In the afternoon, the computer was disconnected and could not be connected again until late in the e

I don't know if you are connected to the router more than one person to go online, if it is a stand-alone cat to test the cat and the external line, the problem of the external line you find the operator to go, if you connect the router, it is likely to be a virus attack on the internal network. Currently, there are ...... ARP attacks, skulls, DDoS, and oversized ping packets in the intranetA series of intranet attacks can cause intranet disconnection, and even attacks like ARP are difficult to detect, and antivirus software can't solve them, and they can't be **. This is also the main reason why the intranet disconnection cannot be solved after the system is reinstalled.

Like a lot of people, you have no choice but to use software to limit your speed. The only effective way to solve this problem once and for all is to deploy an immune network solution with immunity wall technology. Solve the problem directly from the root cause of the network problem - the network card, block the intranet virus attack from the network card, and accurately locate and alarm the abnormal situation of the entire intranet.

1. Check whether the temperature of the cat and router is very high in the afternoon, turn it off for a while if it is high, and try again, if it is good, the temperature is too high and the equipment is unstable;

2. In addition, there are too many connected users in the afternoon, and the network is congested.

If you can't connect all the time in the afternoon, it may be that someone has stolen your internet. If it can't be connected occasionally, it is because your cat's performance is not very good and it is too hot, and you need to cool it down.

When you encounter such a question, it is superfluous for you to come here to ask.

Immediately** broadband business to your home for testing.

The reasons why the internet is disconnected at night are as follows:

1. Internet time.

During the daytime, most people need to work outside the home, and there are few people at home. At this time, the network speed is naturally normal and smooth. But in the evening, especially between 9 and 12 o'clock, you will notice that the network is slowing down, because all the residents are home and are using the network at the same time.

In addition, the frequency band of the routers between them is the same, which will naturally cause a certain conflict in the signal, and it is normal for the network to slow down.

2. Network cable problems.

Network cable issues are also one of the most common causes of network slowdowns, but they are extremely easy to overlook. There are three types of network cable problems, which are specification problems, damage problems, and loose problems. All three of these problems will directly affect the speed of the network, causing signal instability.

3. Game software.

Unlike other software, game software not only has a large memory, but also requires a variety of support to run smoothly and smoothly.

Especially for those who have installed mobile broadband, you should feel that the network speed has dropped when playing games. This is because China Mobile has built an IDC computer room late, and some games also need to cross the network to access the servers of Unicom and Telecom. This can lead to lag and stuttering, which can make the gaming experience worse.

Hello, the network will be disconnected in the afternoon. Signal interference. Reason:

There may be strong sources of signal interference next to the router, such as microwave ovens, cordless**, magnets, high-voltage wires, etc. The wireless signals and strong magnetic fields emitted by these devices can seriously affect the WIF of the router...Countermeasures:

Turn off these devices, or install the router in a place with less interference. Router firmware issues. Reason:

If the router firmware version is too low, or the firmware and hardware do not match, it may also cause the router to work abnormally and cause the problem of unstable WiFi connection. Solution: Go to the official website of the router to find the latest firmware of the corresponding model, and follow the instructions to upgrade the router firmware.

Hope mine is helpful to you, thank you and have a great day!

Summary. Dear, hello, I'm glad to answer your question, the computer desktop is disconnected in the afternoon The solution is as follows: 1. The router has been attacked by DDS, and the other party knows the IP address of your router, so the DDS attack software is used on the computer to set up an attack on your router at a fixed time, which causes the router data traffic to be blocked, so that the network is blocked, or even interrupted, so the network is disconnected, when this time period passes, the software does not attack, and the network returns to normal.

In general, in this case, you can only press the restart of the router to restore the router to its factory value, then turn off the power, and re-plug the network cable, then plug it back in, and turn on the anti-DDS attack on the router, lock the IP and MAC address of the network card, you can effectively prevent this attack. 2. Even the system has been attacked, the Trojan has entered your computer, the Trojan has also set a time period, when the set time comes, the virus is automatically activated, and then specifically attacks the network port, which causes the network to be unable to enter the network card of the computer, and the network is naturally disconnected. Generally, in this case, you can only reboot the computer, press F8, enter the safe mode, in the safe mode, the full antivirus, restart the computer is OK.

The computer is fine in the morning, and the network is disconnected in the afternoon.

Mobile phones can be linked.

What do I need to do?

Dear, you can operate according to the above methods.

Turn it off, press F8 when it is turned on?

Dear, yes, press F8, enter safe mode, in safe mode, full antivirus, restart the computer is OK.

When there are frequent network disconnections, the first thing we need to determine is which is the internal network or the external network. Some friends may not know how to distinguish between intranet and extranet. To put it simply, the part that is routed to your computer belongs to the intranet, and the part of the remaining broadband modem and the operator's access line that comes in from outside belongs to the extranet.

How to determine which part is wrong, we can use the dos command that comes with the computer system to make a simple preliminary judgment.

1. Test the section of the computer to the routing first, that is, the intranet part is abnormal. Enter the system desktop, press the win+r key at the same time, the running window will appear, enter cmd and press enter.

2. The following DOS window appears, enter ipconfig, and then press enter, see what your routing gateway is, the routing gateway on my side is, different network gateways may be different.

3. Then enter ping -t, if your gateway is different from mine, you will have to replace it with your gateway, just pay attention to this. And then start sending and receiving packets like this, normally < 1ms with no disconnect in between. If it looks like the following, it means that the intranet is normal'。

4. Let's check the situation of the external network again. We can ping -t, why ping? Because it is an external network address, you can judge whether the external network is normal by observing the status of the computer connected to it.

Situations like the one below are normal.

5. What are the abnormal conditions? For example, a request timeout like the one below is not normal. The more frequent the outage, the more requests will time out, and the more dense they will be.

If the ping gateway is normal and the ping is frequently disconnected, it means that there is a problem with the external network, and if there is a problem with the packets returned by both addresses, it means that there is a problem with the internal network. Through the above method, you can quickly determine which part is wrong, so as to narrow down the search scope and reduce the workload.

We recommend that you take a look at the following solutions:

The first reason: this is the router has been attacked by DDS, and the BAI party knows the IP address of your router, so the DDS attack software is used on the computer to set up an attack on your router at a fixed time, which causes the router data traffic to be blocked, so that the network is blocked, and even interrupted, so the network is disconnected. In general, in this case, you can only press the restart of the router to restore the router to its factory value, then turn off the power, and re-plug the network cable, then plug it back in, and turn on the anti-DDS attack on the router, lock the IP and MAC address of the network card, you can effectively prevent this attack.

The second reason: the system has also been attacked, the Trojan has entered your computer, the Trojan has also set a time period, when the set time, the virus is automatically activated, and then specifically attacks the network port, which causes the network to be unable to enter the computer's network card, and the network is naturally disconnected. Generally, in this case, you can only reboot the computer, press F8, enter the safe mode, in the safe mode, use QQ butler to fully disinfect the virus, and some also use antivirus software, such as Kingsoft Antivirus, 360 antivirus software, antivirus, after the virus, restart the computer OK.
