The broadband speed slowed down for no reason, but the data packets were sent normally at more than

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.

1.If the temperature of the router or cat is too high, lower the temperature of your router or cat.

2.The problem of the network cable, I helped several netizens yesterday are due to the problem of the network cable, which leads to unstable Internet access. The landlord had time to try it out with a new network cable.

2.Delete the network card driver and reinstall it.

3.Please double-check to see if your roommates have enabled speed limiting software such as P2P. If it is turned on, please turn on the LAN defense in 360 and turn on ARP defense. (Anyway, I often use P2P to limit my roommate's network).

The problem is up. Please bind your IP to your MAC address. Here's how: Start - Run.

ARP S host address MAC address.

Basically, the hardware and software aspects are involved, if it can't help you, I'm sorry to learn lightly.

Hello! What kind of packet is it, and how big is it?

If there is a network fault, check the network cable connection and IP settings, or restart the relevant network devices (routers, switches, etc.).
