Downloading an episode of video suddenly slowed down. For example, downloading the first episode is very fast, and when downloading the second episode, it is suddenly only a few kilos per second. It's always been like this, and Bandwidth size of broadband access

If the access bandwidth is 2M, but the number of users is more than 2, and some people watch videos, movies and download software such as Thunder, bps, Express, Electric Furnace and Cyclone, it will definitely lead to slow Internet access.

Is the bandwidth set on the router?

Such as IP bandwidth control, the set bandwidth is too small and the network speed is very slow. After removing all the settings on the router, does the network speed return to normal?

2M broadband, the maximum download speed is 256KB/S, which is generally lossy and basically difficult to reach the standard value.

Are computers in the LAN poisoned (such as worms)

If there is computer poisoning in the LAN, you can install anti-virus software on the computer, upgrade the anti-virus software to the latest version, and thoroughly kill the computer. At the same time, computers should upgrade and install system patches in time, uninstall unnecessary services, and close unnecessary ports to improve the security and reliability of the system.

The network cable problem caused the network speed to slow down.

Whether the network speed is normal without going through the router when a single computer dials up the Internet. If the stand-alone computer is still slow when surfing the Internet, it may be a problem with the line.

Insufficient system resources (such as high CPU utilization)

You may have too many applications loaded to run in the background. Please load the software reasonably or delete useless programs and files to release resources, so as to improve the network speed. For example, the CPU is very busy, which will directly affect the network and computer speed.

How to look at CPU utilization? You can use the shortcut key CTRL+ALT+DEL.

Problems with the network itself

The target website you want to connect to is located on a server with insufficient bandwidth or heavy load. The solution is simple, please change the time or change the target website.

This system has been used for too long.

The network speed suddenly slows down after a long boot, so you may wish to restart it to see if you can solve the problem. The boot time is long, especially when the weather is hot, the notebook is not well cooled, the CPU temperature is too high, and the overall performance of the system is degraded.

Excessive use of firewall

Excessive use of firewalls will also slow down the network speed. For example, some antivirus software packages have their own firewall function. The solution is not to uninstall unnecessary firewalls, but to keep only one powerful enough.
