When setting up access points with the RFX9600 you need to :
1.Give your Pronto a fixed IP
2.Use the same SSID and passphrase
3.Allocate different channels for the routers, however in the rooms closest
to the main router other keep the channels further apart.
4.In the Pronto channel setting(advanced wifi), it's best to tick all of the channels used,(multiple access points)
This helps when passing between routers.
5. Make sure you give the RFX a fixed IP
6 in the access points disable DHCP
