How to do broadband testing? Detailed steps and precautions to share

daily Internet access, many people will encounter problems such as video cards, slow downloads, and high game latency, but they are not sure whether it is a problem with the broadband itself or a device failure. At this time, professional broadband testing has become a key step in troubleshooting problems. This article will share the practical skills of broadband testing in an all-round way from the operation process, tool selection, precautions to result interpretation, and help you accurately grasp the true state of your own network and quickly locate the root cause of network anomalies.

How to conduct basic broadband testing?

basic broadband test is the first step to detect the network rate, the operating threshold is low, suitable for ordinary users to quickly understand the network status, without complex equipment.

1, prepare the testing environment

Before

test, close all programs that occupy the network, such as background downloaded files, online videos being played, cloud synchronization software, etc., to avoid these programs consuming bandwidth and leading to low broadband test results. If conditions permit, try to use the network cable to connect the computer directly to the LAN port of the light cat or router to eliminate errors caused by WiFi signal interference.

2, choose the test tool

ordinary users can choose mainstream online broadband test platforms, such as Speedtest, speed measurement network, etc. These platforms are easy to operate. After opening the webpage, click "Start Test", and the system will automatically match the nearest server to test the current download rate, upload rate and network delay. Some broadband operators also provide official broadband test tools, which can be accessed through the operator's APP or official website entrance. The test results are more referential.

What details should be paid attention to before broadband testing?

many users' broadband test results are inaccurate, often because they ignore the details of the preparation before the test, which directly affect the authenticity of the test data.

1, avoid network peak hours

broadband test results will be affected by the time period, 7:00 pm to 10:00 pm is the peak time for home Internet access, at this time the overall bandwidth occupancy rate of the cell is high, even if your broadband package rate is up to standard, the tested rate may be lower than the nominal value. It is recommended to choose non-peak hours such as before 8:00 am and 2:00 pm to 4:00 pm for testing, so that the results obtained are closer to the true speed of broadband.

2, troubleshoot hardware connection problems

Before

test, check whether the network cable is plugged in tightly, whether the indicator light of the light cat and the router is normal, if the red light flashes of the light cat, it may be a failure of the optical fiber line, and need to contact the operator for maintenance. If using WiFi test, make sure that the device is in the core area covered by the router signal, away from microwave ovens, Bluetooth speakers and other interference sources to avoid signal attenuation and distortion of broadband test results.

How to deeply interpret the broadband test results?

the completion of the broadband test, not only look at the download rate of the number, but also combined with the comprehensive interpretation of the indicators, in order to accurately determine whether the network is normal.

1, pay attention to the rate of compliance

The download rate of the

broadband test should reach more than 90% of the nominal rate of the package. For example, if 100M broadband is handled, the test download rate should be above 90Mbps. If the results of multiple tests are far below the nominal value, it may be that the bandwidth is limited, the line is aging or the operator's port problem. You can contact customer service for investigation. Upload rate is also an important indicator. Generally, the upload rate of home broadband is 10% to 20% of the download rate. If the upload rate is abnormally low, it will affect video conferencing, file uploading and other operations.

2, analyzing latency and jitter data

Delay refers to the time it takes for data to be sent from the device to the server and then returned. The unit is milliseconds. The lower the delay, the faster the network response speed. Games and video calls have higher latency requirements. Generally, latency below 50 milliseconds is a good state. Jitter refers to the fluctuation range of the delay. Jitter is too large to indicate that the network is unstable. It is prone to video cards and games jumping ping. At this time, the jitter data of the broadband test can help you locate the network stability problem.

How to troubleshoot broadband test abnormalities?

if the broadband test results are abnormal, such as the rate is not up to standard and the delay is too high, it is necessary to gradually investigate the problem and find the root cause to solve it.

1, troubleshooting equipment failure

replace the test equipment first, such as using another computer or mobile phone for broadband testing, if the results are normal, indicating that there may be a problem with the network interface card driver of the original device, or the device itself is faulty, you can try to update the network interface card driver and restart the device. If the test results after replacing the device are still abnormal, check the router, restore the router to factory settings and reconfigure it to rule out the problem of aging or setting errors in the router firmware.

2, contact the operator to detect the line

if the broadband test results are still not up to standard after troubleshooting equipment problems, it may be an external line failure, such as fiber bending, loose joints or operator port failure. At this time, you can call the operator's customer service phone to provide screenshots of the broadband test results, and apply for staff to come to the door to detect the line and port. The operator will test the line attenuation, signal strength and other indicators through professional equipment to find the fault point and repair it.

To sum up, broadband testing is an important means to understand the status of the network and troubleshoot network problems. From the basic operation process to the preparation of details, to the interpretation of results and abnormal investigation, each link affects the accuracy of the test. Mastering scientific broadband testing methods can not only help you confirm whether the broadband is up to standard, but also quickly locate network faults and provide a basis for optimizing the Internet experience. Regular broadband testing can also detect network hidden dangers in time and make the Internet smoother.
