What s going on with the internet speed suddenly becoming super slow? Computer reasons?

Your network is a local area network, when everyone uses it, your network speed will be slowed down, and when everyone is not using it, your network speed will be fast, and our dormitory is like that; It's also possible that your Thunderbolt is turned on, and it secretly uploads your computer's data, limiting its upload speed and improving the network speed.

Also, clean up your system disk with a system optimization master, which can also provide network speed.

You open your task manager and see if there are any redundant processes that will definitely cause your internet connection to be slow, and then turn off the ones you don't use. You can also use the network speed-up, very good, non-toxic, green product, hehe!

Sky, Dott has it, I recommend Dot, because I have a lot of the same software, all of which are on Dot, and nothing else, hehe. Finally, consider whether there is a virus.,I think the landlord usually pays attention.,Generally, it won't.,There's arp.,It will cause you to not get up.,360There are Trojan horse settings.,You can effectively delete it.。

This ** is very good, there are many programs and software that we commonly use in it, which is very convenient.

There are at least a few possibilities for this.

I guess the biggest one is probably a problem with telecommunications.

I'm here for a month, and there are always 1-2 times that your kind of problem usually lasts no more than 1 hour.

There are many possibilities.

1.Poisoned.

2.Your network may be compromised or conflicted.

3.There is a local problem with the network in your home area.

Enter the msconfig command in the runtime, close a few startup items, and clean up the temporary files in the browser.

1...Check the startup items with 360 Security Guard, it may be that there are too many junk plugins. Now the P2P plugin is very blood-sucking. Optimize it.

2...Restore the system to 3 computers, and the problem is the line.

You turn off the router and restart it or reinstall the NIC driver to try it. It's better to reload. It's not easy to reinstall it, it's a broadband problem.

It's great to use Windows Optimizer!

There are always times when it is very slow, and there are many reasons: your system, line interference, unstable equipment, full line traffic, access to the equipment in the computer room, and then go out of the line, equipment... To the service provider's network, line, server traffic, resource usage, etc., because these are connected in series, any one of the problems, you may encounter full, inaccessible situation.

Three reasons:

1. Restrictions made by service providers.

Workaround: Contact the service provider.

2. Someone rubbed the net.

3. Your computer is running a program that takes up a lot of bandwidth.

Solution: Check in the task manager to see if there is Thunderbolt, BT or other P2P software running, if so, turn it off and remove it from the startup item.

The network cable or the hardware related to surfing the Internet is aging.

If it is uninstalled, it may be that your computer has a virus.

Reason 1: Local viruses and Trojan horses are at fault.

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 in the layer to reach the 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 after a long time of booting up, 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 when the network speed is slow, it is also necessary to check the CPU operation.

This solution is applicable to XP Vista Win7 system.

Problem Description]:

Test your broadband speed.

Easy Steps]:

Open [360 Security Manager] - [Function Collection] - [360 Broadband Network Speed Test] [Solution]:

Turn on the 360 broadband speed test.

Sudden slowdown,?? Then you should kill the virus. Remove the system startup items that you don't use, and disable the services you don't use. Remove the software you don't need and defragment the disk.

It may be a problem with the network bandwidth, but it is often impossible to connect, and I guess someone is attacking, possibly within the local area network.

If there are still abnormalities, you can also contact me to help you check it.

Points: Start, Run, Enter.

msconfig

Removed the normal boot program and rising in addition to the system

other programs.

If it doesn't work again, install a Trojan software. If it doesn't work again, redo the system.

In view of what you said, the situation can be divided into several kinds to judge, one is that the network cable is aging, the network speed is not as fast as before (solution: call ** to call the network provider to change the line), the second is the machine system problem (the solution is to reload the system, the system is rebuilt, and all the disks are formatted), and the problem has to be checked step by step to check the problem, believe me, because I am engaged in broadband maintenance.

Because your computer has too much P2P software (Thunderbolt, IPTV, Q broadcast, etc.), these software will drag down the bandwidth a lot. You try to delete all of these software, and then redial the number!

Upgrade your browser, change to the version, close the startup program if it's still slow, and change the system if it doesn't. Install the Lite version of the XP system. Absolutely OK

If there is no problem with the computer configuration, there are three reasons for the network speed to be too slow, one is the problem of the computer itself, comprehensive antivirus, use 360 guard to clean up malicious plug-ins, clean up system junk files; the second is the system problem, reinstall the system to solve; The third is the network or ADSL equipment problem, directly call the broadband operator's ** repair.

1. Open the case, remove the dust, check the heat dissipation of the CPU and graphics card, and oil the fan.

2. Antivirus. Unplug the network connection, turn off System Restore, and use the latest version of antivirus software to kill the virus in safe mode, and it is best to change to another antivirus software to kill again.

3. Clean up and defragment the disk.

1. In the window of my computer, right-click the drive letter you want to clean up - "Properties" - "Clean Disk" - check the files you want to delete - OK - Yes.

2. Clear the temporary file, start-run-enter %temp%-OK.

3. Clean up the registry and junk files with Optimizer or Super Bunny.

4. Close some startup programs, start-run-msconfig---start, in addition to anti-virus software, input methods can be turned off in general.

5. Delete unused program software.

4. Upgrade the graphics card and network card driver.

5. Increase physical memory, replace it with high-quality memory, and set up virtual memory reasonably.

1. To play games, the virtual memory can be set to be larger, the minimum value is multiple of the physical memory, and the maximum value is 2-3 times of the physical memory. No matter how big it is, it takes up too much space on your hard drive.

2. The method of setting virtual memory is: right-click on my computer - Properties - Advanced - Performance Settings - Advanced - Virtual memory change - Select the partition where the virtual memory (page file) is stored in the drive list - Custom size - Set the value in the "Initial Size" and "Maximum", then click the "Settings" button, and finally click the "OK" button to exit.

3. The partition where the virtual memory (page file) is stored must have enough space, and the hard disk resources are insufficient, resulting in insufficient virtual memory.

6. Optimize your computer with Optimizer or Super Bunny.

It's possible that the right virus is right, kill and see.

First, it may be a problem with the speed of the Internet.

Second, it may be that someone in the LAN has placed something.

Three, it may be poisoned.

Fourth, the problem of the network card (the probability is very small).

If you are surfing the Internet at home, it means that there are too many connections to the same router, that is, many of your neighbors are surfing the Internet at the same time, so it will slow down.
