Broadband has just been installed, why is the internet so slow?

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.

Why is your phone's Wi-Fi speed so slow?

There are a few common reasons why your broadband network 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;

2. Computer reasons such as low computer configuration 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 entrance line, change of the user-side line, etc.).

There are many reasons for this, the biggest of which is that the router needs to be restarted.

Why is your broadband at home getting slower and slower? Give you a trick to increase your internet speed by 50%.

Normal. Because there was a burst value when it was first connected. So it's faster. It's been a long time. And it came down.

There are many scenarios of network slowness, and further testing is necessary to find out the fault point before targeted troubleshooting, and the specific steps are as follows:

1. First of all, the stand-alone device is connected to the telecom optical modem and other equipment to ping the gateway or DNS server address of the telecom, and a numerical value is obtained;

2. Connect the router again (unplug the other network cables) and then ping;

3. Then connect to other computers and ping when it is in normal use;

Get 3 values, which is larger or has packet loss, it means that it is the problem of **, the first time is that the line of the telecommunications company is not good, the second time it means that there is a problem with the router, and the third time if it is abnormal, it means that there is a problem with the local area network.
