Re: What do I need to connect a second V6 box upstairs?
V6 boxes require separate connection to the broadband, there's three options for that
* Use power-line adapters (they need to be on the same electrical circuit)
* Install an Ethernet cable from your Super Hub to the location upstairs
* Use WiFi
What about trying the box on the upstairs cable, using the WiFi for the broadband connection. It would give an idea as to if the cable upstairs is usable or whether you'd need to book en engineer to replace the cable down to the splitter.
