The Wi-fi works great relay, except 1) that comes with RJ45 network cable was not working in my case, 2) to be re-set the relay after each power failure of the Livebox, and finally, 3 ) when using a PC with Windows XP for the setting, you should not have to apply the Windows updates from say a year for the setup software does not crash! Fortunately I had an older PC XP still in working condition .... Besides all that, the relay works perfectly.
