Power adpators for wifi some questions?

[clipperjay]

I wanted to buy some power adapters, but the issue is upstairs is on a separate ring from down stairs?
will this be a problem or will it flow through the neutral wires?
Router is upstairs
Downstairs another PC?

I have the home plugs upstairs and downstairs and they work perfectly 

My router is downstairs and I have a blu-ray player upstairs connected to the network via a homeplug

What make is yours?
I was looking at these for about £30.00
The kids wanted me to buy a network adapter for the Xbox 360 @ £45 so was thinking this must be better and just hard wire the Ethernet cable direct from the plug?

I have the TP Link ones 

Bought them from Amazon

Behind my TV i even have a 5 way box so my Xbox, TV, Blu-ray, Sky box etc are all connected to the internet via a home plug
