Why would you want to? The Billion will do the job on its own without the Hub One.

Having said that it is both possible and easy. You need to set the Billion up as an Access Point.

Assuming that there's no setting options in the menu to do this all that you need to do is switch off DHCP then set the Billion up with a ununused fixed IP adress in the range 192.168.1.2-63, for example 192.168.1.50. Connect it with an Ethernet cable between LAN sockets at each device.

I'm looking to improve my Wifi speed/connection upstairs (main router situated downstairs)
