Just ordered my new V6 box along with a new hub 3 to replace a hub 2 which has been dropping SSID on WiFi..
Sadly VM will charge £99 for a second V6 even with the deal for a custom with top TV and Internet with phone, plus extras services. .... Next Wednesday 1pm to 6pm And bill is lower too as I signed up to another year with VM.
These will be required if your box is too far away from the Hub 3 to utilise a wired network connection and it is not possible to move the hub closer to the V6 box.
I do believe that an internet networked connection is required, could be wrong as new V6 box I don't believe has an inbuilt modem like the existing TiVo box, so it has to get its internet from the Hub 3.
This is why VM have stated in some instances the Hub 3 will need to be moved next to the V6 box.
