This situation may be caused by your network cable socket being too loose, and you can find a way to fix the network cable tightly.

It is also possible that there is a problem with the crystal head of your network cable, you can cut the crystal head of the network cable and make it from scratch, of course, you can buy a network cable to replace it.

The internal line connection of the crystal head of the network cable is not good, so it will lead to such a problem, the easiest way is to get a crystal head from the new, but there is a problem, no one will give you a door to get this, the crystal head from the new to have special pliers, buy a handful and not suitable, so it is recommended that you look at the color of your network cable, and then spend a few yuan to buy a network cable with crystal heads at both ends, and then come back to cut off, the corresponding color of each line and your network cable is cut off after the connection can be, Although it is a bit troublesome to change the crystal head in this way, it is also a good way to save money, or cut off a section of your network cable to go to the computer city and let him give you a crystal head, the problem is that the network cable at home is too hard, and the crystal head will appear loose internal wire,,, you refer to it yourself,

Try redoing the crystal head of 2 heads.

Poor contact, try it again.

That also needs to be checked.

There is no problem with the computer's network socket.

There is no problem with the plug at the other end of the network cable and the socket of the router.

Make sure that your computer and router are properly connected.

If there is a problem with the network cable or network card, update the network card driver and try it, and use the driver wizard.

A few possibilities.

The crystal head of the network cable is broken.

The network cable interface is broken (where the network cable comes out of the wall).

The computer network card is broken.

Most likely, the crystal head is broken.

The second is that the interface is broken.

Finally, consider buying a network card for more than 10 yuan.

If the network cable is broken or the contact is poor, check the entire line of the network cable.

If the display network cable is not plugged in properly, and there is a fork in the small TV in the lower right corner, it is not plugged in or there is a problem with the physical interface. Let's check the outside line.

Check if the computer interface of the network cable is not plugged in? Check if there is a flashing yellow light and a solid green light.

First of all, it is certain that if the prompt is not plugged in, it must be a physical connection problem. It will cause intermittent contact, which is generally the contact problem of the crystal head of the network cable. Changing the thread should rule it out.

ps: The network card of some brand machines may be more mouthful, that is, the requirements for the specifications of the crystal head are stricter. That's why some cables can be used on other machines, but not on one machine.

PS2: The landlord can go to Hongtu triplets to buy the original network cable, generally about 10 yuan for 2m.

If you have a problem with the plug of your network cable, make a new plug.

This will happen if the crystal head is not connected.

My computer used to be like this.,Maybe there's something wrong with the hard disk of your computer.,Otherwise, it's a virus.。。 You'd better find someone to fix your computer. or network connection companies.

As you said, there is a high probability that it is caused by thunder, and the ISP's line has been interrupted, so it is recommended that you consult the ISP.

I've had the same problem, it's especially easy to drop on rainy days, it's a line problem, maybe it'll be fine in a few hours, if it doesn't work, you can call 10000 for help.

First, your network cable is good.

Second, your port is good.

Third, your modem is good.

Fourth, your computer's network card driver is installed (very important).

Fifth, make sure you're plugged in and see a flashing light on the interface to the computer!

Then click on Diagnostic Repair, which will find out your problem.

BAI of the Internet

Time to prompt the network.

The DU cable is not plugged in properly, usually because the DAO card is not plugged in or the NIC version driver exists.

If you have a right problem, it is recommended to reinsert the network card or reinstall the driver to try again, and pay attention to whether the network cable and network card interface are normal, and try to change the network cable.

In addition, if there is a problem with the working mode of the network card, it will also affect the use, you can find the "My Computer" icon of the computer, right-click, select "Management - Device Manager - Point to the Network Adapter", find the network card, and then right-click the network card, in "Properties--- Advanced - mediatype or link speed", set the working mode of the network card to 10m half-duplex.

There are a couple of questions, 1It's true that the network cable is not plugged in.,Including the computer side and the router interface side.,It's like this if it's not plugged in anywhere.,2.Poor network cable contact, 3

The network signal is sometimes good and bad. 4.The network card is not installed properly, or there is a problem with the driver.

I've encountered it once, that is, there is a problem with the driver of the network card, and it is OK to reinstall the driver, of course, the premise is that there is no problem with the network cable, and the network interface is no problem. Thank you! I hope my advice is helpful to you! Thank you!

Your network cable is loose, and the router will try to change the socket.

The problem is still the connection, that is, your network cable. Generally, pull out the interface at both ends of the network cable and plug it back in to see if there is a connection, if not, try to replace the crystal and head.

General issues can be solved.

The network cable, the crystal head is no problem, that is, there is a problem with the network card.

I encountered it when I was on the LAN at school, and you should have a LAN bar too.

At that time, I didn't solve it much, just look at your network card socket, unplug the crystal head that has nowhere to plug in, such as connecting the switch or other switching equipment, start those switching equipment from the new, there should be no problem!

It should be that the network cable is in poor contact, check the interface crystal head.

Maybe it's because the line of the ** line is not done well, or because of the ** line, it's a little bit of poor contact, you should go to change the ** line, or call the people of Netcom to take a look

Why do you need a local connection to surf the Internet?

Right-click "Properties" in "My Computer", look at "Hardware" -- Hardware Device "See if there is a network card driver" network adapter "If there is a yellow one"? Or a red cross, indicating less drive or less hardware.

Does your computer use the cat directly to access the Internet or add a router? If you are using a router, you also need to set it: "Local connection". The relevant settings are at: "Start" - Settings - "Network Connection".

You can right-click on your network connection, there is a property, look at your network card configuration, there is a link speed and duplex in the advanced. You change it.,Don't try it automatically.,There may be this problem.。。 Because I've come across it before.

Brother, if you don't plug it in, you plug in the network cable, the red fork is out, what kind of driver is installed? If it doesn't respond when plugged in, the network cable is fine, isn't that the network card broken?

If you want the staff to go to the computer room to adjust your bandwidth wider, there is also the system itself retains 20% of the bandwidth, you can limit it, method: type "command" in the "Run" dialog box to open the "Group Policy" window, and then find the "Network" item from the "Management Template", there is a "QoS Packet Scheduling" item, and then you can see a "Limit Reservable Bandwidth" item under the "Settings" column on the right side of the window, double-click the item, you can see the "Bandwidth Limit" here The default value is 20%, and we can maximize bandwidth usage by changing it to "Enabled" and changing the "Bandwidth Limit" value to "0%". ”

Reinstall the driver. There may be a problem with the drive.
