What should I do if the network packet loss rate is too high? Common causes and effective solutions

in the process of daily Internet access, office or gaming, many people have encountered web loading cards, frequent video buffering, and disconnection of online conferences. These problems are often related to the high rate of network packet loss. Network packet loss rate refers to the proportion of data packets lost during data transmission to the total sent data packets, which directly affects the stability and fluency of the network. This article will analyze the common causes of network packet loss rate in detail, and provide actionable solutions to help you quickly troubleshoot and solve network problems, and restore a smooth network experience.

, how to judge whether the network packet loss rate is too high?

want to solve the problem of network packet loss rate is too high, we must first accurately determine whether the current network packet loss rate is in the abnormal range, to avoid misjudgment lead to useless work.

1, through the system command detection network packet loss rate

Windows system users can press the Win + R key to open the run window, enter cmd to enter the command prompt, and then enter the "ping 8.8.8.8 -t" command to continuously test the connection with the public DNS server. After pressing Ctrl + C to stop, the interface will display the number of data packets sent, received and lost. Calculate the proportion of the number of lost to the number of sent is the current network packet loss rate. Mac or Linux systems can enter "ping 8.8.8.8" for testing, and can also get network packet loss rate data.

2, with the help of professional tools to detect network packet loss rate

In addition to the system comes with commands, you can also use Speedtest, 360 speed measurement and other professional network tools, these tools can not only test the network speed, some will also come with the network packet loss rate detection function, the operation is more intuitive, suitable for users who are not familiar with computer operation. Generally speaking, the normal network packet loss rate should be less than 1%, if more than 5% will obviously affect the network experience, which is an abnormal situation that needs to be solved.

2. Common reasons for high network packet loss rate?

finding the root cause of network packet loss rate is the key to solve the problem, there are differences in incentives in different scenarios, we can investigate from three dimensions: hardware, environment and network services.

1, hardware failure caused network packet loss rate increased

routers, light cats and other network core equipment run for a long time, there may be overheating, firmware aging and other problems, resulting in a decline in data packet forwarding ability, thereby increasing the network packet loss rate. In addition, network cable damage, loose crystal head will also cause data transmission interruption, especially in the old community or wiring non-standard environment, the network cable is squeezed, the probability of oxidation is higher, easy to cause abnormal network packet loss rate.

2, network environment interference leads to an increase in network packet loss rate

wireless WiFi environment, if there are multiple WiFi signals in the same frequency band around, or there are interference sources such as microwave ovens and Bluetooth devices, electromagnetic interference will be generated on the WiFi signal, resulting in data packet loss during transmission, pushing up the network packet loss rate. In addition, insufficient internet bandwidth can also cause problems. For example, when multiple devices perform large file downloads, 4K video playback and other large traffic operations at the same time, network congestion will cause data packet queuing timeout loss, thereby increasing the network packet loss rate.

3. An effective solution to reduce the network packet loss rate?

for the problem of high network packet loss rate caused by different reasons, we can take corresponding solutions to accurately reduce the network packet loss rate and restore network stability.

1, troubleshoot and repair hardware failures to reduce network packet loss

first restart the light cat and router, turn off the power and wait for 30 seconds before re-connecting, most of the temporary faults can be solved by restarting. If the network packet loss rate has not decreased after restarting, you can check whether the network cable crystal head is loose, try to replace the network cable or re-press the crystal head. If the device is used for more than 3 years, it is recommended to replace the new device with stronger performance to solve the problem of high network packet loss rate caused by hardware aging from the root cause.

2, optimize the network environment to reduce network packet loss rate

wireless WiFi users can log in to the router management background, switch to the 5GHz frequency band in the wireless settings, which has fewer interference sources and stronger signal stability, which can effectively reduce the network packet loss rate. At the same time, place the router in the center of the room, away from microwave ovens, refrigerators and other electromagnetic interference equipment to reduce signal occlusion. If the network packet loss rate is too high due to insufficient bandwidth, you can contact the operator to upgrade the bandwidth, or limit the use priority of high-traffic devices to avoid network congestion.

To sum up, the network packet loss rate is too high is a common problem affecting the network experience, from judging whether the network packet loss rate is abnormal, to troubleshooting hardware, environment and other incentives, and then to take targeted solutions, as long as the steps can effectively reduce the network packet loss rate. Daily use should also regularly check the status of network equipment, optimize the network environment, reduce the probability of network packet loss rate from the source, and ensure that the network is always in a stable and smooth state.
