Why is the Internet speed at home very good, and the death of the card is still stuck, please help m

Causes of slow internet speed and ways to improve internet speed:1If your computer is infected with certain viruses or Trojans, it will cause your internet connection to be slow.

First, use anti-virus software to check the virus comprehensively; Then check the CPU operation and network conditions, if the CPU does not stop running for no reason, and the network connection is not interrupted, it may be caused by a virus Trojan. 2.A computer has to go through many servers to reach its destination, so the server directly affects the speed of the computer's network.

3.If your system is used for a long time, there will often be problems, such as a sudden slowdown in the network speed after a long time of booting, you can restart it to see if it can solve the problem. Being busy with work can directly affect the speed of your network and computer.

To keep it good for heat dissipation. 5. The influence of worms causes the network speed to slow down. Worms distributed via e-mail have an increasingly serious impact on network speed and are extremely harmful.

This virus causes the infected user to send e-mails as soon as they go online, and the virus selects random documents from the user's personal computer to attach them to a random address in the user's address book to send e-mails. Hundreds or thousands of such spam emails are sent out in queues, or they are returned in batches and piled up on servers. As a result, some backbone Internet networks are obviously congested, and the network speed is significantly slowed down, so that the local area network is nearly paralyzed.

Therefore, it is necessary to upgrade the antivirus software used in a timely manner; The computer system should also be upgraded in a timely manner, install system patches, uninstall unnecessary services, and close unnecessary ports to improve the security and stability of the system. 6. Don't install too much. Firewall.

Excessive use of firewalls can also lead to slow down network speeds, so uninstall unnecessary firewalls and keep only one powerful one. 7.The system resources are insufficient.

There may be too many applications running in the background, so it is necessary to load the software reasonably or delete useless programs and files to achieve the effect of improving the network speed. It's a good idea to kill the virus before shutting it down, because the virus is active all the time, and once infected, it will greatly affect the speed of the Internet. 8.

Use good antivirus software. Antivirus software should be upgraded every day, don't be afraid of trouble. 9.

**An internet speed monitoring and control software, such as P2P network terminator, Jusheng network management and cyber enforcement officer, etc., can detect whether your bandwidth is throttled or stolen by others, and you can also set the internet speed.

Slow internet speeds are generally caused by the following reasons.

1.Problems with your operating system (including missing files, viruses, Trojans, too much disk fragmentation, etc.).

2.Problems with your browser (including missing files and being hijacked by rogue software).

3.There is a problem with your network hardware (including routers, network cards, network cables, etc., such as hardware failure, magnetic interference, etc.).

4.Problems with your network provider (including the non-telecom network you choose such as China Unicom Netcom, etc., their bandwidth is limited, generally telling you that you are 2M, but sometimes only tens of k, the network is particularly unstable when it is busy, and it is only stable in the middle of the night).

5.Weather reasons, including thunder and lightning, etc.

6.Some operating systems have a limit on the number of network connections (for example, the default number of connections for XP is 10) and hardware drivers are not equal.

7.Improper settings of firewall anti-virus software (may restrict certain ports, may set too many access rules, etc.).

8.The computer configuration is too low, and the software starts too much, resulting in a severe shortage of system resources.

3.The amount of servers you want to access or the game servers you want to log in to is too large, resulting in overwhelmed servers, reduced efficiency, etc.

4.There is a problem with the ** program design you want to access, and there is a problem with the program design of the game server, resulting in too many bugs, which affects your normal browsing or playing games, making you feel that the network speed is slow.

5.The server you log in to is Netcom, and you are a telecom network, there is a difference in speed when accessing each other, this is quite obvious when playing games, when you access the Netcom server in the telecom network, it is painful and very slow.

That's probably it, I'll try to talk about it in a popular way, so that you can understand it well, you can use the elimination method, try it one by one, find the right medicine for the problem, and solve the problem quickly.

What should I do if the wifi speed is very slow?

Reason 1: The fault of local viruses and Trojans (I guess you are not the reason) 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. Reason 2: Server Problems Internet access has to go through many servers to reach the destination.

Therefore, the server directly affects the user's network speed. Network congestion can also slow down internet speeds. Reason three:

Network Viruses Targeting Servers 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. Reason 4:

Local System Problems Systems tend to fail over a long period of time. 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, which will directly affect the network and computer speed. Therefore, it is necessary to check the CPU operation when the network speed is slow.

The Internet mobile phone at home is always stuck, and after careful checking, I finally found the reason.

1. Clear the DNS cache. This is mainly used in some ** situations that cannot be opened.

First, press the windows + r keys at the same time, enter cmd in the pop-up window, and press enter.

In the pop-up command prompt, enter ipconfig flushdns and press Enter.

2. Reset the winsock directory, enter netsh winsock reset in the command prompt, and press enter. After the reset is successful, restart the computer. This command is very easy to use.

If the broadband network speed is slow, there may be one of the following reasons:

The server accessed has a narrow bandwidth or a busy server;

Reasons for the computer, such as low computer configuration or weak system processing power;

It may be a virus or Trojan horse that causes slow Internet speed;

Using a router to share the Internet leads to slow internet speeds;

The modem device is not working well;

Line reasons (such as long lines, noisy lines, poor quality of inlet lines, changes to the user's lines, etc.).

If the above instructions still cannot be solved, you can contact the local Unicom customer service for processing.

The Internet mobile phone at home is always stuck, and after careful checking, I finally found the reason.

Reasons for the slow vertical track speed of broadband networks:

1. If the bandwidth of the ** server is narrow or the server is busy, you can try to change the time period to access or visit other network tracking stations to determine whether this problem is caused;

Second, such as computer configuration.

Computer reasons such as low or weak system processing power;

4. The use of routers to share the Internet leads to slow network speed;

5. If the modem device is unstable, it is recommended that you replace the modem device for testing;

6. Line reasons (such as long line, noisy line, poor quality of the home line, change of the user-side line, etc.).

If this is not the case, you can contact the local customer service for feedback.

First of all, your machine sucks, isn't it? The configuration does not meet the requirements 2 Is your game ** in full storage? You can clean up the next 3 or you open too much of the stuff.

Try the key 4 The graphics card is not good to change the graphics card 5 The memory is small?

This could be because there's an isolator that affects the network at a short distance, or it's because your computer's buffer isn't good!

Good network speed does not mean that the configuration is high, and the network speed is low and the network speed is high, or there is a problem with the system, try to reinstall.

There are several reasons why broadband internet is slow:

1. If the bandwidth of the ** server is narrow or the server is busy, you can try to change the time period to access or access other** to determine whether this problem is caused; Sail stockings.

2. Computer reasons such as low computer configuration or weak system processing power;

Fourth, the use of routers to share the upper code state network will also lead to slow network speed;

5. If the modem device is unstable, it is recommended that you replace the modem device for testing;

6. Line reasons (such as long line, noisy line, poor quality of the entrance line, change of the user-side line, etc.).

If this is not the case, you can contact the local customer service for feedback.

If the problem of the virus is ruled out, then it may be a problem with the weather, because if the machine is overheated, it will reduce the frequency to achieve the purpose of cooling the source of the game, the speed of the machine is slowed down, and the speed of your opening of the web page will be slower, and it may be that the network is not very stable in maintenance, if this is the case, it will be good to laugh at the oak after a few days!
