Why is my internet speed good and jet lag, and what are the problems?

Telecommunications? Move? Unicom?

Which carrier do you belong to? 2.Does "good and bad" refer to a fixed time of day when the internet is slow or irregular.

3.What do you do with your computer that you feel good and bad? 4.

Do you have a single machine or a few computers sharing a single network? 5.Are you cell broadband or regular ADSL.

Check whether your broadband account ends with LAN or ADSL. Or is it a network cable or a ** cable provided by the operator. I'm going to give you a rough idea of how you should analyze it.

First of all, the first problem is that the telecom network is relatively smooth, of course, there are sometimes good and sometimes bad, but relatively speaking, they are all relatively good. If you use Netcom and Tietong (Unicom and Mobile), there is such a problem, and the connection will be dropped frequently. Second, if it is a regular fixed daily period, then a period of time is slow, based on the operator you use (mobile telecom or Unicom) and your environment, if it is LAN that is, community broadband, because community broadband is shared, that is to say, a corridor or a building is a unit, everyone uses 10m or 20m together, in this way, it has an impact on the peak of Internet access.

If you are an ADSL user, please pay attention to the time period, if it is the peak electricity consumption, and you will have a drop in the connection, there may be high power interference near the house. If it is normal during the day and relatively slow at night, it may be caused by the aging of the line. Three.

Do you think it's slow to watch web chats QQ, or slow when you watch ** movies such as Tudou, Youku and ppstream. If it's the latter, then this one is normal, because these three are more affected by the server. The more people look at the potato, the slower your speed will be.

PPSstream means that others will see less, and you will be slower. This is because of their protocol issues, which are simply the characteristics of the software. Four.

If it is multiple computers surfing the Internet together, first see if they are watching movies in**or**, this effect is very powerful, if not, try to connect the network cable directly from the modem to your computer without connecting the router, and the other computers are not connected first. Let's see if it's still slow. Five.

I explained it a little bit in question three. Cell broadband is shared, while ADSL is exclusive, that is, similar to LAN, cell broadband is shared by several people. For example, if 10 people share 10 megabytes, then you can get the best network when everyone is useless.

And ADSL is exclusive, that is to say, you use 2 trillion or 1 trillion by yourself (this few trillion is different according to the different business you handle) Roughly like this, if there is something to add, I will analyze it with you.

Speed. The main reasons for the good and bad are the following factors.

1. Problems with the network itself (insufficient server bandwidth or excessive load) 2. Network cable problems that slow down the network speed (twisted pair.

It is not up to standard, which is manifested as: one situation is that the Internet speed is very slow when you first start using it.

The other situation is that the network speed is normal at first, but after a period of time, the network speed slows down) The network speed slows down due to the presence of loops in the network.

Fourth, the hardware failure of network equipment leads to the broadcast storm caused by fiber.

This slows down the internet speed.

5. A bottleneck is formed on a port in the network, resulting in slow network speed.

6. Worms.

The impact of the network slows down.

7. Excessive use of firewalls.

8. The system has insufficient resources.

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

In fact, there is a theory and principle of dropping data packets in the process of network transmission, so we will feel that sometimes we are fast and slow, which is normal, and on the other hand, see if the garbage in the brain has been cleaned up, because this will also affect the speed of the machine. There is also a need to see if there is a problem with the crystal head on your network cable.

There may be many reasons for this1, the internal components of the residual modem are aging, and the collapse of the base circle is replaced by one 2, the internal network card problem of the machine, which needs to be repaired by professionals3, your machine has been implanted with a Trojan horse, and someone uses your computer to ** things in the background 4, there are virus files in the machine. Affects your internet speed.

Hello Network Resource Problems It is recommended to optimize the computer.

The network is shared, and the more people there are, the more people get stuck.

This may be a problem with your internet speed.

There are many possibilities for a sudden slowdown.

2. It is also possible that there is a problem with your telecommunications (this usually does not happen).

3. It is most likely that you will be poisoned, resulting in bandwidth occupancy. You try to find out.

The optimization effect of Optimizer is not very effective for every computer.

If the landlord plays the game, the telecom broadband into the Netcom area must be stuck and famous. You can try it with Recovery Optimizer in Optimizer.

1.Your operating system is experiencing problems (including missing files, viruses, Trojans, too much disk fragmentation, etc.).

2.Problems with your browser (including missing files and being hijacked by rogue software).

3.There is a problem with your network hardware (including routers, network cards, network cables, etc., such as hardware failure, magnetic interference, etc.).

4.Problems with your network provider (including the non-telecom network you choose such as China Unicom Netcom, etc., their bandwidth is limited, generally telling you that you are 2M, but sometimes only tens of K, and the network is particularly unstable when it is busy).

5.Weather reasons, including thunder and lightning, etc.

6.Some operating systems have a limit on the number of network connections (for example, the default number of connections for XP is 10) and hardware drivers are not equal.

Copyright application, this answer is that petty bourgeois men exclusively own the copyright, and other plagiarists are too shameful to be stupid

3.The amount of servers you want to access or the game servers you want to log in to is too large, resulting in overwhelmed servers, reduced efficiency, etc.

4.There is a problem with the ** program design you want to access, and there is a problem with the program design of the game server, resulting in too many bugs, which affects your normal browsing or playing games, making you feel that the network speed is slow.

5.The server you log in to is Netcom, and you are a telecom network, there is a difference in speed when accessing each other, this is quite obvious when playing games, when you access the Netcom server in the telecom network, it is painful and very slow.

And so on, that's pretty much it.

If you have a problem with the Internet equipment, it will affect the network speed if you use it for too long, or go to the Netcom company for repair!

Call 10000 customer service to ask telecom maintenance personnel to come to check the line.

My internet speed is also running like this.

What do you use to access the Internet.

It's a lot better to change the Internet device.

If you use the wide shout and belt directly, which may be the connector problem of the line, find the hidden noise of Netcom to check.

There is a way to increase bandwidth: start running --- --- Group Policer program (. In Local Computer Policy, step through the Computer Configuration Administrative Templates Network QoS Packet Scheduler branch.

On the right side of the screen will appear the QoS Packet Scheduler policy. Then click Limit Reservable Bandwidth for the subproject on the right. In this case, a detailed description of "Limit Reservable Bandwidth" will appear on the left.

Here we can learn some basic scenarios for "limiting reservable bandwidth".

Once we understand this, we can set the "Limit Reservable Bandwidth". Click "Properties" next to "Display" under "Limit Reservable Bandwidth" (or select the sub-item "Limit Reservable Bandwidth", and then right-click "Properties"), the "Limit Reservable Bandwidth" dialog box appears, click "Description" first, and then learn more about "Limit Reservable Bandwidth" to determine the percentage of connection bandwidth that can be retained by the system.

After that, we can go into the settings for the other 20% of the bandwidth. Click on "Settings". "Settings" gives us three options (not configured, enabled, disabled), select "Enabled", then set the % next to the bandwidth limit to 0%, and press OK to exit.

In fact, there are many reasons for slow internet speeds.

First, the network itself is a problem.

The server you want to connect to is on a server that is running low on bandwidth or is overloaded. The solution is very simple, please change the time period and then go up or change the goal**.

Second, the effects of worms cause the internet speed to slow down.

Third, the network speed is slowed down due to network cable problems.

Fourth, there are loops in the network, which causes the network speed to slow down.

5. Broadcast storm caused by hardware failure of network equipment causes network speed to slow down.

Sixth, the excessive use of firewalls.

There are many reasons for slowness, such as 1

A ** web page cannot be opened for a long time.

The reason is that during the peak period of Internet access, many users access the same hotspot**, because the **server can not handle it, or the bandwidth is narrow, there will be a slow network speed, and the web page cannot be opened for a long time, please avoid the peak hours of Internet access or visit other sites instead.

2. Due to the failure of Internet nodes, the network system automatically routes in a roundabout, resulting in slow network speed. Please be patient and wait for the system to recover.

3. Due to"Cats"The quality of the problem is slow, and the Internet speed is slow. Please replace it with a good quality"Cats"。

4. The electrical index of the line is too low and mountain-resistant, which causes the slow Internet speed, please replace the high-quality line.

5. Outside"Cats"If the connection rate with the host host is low and the Internet speed is slow, please reset the interface parameters.

6. If you run an advanced operating system on a low-end machine, and the Internet speed is slow, please choose the operating system and browser that are suitable for your computer.

7. Due to the improper setting of the browser, the Internet speed is slow, please set the number of days of retention of the web page in Chongtong Muhuai, set the cache directory of the browser on the hard disk with the highest transmission rate, and increase the capacity appropriately.

There are many reasons for determining the speed of the Internet, and with my work experience in Netcom for so many years, there are the following points:

First: **The line is too long, the network cable is too long, and the network speed must be slow!

Second: The network speed of the application is small, and the network speed will be slow!

Third: the computer operating system has no intention of maliciously**, affecting the computer boot speed, running slowly, and the network speed will also be slow!

Fourth: That is, what the friend above introduced: when the computer is fast, the network speed is fast; When the computer is slow, the network speed is slow; I feel that there should be malicious programs in the computer**, it is recommended to use a security guard to clean it up, and at the same time use antivirus software to try it if it is allowed.

As a reminder, if your computer is infected with a more serious malware** (Trojan), you may need to reinstall the system!
