The local connection sends more and receives a lot of error packets, and the network speed is super

Let me tell you, someone attacked your computer to send you spam packets, if you don't bother to redo the system, and then install 360 security guard first, the second step is to install Kingsoft net dart, adjust the mode to an untrustworthy state, and then the next better antivirus software! 360 doesn't work, (one of the best shackles on the market: it's better to buy a Kaspersky), and Norton does.

If you are troublesome, you can go directly to the next Jinshan net dart, but it is difficult to say whether your network speed will recover.

You have an unstable network, there are several possibilities:1It's a small chance that you're having a problem with your physical connection.

2.Insufficient bandwidth for your current web application and need to increase the bandwidth.

3.Someone uses BT software to maliciously grab bandwidth, causing you to be unable to use the network normally. Or someone uses some network management speed limiting software to restrict the following machines.

4.Viruses in the LAN computer keep sending junk data to the network, blocking your normal data passage.

I have not summarized the above points completely, but it is difficult to really check them. There is currently a router on the market called Immunity Wall, which seems to solve several of the problems I listed.

I've encountered this problem, the problem is in the computer room of your network service provider, you call the customer service, and ask it to change the port for you, and it's OK.

It feels like you're a lot like Tietong... Call the service provider.

Whether it is on the Internet or a LAN, we need to start from the "local connection" and configure the network parameters appropriately. However, in the process of actual networking, we sometimes find that the "local connection" may have a variety of inexplicable faults, which often lead to our inability to set the network parameters in a targeted manner, whether it is on the Internet or the local area network, we need to start from the "local connection" and make appropriate configurations for the network parameters. However, in the process of actually surfing the Internet, we sometimes find that the "local connection" may have various inexplicable faults, which often lead to our inability to set the network parameters in a targeted manner, thus affecting our Internet efficiency.

In order to effectively improve the efficiency of Internet access, we must master some troubleshooting methods related to "local connection"; No, this article lists several fault phenomena that are more likely to occur in "local connection", and puts forward different countermeasures for each fault phenomenon, which I believe can bring you gains! Solve the "Local Connection" Restricted Fault Some ADSL users often use the built-in PPPoE dial-up mode of Windows system when using broadband dial-up Internet access under the Windows XP SP2 operating system. However, when using this method to surf the Internet, these users may find that the display status of the "Local Connection" icon in the network connection list window is often inexplicably adjusted to "Restricted or No Connection", but the Internet operation can be carried out normally in this state. So how did this strange state display glitch occur, and how do we eliminate it?

If the "Local Connection" display status changes to "Restricted or No Connection" for no reason, this is usually due to the fact that the NIC is not assigned a fixed IP address. Under normal circumstances, when we find that the display status of "Local Connection" is abnormal, we can often try to set a static IP address for the network connection first, which can often solve many inexplicable network failures for us. Once we find that the local network connection does not use a fixed IP address, we can click the "Start" "Settings" and "Network Connection" commands in turn, and then in the network connection list interface, right-click the "Local Connection" icon with the mouse, and execute the "Properties" command from the right-click menu to open the property setting window of the local connection; In the "General" tab page of the window, check the "Internet Protocol" item, and click the "Properties" button, check the "Use the IP address below" option, and try to set the IP address of the local computer to "and then set the IP address of the local gateway to "By default, the factory IP address of most ADSL devices is, finally click the "OK" button, and restart the computer system, believing "Local Connection" Most of the state-limited faults can be resolved.

First of all, it feels like you are sharing the Internet in a local area network, and we will analyze it with the elimination method. First of all, you said that the network cable can be plugged into other computers to access the Internet, indicating that the end of the network cable interface is normal, and the conclusion is that 1. Your computer may have software and hardware problems that cause you to not be able to access the Internet. 2. Your computer is restricted by the server or router.

Then you can access the Internet by plugging in other network cables, and finally come to the conclusion that the above problems do not exist, and the conclusion is self-contradictory.

1. It has nothing to do with IP address allocation, because other network cables are also available after connection.

2. Since the computer connection network cable can access the Internet, why bother repairing the network connection.

3. The NIC address should not be affected.

From your current statement, your question, I can't explain. It could be some detail that went wrong.

It may be that your router has turned off the automatic assignment of IP addresses, of course it is easy to use if someone else's is not turned off, you plug in the network cable to see what your default gateway is, what is the difference with someone else's, and you can configure it manually.

First check whether the light of your network card is on, it is on when you plug in the network cable, and when you unplug it, it is off, and then check whether your DNS is the same as that of the router, or use the router's disk to assign a new IP

Your next software, change the value of your computer's network card.

The data itself is sent more than it is received, normal!

If the internet connection is slow, you can consult your network operator!
