in daily office, online entertainment or remote collaboration, many people have encountered problems such as network cards, frequent video buffering, and interrupted file transfer, and most of these conditions are closely related to the abnormal packet loss rate. Packet loss rate refers to the proportion of lost data packets in the network to the total sent data packets. Once it exceeds a reasonable range, it will directly affect the network experience. This article will explain in detail the detection method of abnormal packet loss rate, the idea of incentive investigation, and the corresponding solutions to help users quickly retrieve a stable network state.
to solve the problem of excessive packet loss rate, it is first necessary to accurately detect the current packet loss rate value, confirm the severity of the abnormality, and provide a basis for subsequent investigation.
1, use the system's own tools to detect
Windows system users can execute "ping gateway address -t" or "ping public DNS address -t" through the CMD command line to continuously send data packets and view the return results. The proportion of the number of "request timed out" to the total number of requests is the real-time packet loss rate; Mac and Linux users can execute "ping -t destination address" at the end point to get the relevant data of the packet loss rate.
2, with the help of professional network tools to detect
if you need more accurate multi-dimensional data, you can use professional tools such as Speedtest and PingPlotter. Such tools can not only detect the packet loss rate, but also display parameters such as network delay and jitter. Some tools can also track the transmission path of data packets to help quickly locate the location of nodes with abnormal packet loss rates.
finding the root cause of high packet loss rate is the key to solve the problem. Hardware, line, signal interference and other factors in the network environment may cause abnormal packet loss rate.
1, hardware equipment aging or failure
routers, switches, network interface cards and other network hardware used for too long, there may be problems such as component aging and poor heat dissipation, resulting in a decrease in data packet processing capacity, which in turn leads to an increase in packet loss rate. For example, if the router antenna is damaged and the network interface card driver is not timely updated, it will affect the normal receipt and transmission of data packets.
2, network signal interference or insufficient coverage
wireless environment, Bluetooth devices, microwave ovens, and adjacent WiFi signals may interfere with WiFi signals in the 2.4GHz band, causing data packet loss and pushing up the packet loss rate; if the router is placed in a remote location, or there are thick walls blocking, WiFi signal coverage is insufficient, and the packet loss rate of end point devices will also increase significantly.
Aiming at the problem of high packet loss rate caused by hardware factors, through reasonable hardware adjustment and upgrade, it can effectively improve the network condition and reduce the packet loss rate.
1, troubleshoot and replace faulty hardware
first check the appearance and connection status of the router, network cable, network interface card and other hardware, if the network cable is found to be damaged, the router indicator light is abnormal, you can try to replace the network cable or restart the router; if the packet loss rate after restart is still not improved, you can replace the standby router or network interface card for testing to confirm whether the packet loss rate is abnormal due to hardware failure.
2, optimize router placement and signal
place the router in the center of the room, away from the source of electrical interference, and adjust the antenna angle to enhance WiFi signal coverage; the router that supports dual-band can guide the end point device to connect to the 5GHz band first, which has less signal interference and can effectively reduce the packet loss rate.
In addition to hardware optimization, by adjusting network-related settings, data packet loss can also be reduced, and the packet loss rate can be effectively controlled within a reasonable range.
1, update device driver and firmware
timely update network interface card drivers and router firmware, vendors will update and fix known network compatibility issues and data packet processing vulnerabilities to improve device network performance and reduce packet loss rates. Update drivers can be done through Facility Management or the brand's official website, and router firmware can be upgraded online on the background management page.
2, adjust internet bandwidth and connection number
If multiple devices occupy a lot of bandwidth at the same time, it will lead to network congestion and increase the packet loss rate. Bandwidth limit can be set in the background of the router to allocate priority bandwidth for key devices or applications; at the same time, unnecessary background network connections can be closed to reduce data packet transmission pressure and avoid abnormal packet loss rate caused by congestion.
In summary, to solve the problem of excessive packet loss rate, it is necessary to follow the process of "detection-investigation-optimization". First, the packet loss rate is accurately detected through system tools or professional software, and then the incentives are investigated from hardware failures, signal interference, network settings, etc., and finally the hardware is optimized or adjusted. As long as the above methods are operated one by one, the packet loss rate can be effectively reduced, the stable and smooth network environment can be restored, and the network needs of daily office and entertainment can be met.
