The internet connection is slow, and the number of receptions keeps rising

Why is the Internet speed on the computer slow:

XP Win7 system will limit the speed of 20 by default, and we can easily remove this limitation, so that your Internet speed reaches 100%, and you can truly experience the feeling of surfing. Here's how: Start Menu Run Input".

OK Computer Configuration Administrative Template Network QoS Data Core Packet Scheduler Limit Reserved Bandwidth Attribute Enabled Change Bandwidth Limit to 0 Select Application OK Ok Ok.

What to do if the internet speed is slow:

At present, there is no real way to improve the speed of the Internet, and the best way is how to help users allocate bandwidth in a proper way.

First, first of all, understand that you are in the current network broadband state, operation method: open the main interface of Kingsoft Guard, enter [System Optimization], click "System Treasure Box", run "Network Speed Test", Kingsoft Guardian will calculate with accurate numbers, and recommend the current network situation for you which current network applications are suitable for you, such as **movies, online games, etc.

Second, if your network environment is a local area network, first check whether your computer is attacked by the ARP virus.

1. Enter the main interface of Kingsoft Guardian and enter [Real-time Protection].

2. Then click [System Protection] to turn on the ARP firewall.

Three. If there is no virus problem, check if there is a program that is taking up a lot of bandwidth and causing your computer to surf the Internet slowly.

1.Enter the main interface and enter [System Optimization];

2.Then click [Traffic Monitoring], and then disable access to the network for programs that occupy a large amount of traffic, or restrict the upload speed of the process. "

Follow my method to solve the problem, and ask me if it doesn't work.

Internet speed has little to do with mobile phones and computer software and hardware, so there are few mobile phones or computers that change because of network speed problems. The network speed is mainly related to the following factors: first, the transmission medium; The second is the transmission rate.

At present, the medium of the backbone network is optical fiber, which is the best medium at present, and most places have realized optical fiber to the home, so the medium of the backbone network is beyond question. The problem is that the quality of the indoor line is worth it**, although it has been fiber-to-the-home, but the network speed from the indoor to the terminal is 4m. In addition, the transmission rate is related to the service provider, but fortunately, the mobile network has entered the 4G era.

But you have to change the 4G card, the 4G phone. China ranks 98th in the world in terms of internet speed, why? I think most of the reasons are:

First, the line is aging, the quality is not high, the layout is unreasonable, and the key is that the "last mile" problem has not been solved; The second is that the maintenance service can not keep up, many service providers only know the charge, but less service quality improvement; Third, the coverage of cellular mobile networks is not very wide, and the signal in some areas is not strong, which affects the network speed; For example, 4G mobile phone 4G card, but where the 4G network is not covered, only 3G can be used; Fourth, from an objective point of view, China has a large number of users, and there are relatively many problems of network congestion, especially at 8-12 a.m. and 3-6 p.m. during the peak hours of Internet access. It is recommended that you avoid rush hour surfing.

Service providers repairing lines or maintaining systems can also cause slow internet speeds, so you can check with your service provider.

Leaving your phone uncleaned for a long time will also affect your internet speed.

Here are three pieces of advice:

Playing games, especially large games, is a drain on network resources. If you're short on internet speed, don't play.

Speed measurement with software is not very accurate, don't take the speed test results seriously.

The Internet speed mentioned in the service mark is a ** means and is for reference only.

Many netizens in a small-scale peer-to-peer Ethernet network composed of hubs may encounter such a situation: your network speed is fast and slow, when it is fast, it is like a big river going to the east, and when it is slow, it is like a snail on a tree. This is especially true when transferring a large number of files.

So why is this happening? Reasons why the network fluctuates quickly and slowly: Peer-to-peer networks generally use hubs as network connection devices.

The hub's ports are all bandwidth-sharing, i.e., only one pair of ports transmits data at a time. When a large number of computers are connected to a hub, the computers connected to the various ports compete with each other for bandwidth, making data transfer very inefficient because of the large number of collisions on the network that significantly reduce the available bandwidth of the network. The utilization limit of a peer-to-peer network is 40%, which means that when the data transfer rate of the entire network reaches 40% of the entire bandwidth, data can no longer be transmitted efficiently.

Some hub products have an LED indicator of network utilization, and if the LED with the sign "40%" is constantly on, it means that the network is saturated. Windows 2000 Server provides a network monitor that also shows the current state of the network. Workaround:

So how to solve the problem of fast and slow network? While reducing the number of computers on the network can solve this problem, it is a "one-size-fits-all" solution, and the only way to do this is to replace the network equipment. If the original network device is a 10m hub, and the network card is 10 100m adaptive, then the most economical way is to replace the hub with a 10 100m adaptive hub with the corresponding number of ports.

If the original computer network card is 10M, it is useless to replace the network equipment with a 100M hub, because the network bandwidth depends on the device with the smallest bandwidth. Due to the inherent drawbacks of hubs, the best way to address the fluctuation of peers is to replace the network equipment with an Ethernet switch. In fact, the ** of low-end switches is now almost the same as that of hubs.
