Cheers taf, I have had a look into things a little more, I only have one power socket upstairs where my 3.0 Hub is so I will need a through adapter as VM say connection is not very good through an extension lead.
Also VM Dianne has a youtube clip which will help.
TIA

Update
I just noticed that my promotional rate finishes this month so I rang retentions who were somewhere warm.
The CSA was unusually good and told me to ring again after the 21st March when my current promotion finishes.
Getting onto the V6, she said I can have an engineer out and the powerline adapters FOC, so the engineer will come on the 7th. What did surprise me was that the 15th was the earliest for delivery at home of the V6 through the VM online method.
