The NS-01 a is perfect way to expand your home network.  It easily expands your existing WiFi network throughout your home.

If you have received a compatible CloudMesh gateway from your ISP (Aussie Broadband?), then this is the easiest way to extend your WiFi.  

You can add as many as you need to overcome poor router location, or too many WiFi unfriendly walls or ceilings.  

Use the built-in network port to connect devices such as a VOIP phone even though your modem is in another room.
