In our 3-storey residential house there was always in the basement and attic problems with the wifi reception.
As already hung a Devolo adapters on the router, everything happened very simply:
Simply plug it in and configure the software on the PC.
I have the same password and the same SSID on both devolo and the router set.
Now when I run with the tablet / laptop / mobile phone through the house searches, this automatically the strongest stations from the three, without anything I set müsste.Daher 5 stars because I wanted just that.
