Why is the internet sometimes fast and sometimes slow when I get off something?

Method steps.

There are mainly the following reasons:

1. Network operator issues.

At present, home networks use shared bandwidth, and your network speed can be guaranteed during off-peak periods, but during peak periods, you can't guarantee normal speeds. Especially at 8-10 o'clock in the evening, everyone likes to go online and watch movies after eating, and the Internet speed will be quite slow at this time.

2 Router Causes.

If the router works for too long, the network status is unstable or even disconnected. At this time, you only need to power off, restart the router, and wait for a while to recover. For such situations, you should develop good Internet habits and turn off the power of the router in time when you don't need to go online.

3 modem (cat) causes.

For users who use ADSL to access the Internet, the modem (cat) working for a long time will also lead to no problems with the network or even network disconnection, which can be restored after power failure and restart. The solution is the same as the router solution, develop good Internet habits, and turn off the power in time when not in use.

4. NIC performance.

With the continuous upgrade of network bandwidth, the requirements for NIC performance will become higher and higher, and if the NIC performance is too low, it will also cause network instability.

5. Wireless stability.

With the development of wireless technology, laptops, smartphones, ipads, and even desktop computers can be connected to the network through wireless technology.

6Multiple computers share a single network.

When multiple computers share the same network, one computer will have a high speed of data, and the other computer will have an unstable network, especially if the bandwidth is relatively small. This problem can be solved by routing rate limiting.

7. Trojans or viruses.

When the computer is infected with Trojan horses or viruses, the computer will also run slowly, the network is unstable, etc., at this time, it has nothing to do with the network, routing, etc., and the anti-virus software should be used in time to disinfect the computer to avoid unnecessary losses.

8. Because there are many reasons for network instability, the phenomenon of network instability will occur from time to time when surfing the Internet. However, if you install a real-time monitoring tool for network speed testing, you can also minimize the impact.

This is very easy to understand, when your **speed is 5m per second, the maximum resource that the server gives you is 5m per second, but suddenly it is less than 2m per second, and your network speed.

It doesn't matter much.,It can only be said that the server over there is a little unstable.,There's a lack of resources****,**,To put it bluntly, it's copying.,Are you copying files from the server to your computer?,Can you understand ???

At present, the computer has become an electronic device that will be often used in both home and office, but in the process of using broadband, we will find that their Internet speed is very fast, and entering various web pages is in seconds, and ** things are very slow, often dozens of kb or hundreds of kb** speed, most people think that this is due to the problem of network operators, think that their network speed is limited, howeverWhy is the internet fast** but slowThis should be the main factor that causes the network speed to be very fast but very slow, which is also often said that the broadband network speed is not enough, if the broadband network megabyte is relatively high, the speed is naturally fast, if the broadband megabyte is relatively low, then your **speed is relatively slow, the computer's network speed is fast does not mean that the speed is fast, if you want to improve the speed, then the most direct and effective way is to improve your broadband network megabytes.

DNS is a process from domain name to IP, the speed of this travel process is to be resolved, from the work of one machine to another machine in the process, machines only rely on IP recognition between each other, so this resolution takes a certain amount of time, when the user is the first thing, you need to work with the computer and the machine at the end of the work, this conversion takes a certain amount of time, if the process of resolution is very complicated, it will take a long time, so the speed slows down.

If the user is in the first thing, the computer has a server running work, that is, the computer has other running software that needs to be networked, if there are more of these programs, then the network speed allocated to these ** will naturally become much less, and the user will install a firewall, which will make the network slower.

If you are limited by the software on the browser,It will be much slower than those professional**software,If the user uses professional **software like Thunderbolt,And with a member,Then**speed is also a qualitative leap。

The reason for the introduction, if the user finds that his ** speed is slow, do not blindly think that it is the problem of the Qingyu operator, should be analyzed from the above reasons, why their ** speed is so slow, to find out the correct solution.

Hello. In your case, please analyze and solve it from the following aspects:

1 To keep your computer normal and free of viruses and malware, it is recommended to regularly use 360 Guard, Kingsoft Guard and other tools to clean up system junk and temporary files (IE cache) generated by the Internet, and check and kill malware. Restart your computer when you're done.

2 The cat has been left open for a long time, it is very hot and hot, it is recommended to place the cat in a ventilated place as much as possible, and do not overlap with the router. So as not to be too high, otherwise there will be a fake crash, restart the cat is better, it is really not good It is recommended to change a cat with good performance (I hit ** to telecom, free to change).

3 Several computers share the network, because the router is too poor, others use P2P to watch movies, etc., it will drag the router to death, restart the router will be better, the long-term solution is to change to a better enterprise-level router.

4. Change the IP address to static settings to avoid slow computer startup, and after the IP lease expires, the sub-configuration will not be able to IP, and the network will be disconnected.

5 If someone has installed and used rate-limiting software on the network, it is recommended that you enable the ARP firewall (360 has ARP protection).

6 It is recommended to manage the boot startup items and stop the useless startup items, especially those who look at the **, ** software, run in the background at boot, and account for the network speed. Start-Run-Enter msconfig-OK-Click "Start" in the "System Configuration Utility" window-Start, except for the input method (ctfmon) and anti-virus software, the general program can be turned off. You can also use 360 and other software to intelligently optimize boot acceleration.

7 It is recommended to install only one main antivirus software, installing more than one will occupy the computer's resources, which will make the computer slower and the Internet will feel slow.

Hope it helps!!

I don't understand hi I !!

I can teach you to analyze and solve the problem step by step!!

Slow network speed is mainly caused by the above reasons, I personally recommend that you first clean up the junk process of the computer, optimize the system, and Trojan horses are also a pest.

There are a few reasons for a slow internet connection:

1. Network problems (insufficient server bandwidth or excessive load) 2. Network cable problems cause the network speed to slow down (twisted pair is not up to standard, which is manifested as: one situation is that the network speed is very slow when you first use it; The other is open.

The initial network speed is normal, but after a period of time, the network speed slows down) Third, there is a loop in the network that causes the network speed to slow down.

4. Broadcast storm caused by hardware failure of network equipment slows down network speed 5. A bottleneck is formed by a port in the network, resulting in slow network speed.

6. Worms.

The impact is causing the internet speed to slow down.

7. Excessive use of firewalls.

8. Insufficient system resources and slow network speed are mainly caused by the above reasons, I personally suggest that you first clean up the junk process of the computer, optimize the system, and the Trojan horse is also a pest! Untie.

Method: 1. Please change the time period or change the goal**. 2. Check whether the twisted pair is qualified. 3. Use the method of gradual elimination by partition and segmentation to eliminate circuit faults. Fourth, DOS is used.

The ping command tests the computers involved, with network cards, hubs, and switches being the most likely devices to malfunction and slow down the network. 5. Replace the server network card to 100m or 1000m, and install more.

NICs, dividing multiple VLANs, changing router configurations to increase bandwidth, etc. If you can solve these problems, your internet speed will be faster!

There are two reasons for this:

To improve the network speed, it depends on the access network of the ISP, which is generally divided into three types: ADSL access, FTTB-LAN access, and FTTH access.

Generally, increasing the network bandwidth without changing the network access mode will not directly increase the network speed.

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, Optimizer or 360, etc.K: The computer should have at least one valid and genuine antivirus software installed l:

NIC problem: The NIC has the appropriate bandwidth and works stably. As long as you take care of our brothers (routers, cats, hubble, network switches and their computers), our brothers promise to really do it:

You respect me, I respect you" for your faithful service. Otherwise, ride a donkey and read the record book--- let's see!

Thank you for adopting my answer!

Thank you: friend!

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