Does not create a different network but actually extends the existing network (although both names are listed on the terminals). Living in a three-storey house with a modem can not be placed elsewhere than at the ground floor (except to pull the cables, what I wanted to avoid), I only had a small (and random) coverage captais first floor and nothing in the second. Nothing very serious, if not I could not therefore enjoy the music stored on my NAS other than on ... I was looking for this type of solution for some time but had never tested on (bad) advice retailers. So I found this on Amazon and was convinced by user criticism. At reception: I unpack, I read the Getting Started Guide, branch repeater in place by the manufacturer recommended, myself connects via a touch pad (thus bypassing the solution 1: Connecting WPS, but Solution 2: Connect using the installation guide via the web browser). Total Time: 5-7 minutes! I then logged in user my mobile devices (in my case, in addition to my tablet, the tablet of my wife, her phone and mine): 30 seconds per device. Finally comes the fateful test. I have not touched either my modem / router, or my NAS or any of my SONOS components (in my case, a SONOS Bridge is connected to my router) ... From the top floor, I drive without any problems a Play: 5 on the ground floor, either via streaming Qobuz or NAS; I move a Play: 3 in the room that was previously impossible to cover and the pilot of the same piece again Qobuz and NAS. This device thus perfectly fulfilled the purpose for which I bought. For 30 Euros!
