Why is my internet speed slow during the day and fast after 12pm?

Other reasons for slow internet speeds are as follows:

1.Virus Trojan horses cause slow network speeds.

3.Multiple computers share the Internet, and the computer in the shared network may have ARP virus, the solution is to find the source of the attack and use 360 to kill the computer (solution point 6).

4.Aging broadband lines, or broken or poor quality routers (board quality), resulting in slower internet speeds.

5.If the computer and ** are in different network environments, such as the access between Netcom users and telecommunications**, the network speed will also slow down.

6.The server is very poor, and the network speed is slow due to limited bandwidth.

7.System efficiency or hardware issues.

There are two scenarios.

One: you have a lot of broadband users during the day, and you use ADSL Internet access, ADSL Internet access is a dynamic IP Internet access, which means that under a large metropolitan area network, you and others are public bandwidth, for example, you apply for 2M bandwidth, but sometimes you can reach 250K, but sometimes only 120K, which is very normal, and the bandwidth you can occupy will decline when the telecom business is busy.

Two: It is that someone may attack you. Of course, if you're using it alone, you won't have that problem.

It's actually like internet speed.

There are many reasons for problems, such as machine poisoning, network cables, and weather conditions, all of which may cause network failures.

If you want to find out your current situation, it is best to consult your local network service provider, I believe they will give you a satisfactory answer.

There are several reasons why the internet speed slows down at 9 p.m., and the general analysis is as follows:

Cause. 1. Community broadband has reached its peak of Internet access.

The use of community broadband (LAN), due to bandwidth sharing, once the number of Internet users in the community is large, the network speed will become very slow during the peak period of Internet access, so 9 o'clock in the evening is the peak period of Internet access, and the traffic may cause the network speed to be slow;

Reason 2: Someone rubbed the net.

Generally, the computer with wired Internet access will not encounter this situation, but with the popularity of notebooks, more and more people use wireless as a way to network, but wireless has a big disadvantage that it is easy to be rubbed against the network, once it is rubbed against the network, their network speed will naturally slow down, after all, the bandwidth is limited, others use more, and there is less for themselves.

Solution: When using wireless Internet access, you must set a wireless password, and it is best to change the wireless password regularly to prevent rubbing the network to the greatest extent. Computer Virus:

Whenever there's a problem with your computer, it's a good idea to look for it (although in many cases it's not caused by a backup virus). Viruses are the product of following computers and are specifically used for sabotage, and many people's first reaction when the Internet slows down is poisoning, although sometimes they are wronged. Workaround:

Perform a comprehensive scan, preferably in safe mode, for better results.

Reason 3: The network connection line may be aging.

Home broadband generally uses the first line as the connection method, but with the long-term use, the first line will inevitably wear out, oxidize or age, which will affect the quality of the Internet, and the slow down of the network speed is also one of the situations.

Solution: Replace the aging line, it is best to overhaul the line every once in a while.

Workaround: It is recommended to use an ARP firewall along with a P2P terminator to see the current user traffic and throttle it.
