The network is now disconnected, some computers can t connect to the Internet, and sometimes the ser

There are several possibilities for disconnection:1It's a small chance that you're having a problem with your physical connection.

2.Insufficient bandwidth for your current web application and need to increase the bandwidth.

3.Someone uses BT software to maliciously grab bandwidth, causing you to be unable to use the network normally. Or someone uses some network management speed limiting software to restrict the following machines.

4.Viruses in the LAN computer keep sending junk data to the network, blocking your normal data passage.

I have not summarized the above points completely, but it is difficult to really check them. There is currently a router on the market called Immunity Wall, which seems to solve several of the problems I listed.

Now the network is disconnected, stuck and other problems, their method is more able to solve the root cause, they manage each terminal. Each terminal is forbidden to send spam messages to the outside world, and there is no source of attack. The problem is solved.

1 The network leader is not doing a good job, or has poor contact.

2 ARP attacks.

3 Attacked by DOS.

4 The line is not good.

5 P2P preempts bandwidth.

6 Restricted by network management software.

7 Network equipment overheating.

Try the LSP repair tool, try 360 and many other antiviruses, if this happens suddenly, it should be a virus or a problem with the network itself.

1. Click the networking icon in the lower right corner of the desktop, click [Open Network and Sharing Center], 2. Find the network you are currently connected to (the access type is Internet), and click the blue part behind the connection, as shown in the figure

3. Select the Internet Protocol version 6 and 4 in the network, and double-click it successively.

4. Set it to [Automatically get IPv6 address] and automatically get DNS server address, and click OK after the setting is complete.

In the same way, modify the settings in version 4 of the agreement. When you're done, restart the network and you're ready to surf the Internet.

Go to the command prompt and type ipconfig

all, check the current IP information, and whether the IP information is obtained normally.

How do I know if the network is working? QQ can be on, but the web page can't be opened? You describe it clearly.

If it is QQ can be on, the web page cannot be opened, that is, there is a problem with DNS, open the network sharing center, view the active network, click wifi or limited link, attributes, double-click IPv4 to set the regular to: automatically get IP, automatically get DNS

The solution to frequent broadband drops is as follows:

1. If you use a router, disconnect the router for stand-alone dial-up test;

2. If you have a modem device, please pay attention to whether the device is overheated, and it is recommended to turn off the digging team for a few minutes and then restart it;

3. If the connection is dropped when running the program alone (such as when playing games), it is recommended to restart the computer or reinstall the program;

4. Check whether the disconnection is caused by computer virus, and it is recommended to scan the whole disk;

5. If there is a server option for the running program, please select China Unicom.

If the above methods still cannot solve the problem of disconnection, you can contact the local manual customer service for feedback.

The problem of disconnection is more complicated

1. Turn off the cat's power and let it cool down before turning on the teasing. Because cats may not be normal after working for a long time in the socks.

2. If pressing 1 fails to solve the problem, it is very clear that the mountain can be a problem with the line, you can call ** to the business hall, and they will deal with it.

3. The virus will also cause the connection to drop, try to kill and kill the virus.

It may be caused by an incorrect gateway setting on the router, a gateway hijacking caused by a computer poison, or an LSP hijacking.

You can use the "DNS Selection" and "LSP Repair Tool" in the 360 Tools Encyclopedia to solve these two problems, restart the computer after the repair can be restored to normal, if you still can't access the Internet after restarting, then check whether the LSP and DNS have been successfully modified, if you can't modify it normally, it is a stubborn interception caused by a Trojan, and you need to repair it after comprehensive antivirus.

1. Check whether the interface between the cat and the router is loose (this is the most common) 2. Re-set the router and observe whether it is still in this condition (to determine whether it is a router setting problem).

3. Pin the router to see if there is a network fault (to determine whether it is a router hardware fault).

4. If there is no problem with the previous inspection, it can definitely be a cat problem or a network problem, you can call ** to the network service provider and let them solve it for you.

Do you stop the router for a while and try again?
