The Internet is sometimes fast and sometimes slow, what is the situation?

You first check whether the crystal plug of the network cable is loose, click on the computer, then open the device manager, find the network adapter point to deactivate, and then start it, maybe it's fine. If not, don't be angry! Sit down, have a cup of tea, and cheer up in the hot summer, the temperature is very high, don't you feel hot?

You put me here and don't care about us; The temperature of my chip is above 40 degrees, the temperature of the hard disk is higher than 45 degrees, and the temperature of the network card is more than 80 degrees; Can you work in such an environment? You still have a fan or an air conditioner or something, do you mind my business? Our Equipment (Device means:

Cats, routers, network switches, Hubble, computers, etc.) too, feel hot and can't work for you anymore; You can't go to the Internet, you look for masters in the north and south, don't cool me down, you can't find anyone (or replace cats, routers, etc.), because our brothers have the same temper, if you don't cool us down, we will strike! You may wish to take a look at the following methods, and use measures that you feel are acceptable to reduce the temperature of my (equipment) working environment, I promise: continue to serve your elderly.

A: Users who often surf the Internet for up to half a year should open the shell of the device after the power is off and clean up the dust inside the device. b: Place the equipment in a safe place for people, open the lid of the equipment, use air convection to strengthen contact with the air, and naturally dissipate heat;

c: Install a micro fan to the equipment to increase the convection of air and force heat dissipation;

D: If you are doing IT, I suggest that you install a heat sink on the heating part of the device after disconnecting the power supply.

e: After the equipment is disconnected from the power supply, use a 3mm drill bit to drill many holes up and down the equipment to strengthen the air convection flow and improve the heat dissipation conditions;

f: To ventilate and dry the equipment, it is best to make an insulated heat dissipation bracket (there are also notebooks on the market) to support the equipment for natural heat dissipation;

H: Let the adsl cat sync first: power off the cat and restart it.

i: The software settings are reasonable, so that 3 do not install: do not install informal software, do not install P2P (occupy resources) software, and do not install infrequently used software.

Turn off all unnecessary network connections, such as Thunderbolt BT Donkey, etc.;

j: Optimize the network Personally, it is recommended to use some gadgets such as Super Rabbit, Optimization Master or 360, etc.K: The computer should install at least one effective and genuine antivirus software l: Network card problem: The network card has appropriate bandwidth and stable operation.

We are now in the era of networking, where every household has a network and there is a public network in various public places. Generally, the installation of optical fiber or broadband network in people's homes is from 1m to 100m. When I surf the Internet, some people will say, I spent so much money to install the Internet, why is the Internet speed so slow?

In fact, the slow network is not necessarily a problem of the provider, it may be a problem that you have not set up, so let's understand what the problems are.

1. Minimum network bandwidth.

This is the most important factor, that is, netizens often say that the broadband is not enough. Similarly**, if the bandwidth is high, the access speed will be significantly faster.

The bandwidth of the network includes two aspects: the bandwidth of the server and the bandwidth of the user, and the docking point refers to the exit end and the import end (such as the docking point of telecommunications to Netcom).

2. DNS resolution speed.

DNS resolution is the resolution from a domain name to an IP address. People are accustomed to memorizing domain names, but machines only recognize each other's IP addresses, and domain names and IP addresses correspond to each other, and the conversion between them is called domain name resolution, and domain name resolution needs to be completed by a dedicated domain name resolution server.

DNS resolution includes the number of reciprocating resolutions and the time spent on each resolution, and the product of the two is the total time spent on DNS resolution. Many people ignore the factor of DNS resolution, but it is also very important for the resolution speed.

3. Server and client hardware configuration.

In the same network environment, the computing power of the dual-core server must be stronger. In the same client, in the same network environment, if you use an Intel i7 processor and an i3 processor to open the same page, the speed must be different.

4. Server software.

On the server side, the amount of software installed and whether it is running stably will affect the server environment, which in turn will affect the network speed. For example, if the server is equipped with a software firewall, the network speed will be affected.

5. Page Content.

If a page contains a large number of unprocessed pages that are large, it will cause it to open slower. Others, such as flash and video files, will affect the access speed.

At the same time, redundancy is also a factor that slows things down. The webmaster needs to optimize as much as possible before returning to the front, and use the least ** to achieve the best effect.

This has a lot to do with the router, including the ridge area of your house. In addition, the side chain gives you a certain connection to the layout of the network of your home, if the house is very large, in fact, I recommend that you choose multiple routers for networking.

You take a look and see if you can fix it.
