Test the speed and ping of your connection.

The speed test assesses the speed of your fiber, ADSL, 4G/5G or satellite internet connection from your telecom operator.
For optimal measurement, remember to cut off all downloads in progress on your computer but also on other equipment connected to your Internet box (other computers, tablets, smartphones, game consoles).
Prefer a wired connection to a WiFi or CPL connection, the latter being much less stable at high speeds.
Do not hesitate to repeat the test several times to check the stability of the results.
