in the process of daily use of the network, many people will encounter problems such as video cards, soaring game delays, and interrupted file transfers. These abnormal performances are often closely related to the high packet loss rate. Packet loss rate refers to the proportion of the number of lost data packets in the network to the total number of sent data packets. It is one of the core indicators to measure network stability. This article will comprehensively sort out the common causes of abnormal packet loss rate, and provide a system of troubleshooting and processing solutions to help you accurately locate the problem and quickly restore a smooth network experience.
want to solve the problem of excessive packet loss rate, we must first clarify the root cause of the abnormality, and there are obvious differences in the processing methods corresponding to different incentives.
1, hardware equipment failure
routers, switches, network cables and other hardware devices are the basic carriers of network transmission. Once a failure occurs, it will directly lead to an increase in the packet loss rate. For example, the router overheats and dies during long-term high-load operation, the cable connector is oxidized and loose, and the network interface card driver is old and incompatible.
2, internet bandwidth congestion
when a large number of devices in the same network environment perform high-bandwidth operations at the same time, such as multiple devices simultaneously downloading large files, live streaming or watching 4K videos online, internet bandwidth will be quickly filled up, and data packets exceeding the bearer limit will be discarded, eventually resulting in increased packet loss rate. This situation is particularly common in home networks and small office networks.
3, external environmental interference
wireless device's signal is vulnerable to external interference, such as microwave ovens, Bluetooth speakers, adjacent WiFi networks, etc., will interfere with the WiFi signal in the 2.4GHz band, resulting in loss of data packets during transmission, which in turn pushes up the packet loss rate. In addition, extreme natural environments such as thunderstorms may also affect the stable transmission of fiber optic signals.
before starting to solve the problem, it is necessary to confirm the current packet loss rate level through professional testing to provide data support for subsequent investigation.
1, use the system's own command detection
Windows and Mac systems have their own network detection command, Windows users can press the Win + R key to open the running window, enter cmd to open the command prompt, and then enter "ping gateway address -t" or "ping public DNS address -n 100", wait for the detection to complete You can see the specific value of the packet loss rate; Mac users can execute a similar ping command through the end point to get the packet loss rate data.
2, with the help of professional tools to detect
if you need more accurate and comprehensive detection results, you can use professional network detection tools, such as Speedtest, PingPlotter, etc. These tools can not only detect the packet loss rate, but also synchronously test the network delay, jitter and other indicators to help users understand the network status more comprehensively and provide richer reference data for troubleshooting abnormal packet loss rates.
clear the root cause of the increase in packet loss rate, we can take corresponding measures for specific problems, effectively reduce the packet loss rate and restore network stability.
1, troubleshoot and repair hardware failures
first check the network hardware devices one by one, power off and restart the router, and observe whether it can return to normal; check whether the network cable connector is firm, and replace the new network cable if oxidation occurs; update the network interface card driver at the same time to ensure the compatibility of the device and the system. If the router has been in use for more than 3 years and the packet loss rate is abnormal frequently, it is recommended to replace the new device with more stable performance.
2, optimize internet bandwidth allocation
log in to the background management page of the router, open the bandwidth speed limit function, allocate reasonable bandwidth resources for different devices or applications, and avoid a single device occupying too much bandwidth; at the same time, close the network connection of idle devices to reduce unnecessary bandwidth consumption, and relieve network congestion from the root cause.
3, avoid external signal interference
If you use a wireless WiFi network, the 5GHz frequency band is preferred, which is less subject to external interference and has stronger transmission stability; place the router away from the microwave oven and Bluetooth device, while avoiding being blocked by walls and metal furniture; In addition, you can modify the WiFi channel in the background of the router to avoid channel overlap of adjacent networks, further improve the signal stability and reduce the packet loss rate.
solve the current problem of abnormal packet loss rate, it is necessary to do daily maintenance to prevent the packet loss rate from rising again and maintain the stable operation of the network for a long time.
1, regular maintenance of network equipment
develop the habit of restarting the router regularly, it is recommended to restart once a week to help the device release the cache and avoid long-term high-load operation; at the same time, clean the dust on the surface of the router, keep the device well ventilated, and prevent the packet loss rate from increasing due to overheating; in addition, regularly check the router firmware version, timely update the official upgrade package pushed, and repair known network vulnerabilities.
2, rational planning of network use
try to avoid a large number of high-bandwidth operations at the same time, such as downloading large files at night or during the trough of network use; for home networks, you can guide your family to stagger the time of using high-bandwidth applications, reduce the probability of network congestion, and maintain a stable packet loss rate.
To sum up, the packet loss rate is a key indicator affecting the stability of the network, and its abnormal increase is often caused by hardware failure, network congestion, external interference and other factors. To solve the problem of packet loss rate, it is necessary to identify the root cause through professional detection, then take targeted treatment measures, and do a good job in daily maintenance. As long as you follow the method of this system, you can effectively reduce the packet loss rate and maintain a smooth and stable network environment for a long time.
