What is the reason for the sudden drop in the internet speed of the laptop, the sudden drop in the i

Let's say you're dialing up to ADSL.

1.Make sure that you are the only computer in your home that occupies the network, if there are other computers that are also using this network, confirm that he (she) does not use P2P technology software to ** things or watch movies, because P2P technology software has a great impact on Internet speed.

3.Although you say that no one rubs the Internet, but I still have to be verbose, take the ID card to the telecom to change the Internet password, this is a personal experience, I don't know whether the telecom is doing something or someone is rubbing the network, anyway, during that time my network is very slow at night, and it will be broken, I can't figure it out, and finally changed the Internet password and returned to normal.

Let's say you're cell broadband.

As CC Cecilia7270 said downstairs, users on the same LAN have grabbed everyone's bandwidth, and it is possible that someone in the network has been infected with the ARP virus, and then sent a spoofed message to your computer, of course, it is not excluded that someone deliberately uses software such as network executives to make trouble. A simple way to bind the IP address of the gateway to the MAC address, first, find a time when you are not expected to be attacked, such as early in the morning, to check what the MAC address of your gateway is (if it is under attack, the MAC address found out is also wrong) enter the command prompt, enter arp -d enter, and then enter ping to represent your gateway address), and then enter arp - A, press Enter, find the MAC address corresponding to your gateway address (format such as: 00-01-3S-45-56-FE) and write it down, use 360 Security Guard to bind, the method is to open "LAN Protection" in the "Trojan Firewall", and then manually enter the IP address and MAC address of your gateway in the "LAN Protection" of the "Traffic Firewall" for manual binding.

In addition, your cell is pulling optical fiber, which should not affect your network speed, because strictly speaking, it is two lines. That's all, I hope it helps.

Dial up directly with the computer to try if the network speed is abnormal.

The reasons may be as follows:

1. The wireless router is rubbed by people;

Solution: 1. The wireless router is rubbed on the network, change the password of the wireless router, the password is best not a pure number, to numbers, letters together, as long as you can remember, the more complex the better.

3. The computer background program secretly uploads the source file, brings up the task management interface, closes and kills the program that steals traffic in the background, and looks at it after a while, if the program is still resurrected, it can be uninstalled directly.

Internet speed limit Broadband bandwidth is not much in the first place, so there must not be much to divide your family, and there is no way to solve this, or you can only use a P2P terminator to intercept other people's Internet speed for your own use.

It's quite tragic to share it with others, so let's just order it.

1. Install Optimizer! , 2, Install 360!! 3. Please look for me.

Try to choose a time when there are fewer people, for example, many people are on the same road, and it is also very crowded.

Other situations. 1. There are viruses or Trojan horses

It doesn't have much to do with the system. It is possible that the network speed is normal during peak hours, and it is possible that the network speed is limited by others.

It has nothing to do with the computer, you check your internet speed and install a speed test software.

In the official ** test of telecommunications, dial 10000 if there is a problem
