Re: Superhub on Virgin??
The SH is rubbish on wireless and more than likely the house itself isn't helping. I've got a top class router in one part of my house but in my office, wireless is poor.
So I use a Powerline adaptor to punt ethernet over the mains from my router to the office Powerline. I connected the Powerline to a hub/switch and connected a port on the hub to a wireless extender in my office. This extender uses the same SSID as my router so I can move around the house wirelessly.
This solution is ideal in the type of house described - but involves laying out dosh.
Don't even think in terms of the wretched SH wireless decently reaching any part of the house where difficulty is currently experienced.
My advice is at your risk.
