in the daily Internet, the card, slow loading and other issues often plague us. To solve these problems, we must first figure out the real state of the current network, which is inseparable from professional network speed query. Many people think that network speed query is just as simple as clicking the test button, but in fact, professional network speed query has many details to pay attention to. Choose the right tools, standardize operations, and understand the results in order to truly understand the true level of the network. This article will dismantle the whole process of professional network speed query for everyone, so that you can easily master this practical skill.
, how to choose a reliable network speed query tool?
the right tool is the first step to do a good job in network speed query, the testing principle and accuracy of different tools are different, and the wrong tool may get completely distorted results.
1, official platform class network speed query tool
such tools are launched by major operators or authoritative network agencies, such as the network speed query function in the official APP of China Telecom and China Mobile, as well as the world-renowned professional speed measurement platform such as Speedtest. Their servers are widely distributed, the test nodes are closer to the user's network line, the data is more accurate, and no unnecessary advertisements are implanted, and the test process is purer.
2, the system built-in network speed query function
BothWindows and Mac systems come with basic network status viewing functions, such as Windows can view real-time network speed in the action sheet network icon, and Mac can view network transfer rate in the activity monitor. This kind of tool does not require additional download, and is suitable for quickly understanding the general network status. However, compared with professional platforms, it lacks professional delay, jitter and other parameter tests, which can only be used as a preliminary reference.
2. What are the operating specifications for professional network speed inquiry?
after selecting the tool, the standardization of the operation process directly affects the accuracy of the network speed query results, and ignoring the details may lead to the deviation of the test data.
1, close the excess network occupancy program
before performing the network speed query, it is necessary to close the background download software, online video, cloud disk synchronization and other programs that occupy a lot of bandwidth. These programs will seize network resources, resulting in network speed query results far lower than the real internet bandwidth. For example, when downloading large games in the background, the download rate obtained by speed measurement may only be one-tenth of the actual bandwidth.
2, preferred wired connection test
if conditions permit, try to use the network cable to connect the device directly to the router or light cat when inquiring the network speed to avoid WiFi signal interference. WiFi signals are easily affected by distance, wall occlusion, and interference from surrounding wireless devices, resulting in large fluctuations in test results. Wired connections can eliminate these disturbances and obtain more stable and accurate network speed query data.
3, multiple tests take the average
the results of a single network speed query may be affected by temporary fluctuations in the network, it is recommended to conduct 3-5 tests in different time periods, and then take the average as the final reference data. For example, test once in the morning, middle and evening to avoid congestion during peak network hours, so that the results can better reflect the true level of the network.
3, how to read the results of the network speed query?
complete the network speed query, you will get a set of data including download rate, upload rate, delay, jitter, etc., read these parameters to really understand the network status.
1, download and upload rate
these are the most intuitive two parameters in the network speed query results. The download rate determines the speed at which we watch videos and download files. The upload rate affects the smoothness of sending files, live broadcasts, and video calls. Under normal circumstances, the upload rate of home broadband will be lower than the download rate. For example, the download rate of 100M broadband is about 12.5MB/s, and the upload rate may be about 1-2MB/s. The specific commitment of the operator shall prevail.
2, delay and jitter parameters
delay refers to the time when data is sent from the device to the server and then returned. The unit is milliseconds. The lower the value, the faster the network response speed. When playing games and video calls, the delay requirements are very high. Generally, the delay is less than 50 milliseconds to meet the smooth demand. Jitter is the fluctuation amplitude of the delay. If the jitter is too large, it means that the network is unstable, and it is prone to video cards and games jumping ping.
4. How to troubleshoot abnormal network speed query results?
if the network speed query results are far below the bandwidth promised by the operator, or the parameters fluctuate too much, it is necessary to troubleshoot the problem and find the root cause of the network speed.
1, check the status of hardware devices
first check the running status of the light cat and the router, such as whether the light cat's indicator light is normal, whether the red light flashes, and whether the router has not been restarted for a long time. Routers that run for a long time may cache too much data, resulting in network congestion. After restarting, the network speed query can often restore normal speed.
2, check the line and equipment connection
check whether the network cable is damaged, whether the crystal head is loose, and whether there are too many WiFi connected devices, resulting in bandwidth sharing. If the WiFi signal is weak, you can try to move the router to a more open location to reduce wall occlusion, or replace the router that supports WiFi6 to improve signal coverage and transmission stability, and then check the network speed to verify the effect.
To sum up, professional network speed query is not a simple one-click test, but a complete process from selecting tools, standardizing operations, to reading results and troubleshooting abnormalities. Choosing reliable tools is the foundation, standardizing operations to ensure accurate data, reading parameters can understand the real state of the network, and timely troubleshooting when the results are abnormal. By mastering these skills, you can easily complete professional network speed queries, so that you know your own network conditions like the back of your hand, and you can quickly locate and solve network problems when encountering them.
