When using laptops in work and life, have you ever encountered laptops that are very card, What is the cause of laptop card card? Many users don’t know what is causing the problem. Some technicians told us that it may be due to network problems, insufficient system resources, network cable problems, etc., which cause the network speed to slow down. The following editor will introduce to youthe problems that cause laptop computers What are the reasons for the card?
1. Causes of laptop lag - excessive use of firewalls
Excessive use of firewalls can also cause network speed to slow down. Needless to say, the solution is to uninstall unnecessary firewalls and only retain one function. Strong enough.
2. The cause of laptop card card-insufficient system resources
There may be too many applications loaded and running in the background. Please load the software appropriately or delete useless programs and files to free up resources to increase network speed. purpose.
3. Causes of laptop computer card problems - network problems
The server where the target website you want to connect to has insufficient bandwidth or is overloaded. The solution is very simple, please change the time period or change the target website.

4. Causes of laptop lag - network cable problems lead to slow network speed
One situation is that the network speed is very slow when you first start using it; the other situation is that the network speed is normal at first, but after a while, the network speed slows down. The latter situation is manifested on desktop computers It is very obvious, but when I checked it with my laptop, the network speed was normal. I have discovered this problem after many years of practice. The slowdown in network speed caused by network cables that are not made according to the correct standards is also related to the quality of the network card. Generally, the performance of the network card of desktop computers is not as good as that of laptops. Therefore, when troubleshooting using the swap method, use a laptop to check that the network speed is normal. It cannot be ruled out that the network cable is not made according to standards.
5. Causes of Laptop Card Cards - There are loops in the network that cause network speed to slow down
But in some more complex networks, there are often redundant backup lines. If they are connected accidentally, they will form a loop. For example, the network cable is connected from the network center to the computer room one, and then from the computer room one to the computer room two. Room.

6. Causes of laptop lag - a certain port in the network forms a bottleneck, causing the network speed to slow down
In fact, router WAN ports and LAN ports, switch ports, hub ports, server network cards, etc. may become network bottlenecks. When the network speed slows down, we can use network management software to view it during peak network usage hours The data traffic of routers, switches, and server ports; you can also use the Netstat command to count the data traffic of each port. Based on this, you can determine the location of the network data flow bottleneck and try to increase its bandwidth. There are many specific methods, such as changing the server network card to 100M or 1000M, and installing it. Multiple network cards, dividing multiple VLANs, changing router configurations to increase bandwidth, etc., can effectively alleviate network bottlenecks and maximize data transmission speeds.
7. Reasons for notebook computer card lag-broadcast storm caused by network equipment hardware failure, resulting in slow network speed
As the main means of discovering unknown devices, broadcast plays a very important role in the network. However, as the number of computers in the network increases, the number of broadcast packets will increase dramatically. When broadcast packets When the number 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 broadcast storms and paralyzing network communications.

8. Causes of laptop computer card lag--the impact of worm viruses causes slow network speed
Worms distributed through e-mail have an increasingly serious impact on network speed and are extremely harmful. This virus causes infected users to continuously send out emails whenever they are online. The virus selects random files on the user's personal computer. The document is attached to a random address in the user's address book and sent by email.Thousands of such spam emails are sometimes sent out in queues, and some are returned in batches and piled up on the server. This has resulted in significant congestion on some backbone Internet networks, significantly slowing down network speeds, and nearly paralyzing local area networks. Therefore, we must promptly upgrade the anti-virus software we use; our computers must also be upgraded in a timely manner, install system patches, uninstall unnecessary services, and close unnecessary ports to improve the security and reliability of the system.
The above is shared with you Causes of Laptop Cards , hope it helps you.
