A disconnection is when an Internet Multiline Chat (IRC) network is used, and a netsplit is a loss of contact between two IRC servers.

Expansion: 1. When using the Internet Multi-Line Chat (IRC) network, Netsplit is the phenomenon of loss of contact between two IRC servers. As a result, one party chatting suddenly sees the other person disappear.

Most netsplits can be recovered within a short period of time.

2. IRC networks are usually linear topologies. This means that each server connection is directly connected to the other server. When the two service return sock dispensers lose contact, the network is split into two parts.

Users are still connected to users on that part of the network they are on. If the network is a mesh topology, each server can pass information to the other server when the first server is lost.

Frequent disconnection of the wireless card may be due to the following reasons:

1. Poor contact between the wireless network card terminal and the card body. If the contact is not good, it is easy to disconnect, it is recommended that you can try to put this card in other normal terminals for testing;

2. The 3G network signal in the area is not good. Weak 3G network signal will also lead to frequent disconnection, you can consult relatives and friends who use Unicom 3G wireless network card to see if they have encountered the same problem, if so, you can report the signal problem to the local 10010, and the staff will deal with it after verification;

3. Check whether the computer has viruses. If there is a virus in the computer system, it may also cause the wireless network card program to run incorrectly and the connection will be disconnected. You can use anti-virus software to check and kill your computer to see if it has been infected with a virus.

4. There is a problem with the wireless network card or wireless network card terminal. If there is a problem with one or both of the Wi-Fi SIM card and the Wi-Fi SIM terminal, the connection will also occur. After the elimination point, you can go to the nearby Unicom business office and ask the staff to check for you to see if there is any problem.

1.Most of them can't connect to the Internet. First of all, it is more common to see the "Network Adapter" in the "Device Manager", or the "Network Adapter" is wrong, no matter how you update the driver, there is a yellow exclamation point and then the network protocol is not working properly

Click "Start" - "Run", enter "cmd" and then enter "ipconfig all", if the network card is broken, the correct MAC address will not be returned, and the IP may also be returned Error Now they are all integrated network cards, which are generally rarely broken, even if they are broken, the problem is not big, just buy a second-hand network card and replace it, at most 10 yuan.

2.If the network card is broken, generally your computer will not have a local connection, the network network adapter cannot be found in the device manager of the system, or a yellow exclamation mark is displayed, the driver cannot be installed, etc., and the local connection will not appear; Sometimes you connect but you never receive packets or you can't send them. The number of packets sent by your computer and the amount of data received may be due to network cable problems, or it may be caused by transmission distance.

This does not necessarily mean that the more you receive is good, but it depends on the problems you have.

According to your description: first of all, you need to judge the situation when the broadband connection is dropped, and according to different appearances, you can really find the real cause of the disconnection. The following is a targeted solution according to various disconnection phenomena:

1) A small red cross appears in the lower right corner of the computer when the connection is disconnected. Suggested solutions: It may be caused by poor network cable contact, network card hardware failure, or abnormal power supply of network equipment such as ADSL modem, and it is necessary to fix the network cable, equipment power supply or replace the network cable.

2) A small yellow exclamation mark appears in the lower right corner of the computer when the connection is disconnected, and it is suggested that the solution may be caused by poor network cable contact, network card hardware failure, or abnormal power supply of network equipment such as ADSL modem, check whether the ADSL modem status light is normal, and replace the network cable, restore the initial settings of ADSL, etc.

3) Disconnection when playing a game, but the webpage opens normally when the connection is droppedSuggested solutions: Some computer programs (such as firewalls and anti-virus software) may conflict with game programs, or the game service may be busy. It is recommended to change the game service area and exit other applications while playing the game.

4) Browse the web disconnection but QQ and other programs are normalSuggested solutions: Make sure that only one computer in your network is using the network, if there are multiple computers surfing the Internet at the same time, it will cause the opening of the web page to be abnormal. In addition, you need to check whether the computer browser is normal, it is recommended to change the browser or change the computer to try again.

The network card will not be dropped, if the local connection is dropped, you check the crystal head, if the network card can not be detected, the single plug will appear this problem, that is, the network card is dirty.

This may be related to the operator, or it may be related to your device, you first check if there is a problem with your device, if there is no problem, it is a problem on the operator's side.

Is it your own home? Poor contact Check out the interface!

If the computer is connected to the router to access the Internet, and the computer is often disconnected, it may be a line problem and the connection is not good. The solution is to start all over again.

If the above methods still do not work, you can infer whether there is a problem with the router, and many routers on the market now have vulnerabilities. As a solution, restart your router, or just try a different one.

Then there is the problem of the computer itself, and the basic network card driver related to the network is also the machine, so check your network card driver. First, update the NIC driver, if it has been updated, you can delete it and reinstall it. There is also the file corruption of the network component of the Windows system, and the solution is to restore or reinstall the system.

In addition, there may be a virus, which will cause the IP communication between the computer and the gateway to be abnormal, resulting in a disconnection. The solution is antivirus, borrowing major antivirus software to scan the whole machine for antivirus.

If you are on a local area network, in addition to the above possible reasons, there are also computer IP conflicts in the local area network, such as duplicate IPs, resulting in frequent drops. Solution: Set the IP address again to avoid duplication.
