After the computer has been online for a while, the network suddenly becomes very slow

1. Poisoning 2. Too much software.

3. Software Conflicts.

Fourth, the system has not been installed for a long time.

Fifth, the hard disk has been working for a long time, and there are problems such as speed at high temperature.

6. Bandwidth (fast speed without Internet access).

7. Memory aging.

8. Sorting out the internal garbage of the computer.

There are a number of other reasons.

Reason 1: The fault of local viruses and Trojans.

This is the answer that many netizens think of for the first time. Yes, infection with certain viruses and Trojans can indeed cause slow internet speeds. However, how many netizens will verify it?

Verification Step 1: Use anti-virus software to check for viruses thoroughly. This is the easiest way to do this, but it doesn't always work out.

Verification Step 2: Observe the CPU operation and network conditions. If the CPU is running non-stop for no reason, and the network connection is constant, it is possible that a virus Trojan is the cause.

Verify Step 3: Dos commands. Ping under DOS to see how responsive the network is.

Cause 2: Server issues.

Surfing the Internet has to go through many servers to reach your destination. Therefore, the server directly affects the user's network speed. Network congestion can also slow down internet speeds.

Cause 3: Network viruses targeting the server.

Network viruses that target servers tend to slow down or bring down networks. However, it is not the user's business to solve this problem.

Cause 4: Local system issues.

The system takes a long time and often fails. If the internet speed slows down suddenly long after the device is turned on, you may want to restart it to see if it solves the problem. Sometimes, it is even necessary to reinstall the system to solve the problem.

Reason 5: The CPU is busy working.

The CPU is busy working and will directly affect the network and computer speed. So it's necessary to check how your CPU is working when the internet is slow.

Is there a fixed IP? If so, it is likely that the resource has been stolen. Do you have a firewall? What is the setting level?

Usually, fixed IPs are easy to be implanted with Trojans and are treated as "broilers". Even if the system is reinstalled, it will be re-implanted in the Trojan soon (because the IP has not changed). Or maybe it's because the individual software you're using now is bundled with a Trojan horse, and every time you reinstall the system, you reinstall that software, and you also install the Trojan.

Solution: Reinstall the system in a clean state (no other software is installed, except for the driver), install the firewall and Trojan scanning software. Note: Do not surf the Internet without firewalls and Trojan scanning software.

I don't know what the hell you're asking ... Slow Internet access: 1 Is it too long to buy the computer 2 Antivirus 3 Cleaning 4 Wireless router plus no password 5 Is there too many web pages.

1. Delete unnecessary files. When using a computer, it is important to know that the files on the desktop and the C drive will directly affect the speed of the computer. Try to put as few things and files as possible in the desktop and C drive of the computer, and you can move them to other disks to reduce the memory of the desktop and C drive.

Don't forget, the station also needs to be cleaned regularly.

2. Expand memory. Some computers themselves have low configurations and less memory, due to too many files installed in the computer, the computer will be slower and slower. This data exchange is prone to full load, that is, insufficient memory, at this time, the most effective is to buy a memory module to expand the memory, expand the memory of the computer, not only to speed up the running speed of the computer, but also to use more useful software.

3. Antivirus. The computer must install anti-virus software, regularly clean up the garbage of the computer, and can **360 Guard, Kingsoft Guardian and other anti-virus software. When the computer responds slowly, we can turn on 360 Guard for antivirus, which is very convenient, you can clean up the cache garbage generated when surfing the Internet with one click, these cache files have been piled up for many years and are very space-consuming, so you should develop a good habit and clean up the garbage regularly.

4. Reinstall the system. When deleting files, anti-virus can not improve the slow response of the computer, then you must go to a professional computer store or buy a reinstallation disk by yourself, reinstall the computer system, reinstall the system can effectively improve the slow response of the computer, but it must be noted that important files should be left before reinstalling the system, just in case.
