The internet is always intermittent and the speed is very unstable

The slow and unstable internet speed at home has finally been solved today.

Your question is not clear, whether you use a router or a cat to connect to a computer, if you use a router, see if the computer on other routers is using P2P software ** thing, or check to see if it is a LAN virus. Of course, the premise is that there is no problem with your network cable and the contact is good. If you only have a computer, call 10000 directly to ask the customer service of Telecom (if you use the network of Telecom), and they will send line personnel to deal with it for you.

The network is unstable, and there will be a network and there will be no network for a while, which can be caused by a variety of reasons. Possible causes and workarounds are:

1. Network connection problem: the network connection is not strong, which may lead to network instability, the solution is to check whether the network connection cable is plugged in, if the cable is damaged, you need to replace the new cable.

2. Network equipment problems: If the network equipment fails or ages, it may lead to network instability, and the solution is to replace the faulty or aging equipment.

3. Network interference problem: The wireless network may be interfered with, such as electromagnetic interference from other devices or building occlusion, etc., the solution is to try to adjust the location of the wireless router or use a stronger signal.

4. Network congestion: If the network traffic is too large or the network is congested, it may lead to network instability, and the solution is to try to avoid using the network during peak hours, or contact the network operator to increase the network bandwidth.

5. Operating system problems: If there are vulnerabilities or viruses in the computer's operating system, which may lead to network instability, the solution is to install anti-virus software and firewalls, and update the operating system patches in time. <>

The network is intermittent and unstable, which may be caused by some reasons, and the following are some reasons and solutions:

If the network cable is aging or the quality is problematic, replace the network cable to ensure the quality of network transmission;

Check whether the crystal head of the network cable is loose or damaged, and it is recommended to replace it;

Viruses in LAN computers are recommended to be sanitized with antivirus software to clearly understand the factors affecting the network;

Check if your computer system is running multiple firewalls that block the network and shut it down;

Reinstall the computer and open the browser to test the network status.

If none of the above methods can be solved, it is recommended to contact the network provider to check the signal source problem of the network.

A network is made up of nodes and wires that represent objects and their interconnections. Mathematically, a network is a type of graph, and it is generally considered to refer specifically to a weighted graph. In addition to the mathematical definition, a network has a specific physical meaning, that is, a network is a model abstracted from some kind of practical problem of the same type.

In the field of computer, the network is a virtual platform for information transmission, reception and sharing, through which the information of various points, surfaces and bodies is linked together, so as to realize the sharing of these resources. The Internet is the most important invention in the history of human development, which has improved the development of science and technology and human society.

What to do if the network is unstable, I always feel that the network connection is unstable, the problem is here, quickly check it.

1.Your network environment?? A cat? Or a cat a router 2Have you ever tried to connect your computer to a friend's cable? Is it OK?

If it doesn't work, try reinstalling the network card driver. Or install a separate network card to see.

If it's OK, it means that your computer including the network card is fine, and the problem is back to your network. See 33Replace a cat to try? If it doesn't work, call ** to notify the ISP to deal with it.

Hope it helps.

I've also encountered this problem,In order to solve it properly,You update the network card driver first,In addition, I heard that now 360 and QQ housekeeper will affect the network after the update,If you will, you will reinstall the system,Dial and try without installing antivirus software,Take a look at it in ping,I can be sure that it is a problem with telecommunications,We used to be like this,As soon as you connect ** it will fall,Later on-door maintenance of wires,Directly tell us that the network in our area is like this,Telecom communication equipment is aging,Often drop packets, can't solve it. You can only use it.

What age is it now, and it is still used 2m, it must be slow, check step by step.

The voice splitter is not broken.

The cat is not broken.

There is no connection to the router

After the broadband is connected, ping the external network server address such as ping -t to see if there is any packet loss, if there is, there must be a problem with the line on the network operator's side! It is recommended to call the operator's customer service for repair! Under normal circumstances, there is not much problem with the network card, and if you eliminate the method, you can only get a notebook to try!

Also, the rate of 2m can be measured with 360 and 400kb s should not be telecomic, right?

Black Panther Network's professional cracks the wifi wireless router password, and guides the whole process to decipher'Can't crack it'Free returns.

Answer 1: After a computer in the network is poisoned, the network is blocked due to frequent data packets, and other computer networks in the network will be intermittent. 2. Look at the router to see if there are any big electrical appliances next to the router, because this is also a signal that may trigger Wi-Fi. 3. The aging of the router or switch transformer leads to the unstable operation of the internal components of the router, and the router is getting better and better, and the quality is not as reliable as before.

4. And then there is a lot of software on the computer will occupy the network channel, sometimes I don't know if I don't pay attention to it, so I can close it.

Anyway, go directly to the computer city to solve it.

IP address conflicts are most likely ARP spoofing, and some rate-limiting software uses this technique. I don't know about foreigners, but there are a lot of people who use this kind of software in some communities or shared networks in China. If you don't have the quality, this kind of software can also completely cut off the flow of others, that is, the network.

According to what you said, first, the landlord can solve the problem of disconnection, and you receive a notification of an IP address attack, then it is possible that he used this software. Second, the speed of the Internet is sometimes fast and slow, and the difference is very large, and if you troubleshoot the carrier, it is very likely that someone is using similar software to limit your Internet speed.

Since it is ARP spoofing, it is not other speed limit measures, so it is easy to solve. Workaround:

1. Use "Anti-P2P Terminator".

2. Install the ARP firewall.

3. Bind the IP address to the MAC

The specific method is very simple, just search on the Internet! Good luck.

The wooden structure has little effect on the signal, see if there is a metal structure or a cement structure on your transmission route that will affect this. For example, sandwich walls or wooden floors generally have aluminum foil moisture-proof, so that the signal is attenuated quite strongly.

1: The fast network speed of the router does not mean that it is stable, just like the TPLink network speed is fast but the network is disconnected, and the dlink network speed is average but it is okay to open all year round. (Personal experience is not an advertisement).

2: If there is an IP address conflict, simply turn off DHCP and use a static IP once and for all. It turns out that DHCP is sometimes very brainless, and it is very easy to conflict with the fact that you only have to assign your own address, regardless of the network situation, such as your roommate's own IP designation.

3: What is the model of the wireless network card of the notebook, what system do you have, and if your computer is used to sleep or standby and then turn on, is the network speed not good? This requires you to log out of the system before entering.

Generally, the disconnection may be caused by the long distance, or the problem that the wireless routing power is not large enough, or it may be caused by too many people using wireless.
