I'm getting a garden office put in. A sparky will run a 13a power supply from the house mains. My question is, to provide a network, will I be able to use a powerline adapter and if so, can these things double up as we already have one pair serving the TV? It will probably be easier to run LAN to the TV than out to the garden so if the answer is no I can do some planning. Of course, the best answer is 'wait and see', which I shall do for the femtocell O2 boost box that runs the phone. But the family will be outraged if they lose TV even for half an afternoon so I need to do some thinking now... Thanks!
