The signal output from WiFi equipment – including the router which we supply – is restricted by regulations.
The signal may not cover all of properties with thick stone or masonry walls. In such cases, the first step is to locate the router as close to the centre of the area you want to cover as possible.
A second measure is to install a WiFi range extender or bridge such as the Apple Airport Express.
A third option is to use Homeplug or Powerline adapters to transmit Ethernet signals over your electrical wiring system. We use Devolo and TP-Link powerline adapters which offer nominal speeds of 500 or 600 Mbps and seem to work well. The real performance of such adapters is rarely more than a quarter of the nominal speed but this is adequate in most circumstances.
