Why does the Internet always drop after a while?

I think there are four common reasons for disconnection.

1. Do you use Kaspersky Antivirus or Kaspersky Firewall, or is it similar to Kaspersky's incognito mode function? If yes,Then you just turn off this incognito mode,Don't be incognito on the network, this situation won't occur after stealth,Invisibility sometimes affects BT** speed,There is also P2P network TV。 A reboot of the machine or cat can sometimes do the trick, but it won't solve the problem at all.

The fundamental reason for this situation is that the broadband network you use (such as telecommunications, Netcom, Tietong, etc.) often has to detect your computer, and this situation will occur when the other party cannot detect your computer network card, and when this situation occurs, your network card does not get the IP address at that time, so this situation will occur.

It's not a big problem, though. Generally, this problem is not easy to occur, unless the broadband network you use needs to be adjusted to the network.

2. Check whether there is strong magnetic field interference in the place where the network cable passes.

Third, the cause of static electricity, friction has static electricity, let alone the computer. The computer's computer source conversion and display will produce static electricity, especially the computer's power conversion is in a high-frequency oscillation state of 500kHz is the most culprit of the chassis electrification, find a piece of wire, connect it to the ground wire on the power socket, and connect the other end to the iron post on the window sill. You can measure the voltage change of the front and rear chassis, which is not small.

The normal chassis voltage should be around 3 volts (I haven't measured it myself, my friend said, there should be no problem).

Fourth, in addition, there are certain requirements for the first line to use ADSL modem to access the Internet, one is that each joint of the line should be connected, and the other is that any equipment can not be connected before the ADSL modem separator, such as: ** extension, anti-theft device, etc. When reconnecting the binding post of the junction box, it is best to wipe the ** wire and the binding post with fine sandpaper, and wrap the ** wire on the binding post a few more times when wiring, and then tighten the screws to ensure good contact.

Remove the first socket at home, use direct wiring, it is best to use welding when connecting wires with wires, and then wrap them with insulating tape, anyway, you can't connect any equipment before the separator, so as to ensure that the line contact between the junction box and the adsl modem separator is good, and the quality of signal transmission is ensured.

And then there's the problem of the operators themselves, but it's unlikely.

Original answers. If you still have questions, you can send me a message.

It's a matter of the server of the broadband service provider.,Some time ago, I changed the line.,Hit ** to explain that the situation is solved.。

It is possible that there is a conflict between the address of the NIC and the NIC address.

It should be your network is unstable.,It has nothing to do with the computer.,You don't have to restart it.,You double-click the Internet icon in the lower right corner.,Click to disconnect.,And then connect it.,My school often does this.。

It may be a broadband problem, you can turn off the cat before going online, and when you turn on the computer, you can turn on the cat, try when I just got it back, I just can't get it up, and it also drops, and maybe it's good to pass naturally.

Is the power supply not plugged in properly.

Which is that your network is not very good, and it has nothing to do with the computer.

Check the cat router, network cable, ** line, and computer system network card, etc.
