmates also have this problem. Maybe there's a problem with the network card. See if your network card chip is good.

ARP attacks?

Try ARP Antivirus Attack.

It's normal to turn on the firewall and drop the network, I've turned it off, and it is not recommended to open the firewall if you use it at home.

Are you new to your router?

It's not a problem with the network cable, but it could be the following:

One is the poor contact of the crystal head, the ordinary crystal head used at the beginning, after a long time, this situation will occur, you can change to a more advanced crystal head, and redo it.

Second, you may be connected to the network through routing, in the configuration table of routing, someone may have modified, shielded your MAC address, there may be such a phenomenon, third, the driver of the network card is damaged, reinstall the driver.

The easiest way to do it. Use a 360 disconnected first aid kit. Fix it.

It's not a network cable issue. The computer problem is solved at once.

Is it a poor network cable contact?

Hello:A red cross for your network connection appears in your computer's notification bar.

Typical phenomenon.

Network connectionPoor contact that occurs.

The reasons are: The quality of the crystal head of the network cable is not good, and there is a virtual connection inside; , the modem's power adapter is in poor contact; , the network input line (** line or optical fiber) line is faulty.

The motherboard has an integrated network cardThe likelihood of failure is low.

Testing is done, and symptomatic treatment is done depending on the cause.

Using the elimination method, first determine whether there is a problem with the network cable, replace the network cable to a terminal, eliminate the network cable, and then the network card, if it is a route sharing, check the routing interface end.

If you make sure that the network cable is good, it is the network card.

Unplugging and unplugging the NIC cable generally does not cause data loss on the onboard NIC because the NIC design usually includes the stability of the physical connection and the reliability of data transmission. However, if you do not follow the correct steps when unplugging and unplugging the NIC cable, or if there are other problems, it may lead to data transmission interruption or data loss. Here are some of the possible reasons for such issues:

1.Branch interruption due to power failure: If the computer or network device suddenly loses power during the process of unplugging and unplugging the network card cable, this may cause data transmission interruption and data loss.

2.Poor contact of the socket: If the socket is not fully inserted when inserting the network cable, or if the socket is loose or dirty, this may lead to poor contact between the plug and the socket, which in turn affects the stability of data transmission and causes data loss.

3.Driver or hardware issues: If there is a problem with the NIC driver or if the NIC hardware itself fails, some or all of the data may be lost when unplugging the network cable.

It should be pointed out that these situations are abnormal regrets, and in most cases, unplugging and unplugging the network card cable will not result in data loss. However, in order to ensure the stable transmission of data to the greatest extent, it is recommended to follow the correct operation steps when unplugging and plugging the network cable, such as disconnecting the network cable first, gently unplugging the network cable, etc., and ensure that the network cable and socket are clean and in good contact. In addition, it is important to update and install the appropriate NIC drivers in a timely manner to ensure stable transmission.
