Works perfectly after I confess myself to be taken 2 times the installation. The quick installation guide recommends to install a computer software (Windows only) to install the device. I started doing that, but it worked strangely. Then I downloaded the complete manual on the manufacturer's site PT Link (is very easily), and I then found another procedure easier, via the web interface of the device, with nothing to install on the computer. Some tips that will save you time: - Check that the unit is in "extender" mode (it can also serve as an access point "AP"). - Check that the DHCP server of the device is disabled. - Change the IP of the device and the gateway (eg Freebox is your IP with 255 at the end).
In short, I had to spend 20 minutes in total setup, and now it works like a charm. Very very happy with my purchase, and I'm not sure the other devices that are 2 or 3 times more expensive are easier to install.
