with our Ookla speedtest

To have a reliable result:

  • Run the test when no other user is surfing.
  • Don't download during the test.
  • Close the other applications, windows and tabs of your navigator.
  • Check, using your anti-virus, that your computer is not the target of a virus or malware.
Test on wired?

Your computer must be connected to the modem via a network cable, and Wi-Fi must be disabled during the test.

Wi-Fi test?
  • Make sure you're connected to the right Wi-Fi network. You should connect to your own network.
  • Test your Wi-Fi in several places: start by testing the connection next to your modem to have a reference point.

How to optimize your internet speed?

Fiber to the home

Optical fiber makes it in some regions possible to enjoy an ultra large bandwidth: downloads at up to 220 Mbps and uploads at up to 25 Mbps. The whole family online at the same time, without delay or interruption, it’s not a dream! Discover optical fiber.

Your modem

  • Restart your b-box modem to update its software. Pressing the power button on your b-box is sufficient to turn it off, next press the button again to turn on the modem. Then wait for the lights to burn continuously.
  • Do a line test to make sure your phone line is working properly.

Wi-Fi, cable or PLC?

Your browser

  • Do not forget to regularly update your browser and to clear your cache.
  • Open as few windows and tabs as possible.

Your device: PC, mobile, tablet…

  • Downloading slows down your connection. The same applies to peer-to-peer programs.
  • Close unused applications. These slow down your computer and connection.
  • Enable the energy-saving options of your computer.
  • Make sure your computer is free from viruses, spyware or adware. We recommend Norton to protect your computer.
  • Make sure to have at least 10% available space on your hard drive.
  • Do not forget to regularly restart your computer.

Connected devices

The more people at home are surfing, gaming or watching TV at the same time, the less fast the connection will be.
