Easy to use (especially if your router has a push'n'connect button) it can almost double the reception area.
Practical, it plugs into a power outlet and can be moved without losing its settings. A red LED indicates the quality of the connection with the router (green: optimum, orange: good, and red: poor)
Even without push'n'connect, installation is not very complicated. However, it will recover the passwords for your router.
Be careful though, not to take the lead, make your first installation close enough to the router to prevent lost connections during setup.
And if you missed the Smart Wizard installation, the installation program does not appear, please feel free to do a reset (pin in the reset button) for 2 seconds.
