Hello everyone, Lin Fei to answer the above questions, notebook computer stutter response slow how to deal with, notebook computer card many people do not know, now let's take a look!

1. When you use a laptop in your work life, have you ever encountered an unusual laptop card? What is the reason for the laptop card? Many users don't know why. Some technicians told us that it may be the network itself, insufficient system resources, network cable problems leading to slow network speed, and so on. The following editor introduces the reasons for the laptop card.

2. 1. Notebook computer card-the reason why excessive uses firewall

3. Excessive use of the firewall will also slow down the network speed. Needless to say, uninstalling unnecessary firewalls can only retain a powerful firewall.

4. II. The cause of formation of Notebook computer Card-insufficient system Resources

5. Too many applications may be loaded to run in the background. Please load the software reasonably or delete useless programs and files to release resources, so as to achieve the purpose of improving the speed of the network.

6. Third, the cause of notebook computer card-network problem.

7. The server you want to connect to the target website has insufficient bandwidth or is overloaded. The solution is simple. Please go to another time or change the target site.

8. Because of notebook computer card

Notebook computer card-the network cable problem causes the network speed to slow down

10. In one case, the network speed is very slow at the beginning of use; in the other case, the network speed is normal at the beginning, but after a period of time, the network speed slows down. The latter is obvious on desktops, but it is normal to check Internet speed with laptops. With regard to this problem, after years of practice, I have found that the slow network speed caused by the network cable not made in accordance with the correct standards is also related to the quality of the network card. In general, the network card performance of desktop computers is not as good as that of notebook computers. Therefore, when using the switching method to troubleshoot, using the laptop to check the normal network speed, we can not rule out the problem that the network cable is not made according to the standard.

Notebook card-there is caused by a loop in the network, which slows down the network

However, in some complex networks, there are often redundant spare lines, which will form a loop if they are inadvertently connected. For example, the network cable is connected to computer room 1 from the network center, and then to computer room 2 from computer room 1.

13. Reasons for notebook computer card

14 、 6. The reason for the laptop card-a port in the network forms a bottleneck, causing the network speed to slow down.

15. In fact, router WAN port and LAN port, switch port, hub port and server network card may all become network bottlenecks. When the network speed slows down, we can use network management software to view the data traffic of routers, switches and server ports during the peak hours of network usage. You can also use the Netstat command to count the data traffic of each port. Based on this, we can confirm the location of the bottleneck of network data flow and try to increase its bandwidth. There are many specific methods, such as changing the server network card to 100m or 1000m, installing multiple network cards, dividing multiple VLAN, changing the router configuration to increase bandwidth, and so on. It can effectively alleviate the network bottleneck and increase the data transmission speed to the limit.

16. 7. Due to the broadcast storm caused by the hardware failure of notebook computer card-network equipment, the network speed slows down.

17. As the main means of discovering unknown devices, broadcasting plays a very important role in the network. However, with the increase of the number of computers in the network, the number of broadcast packets will increase sharply. When the number of broadcast packets reaches 30%, the transmission efficiency of the network will decrease significantly. When the network card or network equipment is damaged, broadcast packets will be sent continuously, causing a broadcast storm and paralyzing network communication.

Notebook computer card

Notebook card-the worm causes the network speed to slow down.

20. Worms spread through e-mail have a more and more serious impact on network speed and do great harm. The virus causes infected users to keep sending e-mails as soon as they go online. The virus randomly selects files from the user's personal computer and attaches them to a random address in the user's computer address book to send e-mail. Hundreds of such spam messages are queued up and others are returned in batches and piled up on the server. As a result, some backbone Internet is obviously congested and the network speed is obviously slower, which makes the local area network almost paralyzed. Therefore, you must upgrade your antivirus software in time; computers should also upgrade and install system patches in time, uninstall unnecessary services, close unnecessary ports, and improve the security and reliability of the system.

21. The above is the notebook card business you share. I hope it will be helpful to you.

At the end of this article, I hope it will be helpful to you.
