How to solve network packet loss?

Set it in the routing. The settings of each route are different. If they are similar, I will tell you mine.

To enter routing, usually enter 192.168.1.1 in the browser and press Enter. If you have a password, enter it again.

Then press pictures 1, 2, and 3, turn on 3, and change the number to a smaller value.

The principle is that the actual bandwidth is not that high, but if the setting is too large, it will cause poor quality, which is packet loss. However, if the setting is too small, the network speed will be slow. Try it slowly and it will be suitable.

How to solve the network packet loss problem?

What does the network packet loss rate here mean? When it comes to network packet loss rate, it means that during the data transmission process of our data packets, some data packets are lost due to mid-transmission. Today I searched for a keyword on the Internet which is network packet loss rate. What does the network packet loss rate here mean? Speaking of network packet loss rate, it means that during the data transmission process of our data packets, some data packets are lost due to mid-transmission. That is, network packet loss. So how to solve the network packet loss during network transmission? So let’s talk about the specific content of network packet loss. The data packets formed on our network are transmitted to another database through channels. Generally, during the network transmission process, a small part of the data packets will be lost due to some reasons, such as the distance is too large, while most of the data packets are successfully transmitted to on the terminal database. This forms a process of network packet loss. The size of the packet loss and the size of the transmitted data packet are the network packet loss rate. For example, a factory buys a truckload of goods at location A and then transports them to location B. Due to porters' handling and other reasons, the value of this batch of goods is less than that measured at location A. This process is the loss of goods. Therefore, it is the network packet loss in the network, and the ratio of the lost goods to the total amount of goods is the network packet loss rate. Usually these are just wear and tear and are normal. How to check the network packet loss rate? Click "Start-Run" on the taskbar, enter the cmd command in the run dialog box, execute the command to open the command prompt, type "ping [website address]" in the interface, the last line displayed (x loss) is the target The packet loss rate of address ping packets. How to solve the network packet loss rate? Network packet loss is a phenomenon in which data packets are lost in the channel due to various reasons when we use ping (to detect whether a system is running normally) to query the destination station. Ping uses ICMP echo request and echo reply messages. The ICMP echo request message is a query sent by a host or router to a specific destination host. The machine that receives this message must send an ICMP echo reply message to the source host. This query message is used to test whether the destination station is reachable and to understand its status. It should be noted that ping is an example of using network layer ICMP directly, it does not go through UDP or TCP at the transport layer. 1. Physical line failure If the network packet loss is caused by a physical line failure, it means that the fault is caused by the line provided by the line supplier. You need to contact the line supplier to solve the problem as soon as possible. Contact your service provider to resolve severe network packet loss. 2. Equipment failure Equipment mainly includes improper software settings, network equipment interface and fiber optic transceiver failures. This situation will cause the switch port to be in a dead state. Then you can replace your fiber optic module with a new one. 3. The network is blocked and congested. When the network is not powerful, more packets will be lost on the network when transmitting data through the network. This is usually caused by the router occupying a large amount of resources. The solution is to use show process cpu and show process mem at this time. Generally, it is found that the IP input process takes up too many resources. Next, you can check whether fast switching is disabled on the high-traffic egress port. If so, you need to use it again.

Use the show interfaces and show interfaces switching commands to identify the ports through which a large number of packets enter and exit. Once the incoming port is confirmed, open IP accounting on the outgoing interface to see its characteristics. If it is an attack, the source address will continue to change but the destination address will not change. You can use the command "access list" to temporarily solve this problem. 4. Routing error. The path error of the router in the network will also cause the data packet to not be transmitted normally to the host database. This situation is normal, and the data lost is also very small. So users can ignore these data packet losses, and this is unavoidable. The above is all about what network packet loss rate means and how to solve network packet loss. I hope it will be helpful to you.

The computer network always loses packets. Please give me 50 points for a solution.

1. From your command The window test results show that you haven’t lost any packets. If you can test, you can test again at night. Directly in the command window without any software, but do not ping Baidu, but ping the DNS address of your location, which is more accurate. To be more precise, if you are using a router, try connecting directly to the computer without connecting to the router to test. If the test still involves packet loss after directly connecting to the computer with a network cable without connecting to the router, you can call the network service provider to complain and find someone to solve the problem. By visual inspection, you should have free access to the Internet in the community. It does not freeze when there are few people, but starts to freeze when there are many people at night.

Data is transmitted on the INTERNET in units of data packets, each packet is nK, neither more nor less. This means that no matter how good the network line is or how powerful the network equipment is, your data will not be transmitted linearly (just like making a phone call), there will always be holes in the middle. The transmission of data packets cannot be completed 100%. Due to various reasons, there will always be a certain loss. In this case, INTERNET will automatically ask the computers of both parties to repair the packet and retransmit the packet according to the agreement. If the network line is good and the speed is fast, the packet loss will be very small, and the work of packet replacement and retransmission is relatively easy to complete, so the transmitted data can be approximately regarded as lossless. However, if the network line is poor, the amount of data loss will be very large, and the packet replacement work will not be completed 100%. In this case, holes will appear in data transmission, causing packet loss.

The speed of opening web pages is extremely slow, and sometimes there will be problems with part of the web page or the entire page not being displayed; instant messaging tools such as QQ frequently disconnect or It prompts that the login has timed out; it has been set to automatically obtain the IP address, but it cannot be obtained normally every time; the file download speed is slow... A large part of these failures are caused by packet loss.

Next, let’s look at how to confirm, detect and solve packet loss failures: The common method of testing packet loss is to test using the PING command, as shown in the figure. Request timed out. Indicates that a packet loss failure occurred at this moment. Reply from 220.181.6.19: bytes=32 time=10ms TTL=55 A similar display indicates that data transmission is normal. In addition, testing can also be carried out through some tool software. For specific testing methods, please refer to the instruction documents of each software, which will not be elaborated here. As mentioned before, packet loss failures are mostly caused by the following problems: worms, network cable connection distance is too long (the theoretical effective indoor transmission distance is 100 meters, but in practical applications, it is generally not more than 50 meters), network cable failure (Including oxidation of crystal head metal and other failures), operating system failure, network card failure (failure caused by the incompatibility between the working frequency of the network card and the working frequency of the network device, such as Gigabit network card with 100M network equipment, etc.; it may also be a network card Physical failures, such as natural aging of equipment or lightning strikes, etc.), network equipment failures (caused by the impact of the equipment's working environment, such as too humid, dry or severe electromagnetic interference, etc., or equipment hardware failures), network operator line problems .

5

The solutions to the above faults are: disconnect the network and check for viruses in safe mode, shorten the length of the network cable appropriately, check the network cable and re-make the crystal head, restart Install the operating system, adjust the network card or network equipment to work at the same frequency, replace the network card, change the usage environment of the network equipment or replace the network equipment, and contact the network operator to solve the problem.

What is the problem when the network packet loss rate is often 100? How to solve it

If the abnormal network delay should be below 50ms when idle, generally if it exceeds 100ms, the network speed will be slow

There is also a network delay that I don’t know how to check.

Teach you a correct way to check network delay

Click Start - Run - enter cmd to open (a DOS program will appear) and then enter: ping baidu and press Enter

Then several lines of results will appear. In the results, time=***ms is the network delay of your computer.

What is network packet loss and how to solve LAN network packet loss

When the network is congested, the switch router will discard packets outside the queue to ensure that the packets in the queue are sent normally. .

Reasons: 1. The network bandwidth is not enough; 2. The computer in the LAN is infected with a virus and sends a large number of ARP packets to block the router export; 3. The gateway in the LAN is hijacked; 4. There is no QoS or Internet access behavior in the LAN Management allows some people to use P2P downloads to seize a large amount of bandwidth, causing other users to be unable to access the Internet.

Solution: For the first point: network expansion, including hardware expansion and export expansion. For the second and third points: capture packets. Regarding the fourth point: buy software or hardware, close the P2P port or limit the speed.

How to judge network packet loss and how to solve it

Steps to check whether network packet loss is: 1. Win R to open the following interface:
