Sometimes it can be useful to run an internet speed test to find out how good your connection is at home or at work. An internet speed test tool (or speedtest) is a service you can use to find out if your ISP is delivering on its speed promises.
With the arrival of fiber and the improvement of network technologies, Internet subscriptions now offer connection speeds that can reach very impressive figures. But the quality of your provider (good or bad) does not explain everything. It is also worth noting that your speed Internet may vary depending on the device you are connecting from; for example, sometimes the phone's browsing performance is better than that of the PC, or vice versa. This can depend on many things, such as the type of connection (ethernet or wifi), your internet setup or simply the quality of your wifi chip.
What is an Internet speed test and why is it important?
An Internet speed test is a test that will measure the quality and speed of your connection. It generally performs two measurements: a measurement of the download speed and a measurement of the data sending speed (upload).
For the most accurate test possible, it is recommended to disconnect all devices that could have access to the Internet and interfere with the results. So check that no other device is consuming bandwidth and close all browser tabs, keeping only the one that will perform the measurement.
Moreover, do not hesitate to carry out the test several times in a row to check the stability of the results.
It is advisable to do this when you notice that your internet speed is slower than usual. You can also do it when you change your internet service provider (ISP) and want to check that the speed you see is close to the speed you promised.
If not, this is a good tool to start investigating the weak link in your connection: your computer, your Internet box (or its positioning), your ISP?
